For safe, non-toxic carpet, both natural and synthetic fiber options can be a healthy choice.
The post outlines my top picks in the zero and low-VOC (volatile organic compounds) categories for residential and commercial use.
This includes a look at the carpet fiber, backing, products used during installation, and padding (underlay).
Even folks who are chemically sensitive can do well with carpet in the home.

The Ideal Carpet Does not Contain:
- Flame retardants – the most harmful types are usually found in polyurethane padding or felt backing, but aluminum hydroxide can be added to the fibers. Antimony is found in some flame retardants used in carpet. (A small amount of Antimony can also be found as part of some polyester fabric fabrication methods). Bromine has also been found in carpets.
- Permethrin pesticide mothproofing which is added to many wool carpets.
- Antimicrobials which can be added to the backing, the glues, and the face fiber. Pyrithione zinc and/or potassium oleate are often used in the fiber.
- Stain repellents like PFAS-based treatment which are often added to the textile top layer. PFAS (Per- and polyfluoroalkyl substances) aka “forever chemicals” are a priority to avoid in my opinion. Note that Scotchgard is no longer a PFAS-based treatment and PFAS are being phased out in general.
- Anti-static treatment like quaternary ammonia which can be added to the fibers.
- SBR (Styrene-Butadiene Rubber) is at the base of the fibers in conventional carpet.
- Padding off-gassing – rebounded polyurethane, memory foam, and rubber, all off-gas.
- Phthalates – usually found in vinyl/PVC backings as well as EVA and TPE foam
- Fly ash – which can be added to backings, and can contain mercury, lead, and arsenic.
- Toxic metal stabilizers like lead and cadmium.
- Toxic adhesives which can be required for glue-down installation or at the seams.
- VOCs – a number of chemical additives are a part of conventional carpet – from the dyes and processing of the fibers to the topical fiber treatments, backing glues, backing materials, carpet padding, and installation tapes and glues.
What to Look for in a Carpet:
- A fiber that is not treated with toxic chemical treatments – wool and other organic fibers like sisal and jute are the best options.
- Undyed wool without pesticides is in theory the purest option, but it does have a strong natural odor from the natural wool oils.
- Natural latex is usually touted as the safe adhesive between the fibers and the backing. I have reservations about natural latex which are outlined in this post on mattresses, and I’m not sure if the same precautions need to be taken with carpet.
- PET and PTT two types of polyester are also safer fibers (in terms of off-gassing)
- Solution-Dyed Polyester means spills are not able to be absorbed by the fibers. It’s as close to stain-proof as is possible reducing the need for stain guard treatments.
- PFAS-free -in the last few years this has become obtainable.
- Zero-VOC is ideal!
- Certifications? … are not useful in this situation. Green Lable Plus, a certification created by the carpet industry, has an upper limit of off-gassing that it appears that all carpet in North America can meet. Greenguard is very rarely used to certify carpets.
Wool Carpet Brands
Wool carpet is a natural choice that can be untreated and undyed.
It does not contain flame retardants and the best brands would not use topical treatments.
The backing will be a natural latex in most cases.
1. Earth Weave
Earthweave makes a wool carpet, with no mothproofing and no other treatments.
It does contain latex.
I always prefer the undyed wool option for the extremely sensitive. This is one of the top brands.
2. Nature’s Carpet
Another great brand, Nature’s carpet is also made of wool.
The Dark Green line does not have mothproofing and uses undyed wool. The backing contains natural latex and jute.
The Medium Green line and Light Green line contain permethrin mothproofing. The Medium Green has jute and synthetic backing adhesive.
The Light Green has synthetic backing adhesive and synthetic backing (not jute).
3. Whitfield Natural Textiles
They have two lines: Pure Nature and Nature Friendly.
Pure Nature line is made using an untreated wool yarn for the face, an untreated cotton and jute primary backing, and an untreated jute secondary backing. This is all held together with a 100% natural rubber adhesive.
All of the products are made with undyed, untreated British wool tarn. That means no mothproofing and no antimicrobials – no topical treatments whatsoever.
Their entry level product is the Nature Friendly line, that is the same wool face with a more traditional backing system.
This product will me more comparable to some of the Natures carpet medium and light green lines.
They manufacture a 100% recycled wool underlayment, which is available in 3 different thicknesses.
4. Kaleen PureLife
100% all-natural wool that has been hand-loomed in India and colored using GOTS-certified organic dyes.
The PureLife line contains no permethrin (or other insecticides), no stain guard treatments (like PFAS), no synthetic latex, no polyester backings, no antimicrobials, and no flame retardants.
Made with 100% wool, natural rubber latex, with a cotton and jute backing.
Home Depot wool carpet – I tried the Natural Harmony brand Glacial wool/polyester blend and it did have a slight classic carpet chemical odor. It’s not what I would use myself. Hibernia – I sniffed Hibernia pre-2018 and it does have a wooly smell (as you would expect), but not a chemical smell. The company changed ownership in 2018. They do use mothproofing (typically permethrin is used on wool carpets).
Seagrass & Jute Carpet Brands
1. Seagrass
I really like seagrass carpet because of how it feels underfoot.
The DMI brand makes one I like that is not dyed or treated with insecticides or other chemicals. It contains natural latex.
2. Sisal
EarthSisal from Sisalcarpet.com: makes EarthSISAL, which is marketed as “the first completely natural, biodegradable sisal carpet”.
No latex, no VOCs and a natural felt backing.
Synthetic Carpet Brands
Most of the no or extremely low-VOC carpets are made from polyester (PET or PTT).
There are a few polyester carpets that are too high in off-gassing for me.
I list out the ones I have found are the best.
In general, your typical nylon carpet (which is the most common carpet textile) is higher in odors and off-gassing compared to polyester, though generally lasts longer.
1. Fresh Haven by Empire Today
Empire Today eliminated their 0-VOC HomeFresh, but replaced it with a very similar Fresh Haven line.
Both are a solution dyed PET polyester.
HomeFresh carpet contained charcoal, the new Fresh Haven sounds like it either contains charcoal or zeolite, which both absorbs some VOCs.
HomeFresh claimed to be 0-VOC, Fresh Haven has not made that claim but claims to have no odor.
It has a built-in felt backing, which seemed benign to me. The felt is synthetic (polyester).
The HomeFresh carpet was free of PFAS.
I got a sample of HomeFresh that was a few months old, but it has stayed bagged up, and I did not pick up classic carpet off-gassing at all. Though it is not 100% odorless to the most extremely sensitive, it is very close. If you don’t have an extreme sense of smell you may very well find this odorless.
It’s available in the US (not Canada). For $350 off try this discount link.
It is installed by tack-down or glue-down methods, the company says in an email. Be sure to test all components if you are chemically sensitive.
2. FLOR
FLOR makes carpet tiles that can be arranged as rugs or as wall-to-wall carpet.
Their carpet lines are made from nylon (polyamide).
FLOR has a different type of off-gassing chemical odor than typical carpet, but it’s very low in off-gassing and I definitely find it off-gasses faster than typical nylon carpet.
I like that you can air out the carpet tiles before installation as well.
All of their carpets are free of PFAS (aka “forever chemicals”) or any topical stain guard treatment.
For flame resistance, they use mineral fillers like unrefined aluminum ore (bauxite) and calcium carbonate (limestone) in the layer below the yarn.
The backings have improved over the last few years. They used to only have vinyl or bitumen. Now they have either a PVC-free bio-based plastic made with bio-based and recycled fillers or recycled PVC.
I would look for the CQuest™Bio or CQuest™BioX which are the PVC-free lines.
There is an antibacterial treatment called Intercept but they don’t say what it’s made of.
Installation
You will need to test their sticky tape “dots” that attach these tiles to each other. Most sensitive people will be fine with them.
3. Mohawk SmartStrand
Another type of polyester carpet, SmartStrand is PTT (Triexta) instead of PET.
Polyester carpets are consistently lower in off-gassing since they are treated with fewer chemicals. I would say this one is extremely low VOC.
HomeFresh seemed better to me than SmartStrand or FLOR, though the difference is slight. Between SmartStand and FLOR, the level of off-gassing is likely very similar though the odors are different.
Since polyester is inherently more stain-resistant, there also seem to be fewer (or less harmful) stain-resistant coatings used on it.
Their stain-resistant Nanoloc is described as a “spill-resistant shield made from nanoparticles”. It’s not clear what that actually is.
It does not have Scotchgard and they are claiming no topical stain guard treatments which can wash out (and they have said no PFAS are used, in an email).
It is OEKO-TEX 100 (and as of Jan 2024, that means it’s free of PFAS).
Other Mohawk Carpet Lines
Mohawk EverStrand is also made of polyester (PET) recycled water bottles, it was extremely similar to SmartStrand to me.
Recycled polyester (PET) which can contain phthalates and more metals.
On the other hand, Mohawk EnviroStrand was not as good in terms of off-gassing to my nose, it was more like a conventional carpet odor in my experience, despite also being solution-dyed PET.
However, it did test free of metals like lead and antimony. (Though positive for PFAS in 2018. Should be free of PFAS since 2019).
Mohawk Street Thread is a more conventional nylon carpet (with the usual off-gassing), but their Duracolor stain-resistant technology did test free of PFAS in a 2018 test by the Ecology Center (which is no longer available online).
Shaw Brand 100% High-Performance PET. Shaw is a competitor to Mohawk. They also have PET carpets. I got samples of their Bellera PET line. Based on the samples I got of both brands I would say that I picked up a more noticeable new carpet odor off of the Shaw PET. I personally wouldn’t use this one myself. (I am not affiliated with either brand and there is one big factor that I can’t hold steady and that is the age of the samples). Shaw is free of PFAS.
4. Engineered Floors DreamWeaver PureColor
The company Engineered Floors makes a solution-dyed polyester carpet that is free of PFAS.
This was higher in odor than I expected.
Though, of course, that’s absolutely my subjective experience.
And I did not have this sample at the same time as I had other carpet samples.
It also is very much based on the age of the sample wise, which is why you need to get multiple samples from a brand you’re considering.
Other Carpet Brands Free of PFAS:
All of Home Depot and Lowes carpets and rugs are free of PFAS/PFCs.
Home Depot
I would suggest getting samples of Home Depot’s polyester options by Home Decorators Collection, Lifeproof (polyester/Triexta blend or 100% Tiexta), Traffic Master (olefin fiber and polyester), and Mohawk.
I tested all the polyesters/Triexta carpets from Home Depot. In my estimation, the Lifeproof lines including Petproof were lower in perceptible VOCs than Traffic Master brand, but not as good as Mohawk SmartStrand, Envirostrand, and Air.o or HomeFresh.
My top choice from Home Depot is the Lifeproof Triexta with the Lifeproof polyethylene cushion underlayment.
I have an in-depth review and comparison of all the Home Depot polyester/Triexta lines in this article (as well as their best carpet padding).
Lowes
All indoor wall-to-wall carpet is free of triclosan, organotins, ortho-phthalates, vinyl chloride, nonylphenol ethoxylates, coal fly ash, formaldehyde, added heavy metals.
All their indoor residential carpet and rugs are free of PFAS chemicals.
Other Lines
Some Lines by Shaw, Tarkett, and Bentley as outlined here are free of antimicrobials, flame retardant chemicals, fly ash, polyvinyl chloride (PVC), polyurethane, synthetic styrene-butadiene latex as well as PFCs.
Interface Carpet and Tarkett are free of PFAS/PFCs.
Staton Carpet LION indoor/outdoor nylon was low in odor & off-gassing – definitely quite good for a nylon carpet. The company said in an email they are free of PFAS/PFCs.
6. Inexpensive Polyester Carpet
The Ribbed Carpet Tile from Flooringinc, also was odorless to me, based on the sample I received.
It’s very thin with almost no backing and might not be the most durable of options but it is simple and cheap.
It’s a peel and stick and the adhesive part of the sticker was shockingly low in odor.
I also got samples of their Impressions Carpet Tiles, and the Ribbed Smoke Grey Indoor/Outdoor Area Rug, but is was more difficult to judge those as they arrived smelling like rubber from their nearby rubber stock.
If you have carpet in your house that is still off-gassing VOCs, use the strategies outlined in the article on how to off-gas new carpet.
Commercial Grade Carpets
It is a lot harder to find low-VOC commercial carpet.
I have reviewed and sniffed a few of the ones that claim the lowest VOC levels.
Synthetic Carpet
FLOR: Most of their carpets are commercial grade.
They claimed they had the lowest VOC levels in the industry in 2017, though in my comparison with the other types above, I did not experience that as true based on smell.
However, in the conventional nylon carpet category, this very well might be the case.
They have Green Label Plus which every carpet can probably attain now and is not a low level of VOC in my opinion. It doesn’t help to distinguish between brands if all of them can reach this certification. This certification was made by the carpet industry.
However, when testing their carpet it did not have that tell-tale new carpet smell.
The initial off-gassing was as strong as other regular brands in 2017 but in recent years I’ve gotten more samples and the odor is very very low. And it seemed less offensive (I know everyone is different here).
But, what did impress me was that the sample off-gassed way faster than other brands that have the tell-tale new carpet smell.
Flocked Flooring
Forbo makes this interesting product called Flotex. It’s a mix between a carpet and a vinyl sheet flooring.
From a distance, it looks like carpet, but up close it seems like a slightly hairy floor.
The ease of cleaning would be a huge upside with this flooring. For those with allergies who don’t feel they can get regular carpet clean enough, this would be a better choice.
It’s also a good flooring for home gyms.
There is some off-gassing in this flooring, but it’s minor compared to many carpets, mostly it seems from the backing (which is phthalate-free).
You can buy Flotex at Green Design Center.
Wool
Wool can also be a good option for commercial spaces. However commercial companies are more reluctant to use wool because of the price.
Godfrey Hirst wool commercial carpets showed test results with very low VOC levels. Though they did have that classic carpet smell, and they do contain mothproofing (permethrin). They have a full Declare Lable here.
J Mish formally Woolshire wool is also rated for commercial use, I found it lower odor than Godfrey when I tested it – it smells wooly but not like chemicals. It does have moth-proofing in it. It smelled similar to Hibernia brand.
Some of Earth Weave’s lines can be used in light commercial applications, and those do not contain mothproofing or other chemical treatments. In a light commercial setting, this is the “greenest” way to go.
If I was choosing carpet for a commercial space I would consider Earth Weave first, then Woolshire, and then FLOR.
Can Carpet Ever Be a Healthy Flooring?
Because carpet does collect dust, mold spores, pesticides, flame retardants, and all types of contaminants and allergens that ride on dust, a HEPA vacuum like the Nilfisk is a good idea for cleaning.
The FLOR tiles can be taken apart and even washed in the bathtub or outside.
While Forbo’s Flotex can be scrubbed and washed like a resilient (sheet) flooring since the fibers are extremely short.
Chemicals Used in the Installation of Carpet
Conventional carpet is either glued down or tacked down. The seams are melted together.
Wool Carpet Installation
Nature’s wool carpet is installed very similarly to a conventional carpet. It is stretched onto a tack strip. Seaming tape (standard latex) is used on the back and melted together.
The wool felt padding can be either glued or stapled down to the floor first.
On a concrete floor (basement, slab, or upper-level concrete) the company suggests attaching it as usual. They don’t recommend a plastic vapor barrier underneath.
I would not put wool carpet on a slab or basement floor. But I would put this on an upper-level concrete floor that has completely dried and does not have moisture coming up from a lower level.
They have the same installation instructions for their jute and plastic-backed versions.
Some brands of wool carpet can also be glued down.
Homefresh installation
HomeFresh was installed with double-sided tape, you’d have to ask about Fresh Haven.
Carpet Tile Installation
FLOR tiles are installed with tape onto the backing – they are taped to each other. It is not also taped down to the floor underneath/subfloor. It stays in place with traction.
The tape has the same odor as clear packing tape but is well-blocked by the plastic backing.
Flocked Flooring Installation
Flotex is installed only with a glue-down system. See Forbo’s branded glues and recommendations.
Carpets with a conventional synthetic backing can be glued down with AFM 3 in 1, a non-toxic carpet glue.
Non-Toxic Carpet Pad/Underlay
Padding (Underlay) for Wool Carpet
Nature’s Carpet sells a (wool) felt padding. No chemical treatments.
Do not use rebond pad (bonded urethane) with jute-backed carpet, as it’s incompatible.
Two other options apart from wool felt are a synthetic felt pad or a rubber pad.
For any Carpet type that requires padding
Synthetic rubber is recommended by Green Building Supply. This virgin rubber does have a slight odor. How long this takes to dissipate depends on the product and how sensitive the person is.
I would test a new sample of this. The antimicrobial here is quaternary silsesquioxane.
Homefresh has built-in felt padding. No additional padding is needed/recommended.
Some FLOR tiles have a PVC-free backing. This new vinyl-free plastic is likely to be 0-VOC. No additional padding is required or recommended.
Polyethylene carpet pad is almost zero-VOC, it’s far preferable to the usual polyurethane carpet padding. Lifeproof from Home Depot also has a polyethylene option, this is a foam and it can go under most carpets. It does have an added antimicrobial but it is still a better option than most other options in terms of VOCs.
EVA foam carpet pad – is not 100% odorless but is a low odor, low VOC foam that is preferable to polyurethane in terms of off-gassing but it does often have phthalates. This one is breathable.
Felt padding can be purchased through some big companies and can be used under many synthetic carpets. This is often a mixed plastic that is recycled content. The one I linked to does not have an added antimicrobial. Mohawk also has a felt padding that can go with other carpet types. It’s likely to be 0-VOC.
I avoid memory foam carpet pad, rebonded polyurethane, and most SBR rubber (especially the very dense kind or recycled tires). I would also avoid regular (solid, not rebonded) polyurethane if possible or if you are highly sensitive. It could be just fine for some people.
Under rugs, you can use a natural latex rug gripper
Where can you Install Carpet?
Rugs on the floor and carpet only on stairs are a better idea.
Over a Concrete Slab
Nature’s carpet, made of wool, also claims that it can be installed over concrete without a vapor barrier because it’s breathable. I would not install this over concrete, certainly not the ones with jute and or natural latex backing. A wool carpet with a synthetic backing will fare far better over concrete, in my experience.
FLOR carpet tiles have a vinyl backing or PVC-free plastic backing. Both plastics are a vapor barrier. If you are OK with installing a vapor barrier over your concrete slab or basement then this is an acceptable installation. I prefer not to block moisture in a slab/basement since it’s always trying to dry to the inside. I have seen a vapor barrier over a concrete slab become a mold risk in many homes.
On An Upper-Level Wood Subfloor
Carpet of any kind installed over a wood subfloor is much easier and is much less of a concern.
If you are installing carpet on a first floor with a humid unconditioned basement below, then you should be careful because moisture is making its way up.
Non-Toxic Rugs
FLOR, sisal, and wool carpets can be installed as rugs instead of wall-to-wall carpet.
See my post on non-toxic area rugs for the full list of options for area rugs.

If you had to pick a carpet for a home you own that you are currently living in with young children, but will likely rent out after you move again, which would you choose? I want to go with a wool one but I worry about longevity and how it will hold up to renters. It’s specifically for a stairwell – no where else in the house has carpet. Do any of these brands make good stair runners if we were to continue our hard flooring on the stairs? Thanks for your insight!!
Corinne Segura, Building Biologist
Yes, certain styles of wool can be used on the stairs. That would be my preference, but that’s really just because I don’t the feel of walking on plastic carpet. I also wouldn’t go with polyester if you want it to last a long time, so your other option is the typical nylon fibers.
Karen Wilson
Thanks for all of your great info. I found some Karastan Smartstrand carpet that I like but they only offer memory foam pad. Not sure what to do.
Corinne Segura, Building Biologist
it just depends on if you have chemical sensitivities and how sensitive you are to that off-gassing. if you don’t have chemical sensitivities it’s not too bad really but it will take a few weeks perhaps to air out.
anoop
It looks like Mohawk stopped making Air.o.

Conventional carpet pad adhesives can be avoided altogether by using a hot melt glue gun instead to tack down the carpet pad. The glue gun needs to be a high power (~300W) model and the glue stick should have extended working time to avoid hard lumps. Look for the Arrow “3-minute” glue sticks. This worked perfectly when I had felt carpet padding installed on a concrete slab. The hot glue bond to the concrete was stronger than the felt pad, meaning that if one pulled hard there would be chunks of padding left on the concrete. Thus the hot melt glue was every bit as good as a chemical adhesive.
I also had the installer use the Kool Glide carpet seamer to reduce the smoke as compared to conventional heat seamers, and I just said “no” to any additional chemical adhesive carpet seam sealers.
The carpet pad was the very clean “QuietWalk” 7/16″ 8lb felt pad for carpets. Not to be confused with the similar thin product for laminate flooring. The QuietWalk carpet pad is made with heaty bonded recycle fibers and is sold by Lowes. This pad is firm and supportive, has no smell or outgassing, and will most likely last much longer than foam. I believe that this is the best carpet pad on the market.
Our carpet was a relatively clean nylon carpet from Shaw with a conventional backing. Some of the more modern carpets with newer soft backings had a disagreeable chemical presence.
I was very pleased with our carpet installation. There was a bit of new carpet smell for a week or two, and now there is no smell or any other chemical effect on me at all. I accomplished this off by hiring a carpet installer directly. I interviewed four installers and selected the one that was willing to address my health concerns. I was happy to pay them a bit more for a healthier outcome.
Josh
Hello Corrine, My Name is Josh I am from Sydney Australia. About 6 months ago we installed some new carpet throughout our house. The carpet we installed was this: Redbook ‘Kashmir’ col/Linen 100% solution dyed nylon textured loop
pile on 10mm DUNLOP foam underlay. https://www.redbookcarpets.com/products/kashmir?gad_source=1&gad_campaignid=19755478546&gbraid=0AAAAApXw3bo0-sDOpmx_lEni4qdWucLiA&gclid=Cj0KCQjwwZDFBhCpARIsAB95qO2bSTXFbH9lWh6OhkIAOd4JtjFAVE6NFVZGTYL7KkXOcaU5RnLKXxwaAunREALw_wcB
We have had continual problems with offgassing ever since. I was wondering if you might be able to help me with some potential solutions that may help us rather than removing all of the capret and starting again with a low-voc carpet. Do you have any suggestions?
Corinne Segura, Building Biologist

Kim
Hi Corrine,
What would you recommend pad and carpet-wise for high traffic stairs in a wet Seattle house with wet kids and wet dogs in a home that we we’ll only live in for a few years and then keep it as a rental property? I have a good dehumidifier, but still wary of wool. Do wool carpets smell like wet sheep?
I want to get rid of the carpet all together but the rest of the family just wants to replace it. I have MCS and need the best compromise! Thanks for your advice.
Corinne Segura, Building Biologist
wool smells wooly yeah you will have to get samples to see what you do well with
Lacie
Would the lifeproof polyethylene pad from Home Depot be a problem on concrete slab as far as creating mold in the same way the underlayment of lvp would? We have performed a calcium chloride test and it was good. I think it’s bc of the slab being painted in the room in question when it was built 18 years ago (not by us). We previously had carpeting (PU padding) and it seemed ok after we ripped it up as far as mold. Is there a breathable PE padding out there or is there a more non toxic PU (or other padding) that would be better suited for a slab home (not a basement)?
Corinne Segura, Building Biologist
I don’t think that one is vapor open. I cover the topic of flooring on a slab as fully possible here https://corinnesegura.substack.com/p/mold-preventative-flooring

Hi Corinne, curious your thoughts on this— We just had mohawk smartstrand installed yesterday in living room and on stairs with Mohawk’s felt underlay. They tacked down, except for a seam across our living room, where they had to do the glue strip. Today our 1-year-old has been struggling with widespread ***** for the first time ever. We have vacuumed like crazy, cleaned everything even before we brought him home after the installation. Do you think he’s reacting to remnants of dust from the installation or possibly the glue? I guess he could still be reacting to the carpet even though it’s hypoallergenic. In the short term, we are in touch with his doctor of course and he has been given ****** but in the long term I don’t even know what to do now.
Amanda Aszman
That’s strange it changed hives to asterisks. Putting it here with spaces so you have the correct info! H i v e s
Corinne Segura, Building Biologist
yes it’s part of the google approved comment filter for med-cal words. I can’t really speak on that topic directly. But I don’t believe Mohawk claims that carpet is hypoallergenic themselves, unless that is hidden somewhere. Also that claim on carpet can just mean that it is easy to fully vacuum it clean than other brands not that people don’t have reactions to it. I would also look at if you removed a moldy carpet before this one as that is a more common cause.
Amanda Aszman
Thank you so much and thank you in general— I have referenced this blog post probably 1000 times!

Hello! What are your thoughts on this carpet pad? It will be in our playroom so I want something healthy for the kids. I see it’s memory foam but is Greenguard Gold. I want what’s best for the kids! 🙂 Thanks!
Corinne Segura, Building Biologist
I mention memory foam in the post. GGG isn’t relevant for me.
J Green
What is your opinion on Healthier Choice, 100% HIGH-DENSITY MEMORY FOAM CARPET CUSHION? It is Greenguard Gold certified.
I see you answered this previously. Can you please elaborate on why GGG is not relevant? I just bought a GGG couch with memory foam!?
Thank you!

Hi Corinne, thanks so much for all your rigorous work! I live in Australia and have purchased a nylon carpet through a boutique carpet supplier because I was given to believe that the carpet was the best in terms of chemical free/low VOCs etc. It is manufactured by a company in the Netherlands and has a number of ratings for the carpet. I know you don’t hold ratings up as saying much, but I wondered if you have an opinion about the following and if the ratings are strict enough for all the criteria you’ve listed?
Emissions Dans L’air Interieur (this carpet has an A+ rating)
Eurofins GOLD
Blauer Engel
I’ll be interested to hear your thoughts?
Corinne Segura, Building Biologist
I’m don’t know european certifications in great detail

Hi Corrine,
Thanks for all the helpful info. I hope you are still doing well with brain rewiring! I’m starting that very soon.
I have an opportunity to buy an affordable home which is pretty good for MCS in many ways but it has a lot of 6 year old carpet of unknown origin.(synthetic – but can’t tell if nylon or poly) (Could be from Home Depot as that’s a popular place in so many places ,including here on Vancouver Island) Haven’t been able to find other flooring samples that I don’t react too to install instead, and even hardwood would need to be oiled – but I react to most oils etc.,even the nice,lovely organic kinds.
So,wondering if putting rugs – or something else – on top of the carpet would actually make it safe for me,my daughter and our cat.
I don’t tend to react to older carpets and didn’t to the carpet at this potential home, but with very compromised health with autoimmune,ME etc and problems with halides (thyroid), and little ones, I want to find the safest solution.
Would you mind sharing any solution-ideas if you have any? Thanks in advance.
LeAnna D
Thank you for your extensive work. You mentioned on a photo above that you would not use carpet in a basement. Is this due to moisture buildup and mold concerns? Do you have an article about possible alternatives? Thank you, again.

Tamra R.
Can you link to the felt padding that you recommend? You state above that the one you linked to does not have the antimicrobial, but I don’t see the link. We have decided on a Polyester carpet by Tarkett that did not have an odor (on the sample), but we’ve had a harder time finding a nontoxic pad. We have narrowed it down to the Lifeproof pad from HomeDepot or a felt pad from RugPad USA. They have an option that can be used with wall-to-wall carpeting. Besides the felt pad link, I would love to know you thoughts on Tarkett and/or RudPad USA products. Thanks!

“the one i link to” – at the beginning of that paragraph
Tamra R.
Okay, I got it now. I didn’t realize the bold lettering was a link. Have you heard of Tarkett carpet or the RudPad USA products as far as nontoxic options? Thanks so much!

Hello there- I am a mother of two young children and we are going through a re carpeting process. Carpet is not my first choice at all for a healthy home, but it’s a long story not worth the detail here…..
We have been offered quite a large amount of mohawk silk strand silk natural artistry series carpeting. Based on your blog here– it seems that this is an “okay” brand. Can you tell me in more detail if this is product contains chemical flame retardants or fermaldehyde. or (with a good pad and installations) it is relatively clean.
I appreciate this article so much as well as your expertise.

Hi Corrine,
Thank you for your site and the wealth of information you share on here. My family suffers from severe multiple chemical sensitivity from mold exposure in our home. We were told by our physician that all the old carpet had to go as it cannot be decontaminated. We recently installed Smartstrand carpet 50% triexta/50% PET polyester with the mohawk Smart All Pet Cushion. A week after installation in 2 rooms only, we are still unable to live in our home.
During installation I checked in once the padding was down and didn’t sense any chemical smell but once the carpet was in the smell was horrendous, causing nausea and headaches. We didn’t go with Air O because according to our local reps it is being discontinued so we couldn’t get samples and hardwood was not in our budget. Do you have an article specific to remediating new carpet offgassing? I read a few of your offgassing remediation articles but didn’t see anything specific to new carpet but I could have overlooked it. Would a carbon sheet/blanket be effective in removing offgassing smells if layed over the carpet?
Right now we are ventilating with open windows, using an industrial air scrubber with carbon filter in one room, using fans to push the smelly air out, and using baking soda pans all over the rooms but after a week it is still so bad. Our VOC monitors measured an average of 25 the first day it was installed, and after a week the average is about 12. Usually our home is a 1 or 2. Any advice you have for me would be so appreciated!!
Corinne Segura, Building Biologist
yes there is an article called how to get rid of new carpet smell
Corinne Segura, Building Biologist
did they glue the carpet to the undelayment?
Lisa
Ok, thanks. I checked with them beforehand to make sure they wouldn’t be using glue and they said they would use tack method but I wonder if they glued the seams or something as the smell is really intense. I will check on that because we’re supposed to do the 2nd half of our upstairs in 2 weeks and we may just need to find somewhere to pre air the carpet longer before we do that.
For the zeolite pellets, is it safe to put those directly on new carpet?
Irene Sherman
Thank you so much for your much needed and invaluable information.
I had to vacate my house after I brought in a new mattress set. Formaldehyde took over my house, engulfing the entire inside and garage. It was only there for 3 days, covered over with old heavy plastic, with fans and windows open. It was insidious, causing me to get rid of ALL the carpet, upholstered furniture, linens, and my clothes. Yes, ALL.
As that was happening, my health was stripped too. Where could I stay to get better became a frightening quest. Two hotels that advertise a Free and Clear environment were a devastating experience as I pulled up the covers to be engulfed with synthetic perfume. Another claimed no perfumed air fresher was used and the employees could not have perfume on while at work. As I entered the building I was blasted with synthetic perfume. The agent said that is not perfume,that was an odorizer!
Thank you so very much from one with extreme MCS,
Irene Sherman

Thank you for the valuable information. Do you have any suggestion of how to rank these choices: Shawnee: Wool/Polysilk; Mowhawk -Global Perspective Smart Strand; and Mowhawk – Merino Wool
Jaclynn
Hi there, looking for a new carpet for my kid’s bedroom. I see you had a number one choice from Home Depot but for Lowes you only listed that all of their carpets are free from several chemicals. Does this mean I should be ok if I pick a carpet from Lowes, or do you really just not recommend them at all?
Corinne Segura, Building Biologist
i have not reviewed the lowes carpets in detail, i do not know the VOC levels
Abi Harter
Hello, I am looking at 100% wool carpeting advertised as undyed and untreated, but is has recycled pp backing. Would you consider that a good choice for people with sensitivities to VOCs? Should I be asking what adhesives would have been used to fix the backing to the carpet?
Corinne Segura, Building Biologist
yes that will work for most people, yes ask about adhesive and get a sample
Tina
Hello, again! Thank you for answering my questions about carpet padding. I believe we will go with the LifeProof polyethylene pad from Home Depot that you recommended. My only other question is regarding synthetic fiber carpet padding. I’m guessing if it’s made with recycled synthetic fibers, it’s not good.
Corinne Segura, Building Biologist
felt padding doesnt really have any offgassing but is usually treated with antimicrobials and possible more
Tina
Got it. So, in your opinion, the polyethylene pad is the best option?
Tamara
Thanks for all the valuable information. I’m looking to install the Mohawk Smartstrand carpet in our bedrooms. The carpet company we are using sells a Condensed, pure urethane foam pad from Leggett & Platt, called Napa. There site does mention it contains an antimicrobial, Fresh Dimension. I reached out to them to see if it contains the following: BHT, SBR (Styrene Butadene Rubber), or Flame Retardants. They claimed it doesn’t contain any of those items. Does this sound like a decent option or iss there anything else I could ask about?
Thanks!
Corinne Segura, Building Biologist
We don’t know what a lot of the antimicrobials are but when they are used under another flooring it’s not likely to be a very worrisome part. there is some offgasssing to polyurethane foam, though not too much if it’s regular not rebonded, no memory foam. and dont glue down
Jamie
What are the theoretical risks of antimocrobials in padding?
Do you worry about mold growth with a pure wool padding?
Corinne Segura, Building Biologist
offgassing from some
wool padding fine on wood subfloor
robf
wow amazing and dare i say life saving content here.
safe to say in your opinion that Forbo has real separation in non toxic quality over Flor in terms of safety? Plus using for workouts so moisture wicking prob better in Forbot.
Corinne Segura, Building Biologist
Flotex is probably objectively better for gyms and is easy to clean, it doesnt really look like a carpet once you get close up. in terms of which one is less toxic it’s hard to say, might be FLOR because they have non-PVC options. close call though, can’t say objectively which is safer without having the full details of ingredients and VOCs from both which we dont have.
Deanna
Hello Corinne!
I want to start by thanking you for your research on safe flooring. I wanted your help on finding a high quality carpet that will not show wear especially on stairs from Lowe’s. I am sensitive to chemicals and chemical smells. With that being said I replaced the carpet in my home 9 years ago and went with Shaw and it looks worn. I want to invest in fixing this issue in a safe and smart way. Thank you for your help and wisdom in this matter. I am grateful for your help!
DeAnna
Corinne Segura, Building Biologist
wool is the most durable, followed by nylon (which is the highest offgassing) followed by polyester (which has some very to no offgassing options)
Bindhu
Hey Corinne!
I found your post when I was looking for kids safe carpets and paints, thanks for everything!
I have a few questions about carpet cushion/padding:
I was looking at Healthier Choice 100% high density memory foam carpet cushion, it is Green Gold plus certified, does it mean it does not have of the nasty Fire retardants, PFAs etc.?
Appreciate your help.
Bindhu
Corinne Segura, Building Biologist
it’s one of the hightest offgassing carpet pads, it could also still have flame retardants and antimicrobials. GreenGuard Gold only tests for VOCs (though it seems like every product can meet this certification now), not semi-VOCs like flame retardants and antimicrobials. I don’t think there are PFAS in carpet pad. If you are OK with the VOC level then ask about flame retardants for sure.
Bindhu
Thank you for your quick response Corinne.
I contacted Healthier Choice tech support and asked if the following are present in the product mentioned above:
Flame retardants
Permethrin pesticide mothproofing
Antimicrobials
Stain repellents
Per- and Polyfluoroalkyl Substances (PFAS) Based treatment
Phthalates
Fly ash
Toxic metal stabilizers like lead and cadmium.
Toxic adhesives
And the response was : ‘The only item mentioned on your list that we have in our Cushion is an antimicrobial. The name of the antimicrobial is UltraFresh by Microban. We have used the product in our cushion for over 20 years with no health related issues.’
Should I be concerned about the UltraFresh Antimicrobial. I checked your previous posts about this Antimicrobial and there was not much info.
Or would you suggest that I choose the Home Depot’s Lifeproof Thick Waterproof Premium Plus Carpet Cushion with Air Channels, which is mentioned in your post above. I have no idea if this Homedepot product has any added chemicals.
Could you please guide me in the right direction, I am in a confused state and in a hurry.
Thank you in advance.
Corinne Segura, Building Biologist
We dont know what UltraFresh is at all. I would not concentrate on the antimicrobial, I would go for a lower offgassing material like the polyethylene.
Bindhu
Thank you Corinne, appreciate your help.
Bindhu
Hi Corinne,
Just wanted to update you and get your inputs.
I contacted Home Depot’s Lifeproof about their carpet padding and they told me 1) it has No Prop 65 chemicals
2) it meets California’s 1350 indoor air quality testing
3) and uses UltraFresh antimicrobial.
Is ‘No Prop 65 chemicals’ a good thing? Please advise.
Corinne Segura, Building Biologist
no prop 65 means no chemicals known to cause cancer or reproductive harm.everything meets californias indoor air quality levels
Tina
Hello, thank you for providing all of this information. It’s so helpful! I have a quick question about Healthier Choice Carpet padding. I’ve been looking at the Healthier Choice memory foam carpet padding to go under our wool carpet. I’m confused about your comment above that “it’s one of the highest off-gassing carpet pads.” What makes it so high in off-gassing compared to other pads? It’s made of 100% virgin frothed polyurethane foam and is UL GREENGUARD Gold & CRI Green Label Plus Certified. The rep I spoke to claims that they don’t use any flame retardants or PFAS chemicals. I’m just trying to figure out what I’m missing here. I don’t want to purchase toxic carpet padding but I’m having a hard time finding a vendor that offers a wool/felt blend carpet pad. The Healthier Choice carpet pad seems like a safe – or at least safer alternative to rebonded padding.
Corinne Segura, Building Biologist
memory foam is higher in offgassing than other materials
Tina
Thank you again, Corinne! Just to clarify, the memory foam pad would be high in off-gassing compared to the polyethylene even with the UL GREENGUARD Gold & CRI Green Label Plus Certified? So, your recommendation is to avoid the memory foam in all cases? Thanks again!
Corinne Segura, Building Biologist
the certifications don’t mean much to me, there is a significant difference compared to polyethylene which has no offgassing. You don’t have to avoid it in all cases, it’s up to you, not everyone is affected by products with some VOCs.
Sam
So to clarify, mohawk smartstrand would be a good choice if you can’t do natural wool ? What kind of backing would you suggest with this?
Corinne Segura, Building Biologist
smartstrand is pretty good, not as good as air.o and homefresh. backings are at end of post.
MJ
Thank you.
What would be your best recommendation for a low pile carpet and padding for an elderly person using a walker or wheel chair and on oxygen because of lung concerns. Cost is a concern. Can you give both the best and also best healthwise and cost concern option. Thank you.
Nanette Knight
Do you know if Stanton uses moth-proofing on their wool carpet?
Thank you,
Nanette Knight
Corinne Segura, Building Biologist
All mainstream brands do as far as I know but youd have to ask them
mel large
Hi, So it seems that with wool carpets you have to choose between ones with permethrin – moth proofing or ones that use natural latex as the adhesive. Which is the lesser evil in your opinion? Thanks
Corinne Segura, Building Biologist
natural latex is not toxic so i dont have a problem with it in most cases, my only concerns are for people highly sensitive or allergic to latex as well as the fact that it doesnt seem that resistant to mold so id be concerned with it over a slab (even though there will be a vapor barrier put down first)
mel
thanks
Kaelynn Reid
Hey Corinne!
Followed you for a long time, thanks for everything!
Trying to make a long story short. We had Shaw carpet at the house we moved into three years ago. I used an at home carpet cleaner and while I did extract enough and it dried in time, but I feel like when I get my nose into the carpet it smells musty. We had a pro pull the carpet back and it’s definitely the backing that’s giving off the odor. I did get an air test done for mold which came back fine and weirdly there’s no evidence of water damage or that I over saturated anything. My question is, do I stick to the existing carpet that’s clearly off gassed and simply replace the padding underneath or is completely replacing the carpet and pad with the “middle of the road” nontoxic option (looking at Home Depot Natural Harmony as that’s what I’d be able to afford) a lower VOC/health risk? I couldn’t quite tell what your actual thoughts on the Natural Harmony was aside from it off gassing somewhat. Is the olefin/polypropylene in that blend an issue? Thank you!
Corinne Segura
I would not use Natural Harmony. If it’s only the padding that is smelling musty then I would only replace that.
Kaelynn Reid
Thank you!
Sharyn
I’m in UK and thought I’d finally found a natural fibre carpet that’s very low in VOC, sisal, but it seems to be only available with natural latex backing and has to be layed on recycled rubber crumb underlay.
is it worth giving up on sisal because of these? is the rubber a problem because of the rubber or what they stick it together with?
I can’t risk wool as I have a moth problem, I’m slowly getting under control but too risky to put wool down on the carpet.
Corinne Segura
recycled SBR rubber crumb is in the top two most toxic products to use in a home. the article on gym flooring goes into detail.
Sharyn
ahhhh thank you, I didn’t realise that the recycled rubber crumb was SBR.
I can’t find any recommendations of other underlays for under sisal carpet in your articles, is there any other option?
Corinne Segura
this article has a section on underlayments, there are quite a few good options.
Sharyn
hi, thank you.
I had a read of them, but not were saying OK for under sisal and in UK there only seems to be rubber crumb as an option.
wool is no good because I have a moth problem. the only PE foam I can find in uk is very thin for under laminate. there’s a wood pulp one but they won’t lay that under sisal.
I’m now discussing with a carpet company, putting the sisal carpet down without underlay. so hopefully that may work.
thank you
Julie

What are your thoughts on this carpet pad? Thanks for all your helpful information!

James Pratt
Bad news for those hoping to install the DMX 1-Step padding that you recommend. . Home Depot is out of stock for the forseeable future. I wrote to the company and just received a reply that they are having issues producing it in a timely manner. Ordering directly from the company (located in Canada) is the only option at this time. Shipping costs for those of us in the US are therefore prohibitive.

Paty Arias
Hello! Apologies, I posted my carpet question under a rug article. We have 20 yr old carpet in our living room that we would like to replace. We may be moving in 2-3 years, so I’m trying to find the healthiest option given the amount of time that the carpet will be used.
I’m considering Mohawk Smartstrand carpet with their synthetic felt pad in order to avoid polyurethane foam and memory foam. I’ve been in touch with Mohawk and they told me that their felt pad does not contain flame retardants, anti-microbials, rubber, or foam and that the range of total Voc’s for the carpet and pad is 0.5mg or less.
I’m trying to decide if I should go with this option, spend more and do a wool pad, OR abandon smartstrand altogether and consider something else. Any thoughts would be much appreciated!
Thank you!
Paty
Corinne Segura
Smartstrand itself has a little offgassing, the felt pad likely does not. Though I have not seen that exact padding myself. It’s very likely the same as their padding that comes with Air.o which is 0-VOC.
Paty Arias
Thank you, Connie! I finally got a response from Mohawk and this is what they said when I asked about the VOC level for the carpet and felt pad:
Range of Total Voc’s: 0.5mg or less
I think I’m going with Smartstrand, but I’m undecided on the pad. Would you go with a wool pad over the felt pad or does this not matter as much as the carpet itself?
Rose Blackie
Hello Corinne, Thank you for your blog – it was a very interesting read. I live in Queensland, Australian and I am looking to replace the carpets in my home I just bought. I am looking to use wool, perhaps a brand like Bremworth or Hycraft 100% wool carpets which is more commonly available over here? What are your thoughts? I was considering using a solutuion dyed nylon carpet but I am very concerned about the off-gassing and chemicals involved. I am just as concerned that the wool carpets form Bremworth and Hycraft could contain just as much chemicals with the pesticides and backing etc. Any help would be so much appreciated!
mel large
Hi, just wondering how you got on, I’m in NZ and having similar difficulties.
James Pratt
Have you tested and rated the various carpet padding adhesives? I need to find one to adhere rubber padding to concrete, and also preferably a product that is applied with a caulk gun.
Corinne
I mention the adhesive in the article. When you say rubber padding though, make sure you have tested that as some rubber is very high in VOCS.
Christy Siat
Can you tell me if Proximity Mills carpet is truly no or low VOC. I have read that it is, and the one store in the area that carries it also states that it is. What do you know about Proximity Mills and their VOC claims? Why is it so limited to only two retailers in the whole metropolitan area?
Corinne
I don’t see anywhere where it says their carpets are 0-VOC and they are nylon so I very much doubt that. Plus they list some of their vinyl as 0-VOC clearly on the website so if the carpet was 0-VOC I would expect it to be listed. There is a huge difference between 0-VOC and low VOC. but if you see one listed as 0 please drop the link. Sales people in the store are not a trusted resource if the company themselves does not say it’s 0-VOC.
Kim
Hello. Thank you so much for the article it has been very helpful as I search for new carpeting for our home. My question is about the mohawk smartstrand carpet. Do you have any experience or reports on how this carpet holds up in comparison to other carpets? I’ve seen mixed reviews. I’m wondering how durable it is common because I do not want to have to do this again any time soon! Thank you for your input.
Corinne Segura, Building Biologist
i don’t know, i mainly focus on what things are made of, you would have to check reviews for that. also the new PET or PTT carpets are somewhat new, at least they say they have improved upon older polyester styles which used to not be as durable

One of the standout features of a wool carpet, especially in a coastal environment like the Gold Coast, is its natural insulation properties. Wool is a fantastic insulator, helping to keep the room warm during cooler months and cool during the scorching summers.
Christina
Hi,
Thanks for the wonderful post!
Can you make a recommendation for a non-solvent based moisture vapor control sealer to use over concrete slab in a basement before installing carpet tiles?
I’m interested in the FLOR carpet tiles and just read on FLOR’s website that “It can also be installed over smooth, fully-cured (minimum 90 days) concrete floors. Concrete needs to be sealed with a non-solvent based moisture vapor control sealer before installing FLOR. These are typically polymer based (urethane, epoxy, acrylic) and designed specifically to control moisture emission rates of the concrete slab (internal moisture not topical spills).”
Thanks for your help!
Corinne
I don’t have a list of liquid vapor barriers for the slabs but id look for a 0-VOC one if possible like this however epoxy would not be my first choice. Acrylic would be better and lower in odor.
Christina
Thanks! This is great!

We moved into a wonderful apartment 1 1/2 years ago and I’m now feeling like I’m experiencing an Allergic Reaction to our carpet! I tend to have Chemical Sensitivities. My feet feel have a heated-up burning feeling now when I walk on it along with a rash. I would greatly appreciate any suggestions you have of something I can treat our carpet with, etc. Thanks SO MUCH !!

Did you ever test samples of the Engineered Floors DreamWeaver PureColor? You said in the article you were waiting on samples
Corinne
no I couldn’t get it
Amanda Aszman
I can’t tell you how many times I’ve referenced this page, Corinne, thank you. Regarding Empire Today’s HomeFresh carpets — have you Learned anything about their PUP pet urine protection? I did speak with someone knowledgeable at their company, who explained that these carpets have not had Scotchgard treatment for several years, they simply (unfortunately) have issues with the webpages not being correct/updated, and with outdated samples still being used/ given out. So I am heavily leaning toward HomeFresh, but I can’t find any information about what this PUP is. Wondering if it’s an innate benefit of the carpet or if it’s an added topical protection that I would want to avoid.
https://www.empiretoday.com/carpet/frieze-carpet-incomparable-sphinx
Corinne
it’s really hard to say if they don’t say. They could be referring to a plastic layer between the fibres and the felt cushioning so that urine doesn’t go below or it could be something to help liquids from being absorbed in the fabric. Since PFAS in carpet are about to be majorly limited by some states banning that in carpet it’s unlikely that they would be moving that way.
Bee
Hi Corinne, thanks for all the amazing work you do for all of us!
Do you have an opinion on Air.o carpet vs. SmartStrand (silk) now that it is possible to get the SS with the non-latest ReCover backing?
I prefer the looping in the SmartStrand, but want to buy the healthiest thing! And can’t go for wool because of wool allergies.
Also, are you consulting again yet? 🙂
Thanks again!
Bee
Non-latex backing*
Corinne
Air.o and home fresh are 0-VOC, SmartStrand is very low VOC, the backing won’t change that because it’s coming from the fibres.
Stephanie
Did you ever receive your samples of Engineered Floors DreamWeaver PureColor? If so did you have any conclusions?
Corinne

Hello,
I have a dog with arthritis and have installed an outdoor wooden ramp. Initially I had it covered with synthetic grass but after looking into the chemicals used I have decided to use carpet. Could you please recommend a safe outdoor carpet material to put over a wooden ramp? One that could stand up to rain and moderate cold and have some grip.
Corinne
some artificial turf can be fine. in terms of carpets or rugs I only know of the brands I mention in this article and the rug article
Jason
Empire homefresh advertises scotchgard on the samples the reps show

Took a photo of it
Corinne

Mike
Hi Corinne, just FYI I just found out Home Depot doesn’t offer the polyethylene carpet padding you recommend and that they sell for their installations.
The only offer 5 padding options for in home installation by their contractors and all 5 options are either a memory foam, a lifeproof “100% virgin densified prime urethane” or bonded urethane from Nike and Trafficmaster.
Corinne
ah interesting. It’s still for sale on their site but I wonder why they won’t use it in their home installations.
Mike
I was told it was because it’s not carried by the third party installers they use in my area. One would think they could just go pick it up from Home Depot. They wouldn’t even let me buy it and just have it at the house for the installers.
It’s incredibly frustrating but I may just use the lifeproof polyurethane cushion.
Besides being virgin material, in the Home Depot Q&A the manufacturer says it doesn’t include any chemicals listed under California Prop 65.

Corinne
are you sure that is polyurethane? if you’re chemically sensitive you will want to test this first whether it’s polyurethane or another foam type.
Pauline Wong
Hi Corinne!
I am a mom of 1 and hoping to have another soon. I am so grateful for your posts!
I have a Godfrey Hirst wool carpet, and need a carpet cushion/underpad….
Would you prefer:
1) Home Depot’s Lifeproof – Polyethylene foam
2) Healthier Choice – Polyurethane Foam, but GreenGuard Gold certified…how is this possible bc I thought polyurethane is a toxic material??
https://www.healthierchoice.com/healthier-choice-cushion-overview
You’ve said to choose polyethylene over polyurethane but the greenguard gold is throwing me off. My rep also mentioned Mohawk Smartcushion.
Many seem to have the Ultra-fresh built in antimicrobial…
What are your thoughts?
Thank you so much!
Pauline
Corinne
between those two polyethylene is way better.
Mike
Hi Corrine,
I’ve been having a terribly difficult time trying to find a safe carpet that lacks many chemicals. I found the Natural Harmony green label plus certified 100% wool carpet that might be a winner but now I’m worried about mold even with the Lifeproof polyethylene cushion.
Would it be better to go with a low/zero VOC PET carpet instead as I’m way more worried about long term issues with mold than short time off gassing?
Corinne
What are the conditions that would cause mold, is it on a slab?
Mike
I worry about spills over time, one of the carpets would be in a future kids room and another would be in a living area we would serve guests drinks.
I went to home depot to look at their wool carpets but they didn’t have any in store, only online. So I looked at their Home Decorators Collection and I found a really nice soft SD Polyester carpet that I’m leaning towards instead.
I’m sure it’s not the lowest chemical/VOC option but I could let it offgas for a week or two before moving in and Home Depot states their carpets are free of PFAS/PFCs, formaldehyde, Coal Fly Ash, added heavy metals and so on. I appreciate that transparency over my original choice for Home Fresh or Air.o as they have so many conflicting answers on using things like Scotchguard.
The only thing I’m worried about is if Solution-dyed polyester is significantly more toxic than stock-dyed polyester.
Mike
Oh, turns out the Home Decorators Collection carpet I have in mind is the solution-dyed polyester carpet by Engineered Floors with Purecolor. I did some research and see the whole carpet is made in a factory in Georgia as I was a bit concerned it was tufted in China.
Corinne
I like the Lifeproof from Home Depot which seemed very low in VOCs. Solution dyed does always seem to be the ones that are very low VOC. on the other hand wool won’t go moldy from spilling a glass of water once in a while. It will dry out.
M
We’re buying a house, the house is 5 years old. The stairs and upper floor(bedrooms) are carpetted. I don’t know whether it would be best for me to have the carpets thoroughly cleaned, or replace them. Initially my thought was to replace them, but I am struggling to find anywhere locally that sells any of the suggested carpet lines.
What would you do in my situation?
(I have moderate asthma, allergies, strong sense of smell (I banish new furniture to another room for weeks before allowing them near me for example). Allergic to latex.)
Corinne
If you don’t react to them you can keep the carpet you have.
M
My main concern had been whether the current one might have too much stuff up in it by now from people living in it, and people coming in for the viewings (think 12 families besides us viewed.) Do you think it’s common for there to be alot of stuff that’d effect someone like me in a 5year old carpet (no idea what type it is tbh, I only know the other floors of the house use LVP but atleast that’s had 5years to air.) So it’s weighing whether I will fair better with a new carpet or an older washed carpet. ^_^
Thanks for everything you do. <3
Corinne
You have to see how you do, I would be fine with it.

Hi Corinne, do you know if Dolomite from Earth Weave meets all criteria? Thank you! I read no VOCs, PFSAs or flame retardants, but not sure about mothproofing or the others. Thank you!
Corinne
You would have to ask about mothproofing if you’re avoiding that.
Andrea Koskamp
We recently installed the air.o New Beginnings carpet only on the stairs in our new house. I had gotten a sample and set next to my air quality monitor and it never seemed to be very high. It is however, preventing me from moving into the new house. I was curious if you had ever gotten a sample of the tape used to install it. Doesn’t make sense that the tape would be a problem, but it is one thing I did not test prior to installing. I haven’t found much information about it and am waiting for someone to get back to me regarding what was used. Thank you!
Corinne
I have not seen the tape for that carpet.
Brandon
Hi, when you say your top pick of the Home Depot options is lifeproof pet proof triexta – do you mean the 100% triexta or one of the blends (50/50 triexta and polyester)? I’m having a hard time finding a 100% triexta from them that isn’t high pile..
Corinne
the ones I sampled that I can track back to at this point were 50/50
Kimmie
Hi! Do you know if the felt padding underlay that you linked has added flame retardants? The person I am working with for installation asked Leggett and Platt and their rep said that they probably all have them per multifamily requirements
Corinne
I don’t have more info then what the company will tell us. But email them directly to ask them, not through reps.

Thank you for this post! We were looking at Mohawk Everstrand carpeting when I came across this. The sales person told us SmartStrand and Everstrand were not treated with anything (such as Scotchguard). I emailed Mohawk to ask about PFAS when I saw your post, and they said this:
Thank you for your interest in Mohawk Everstrand carpeting. As of Oct 1, 2019, no Mohawk soft surface products contain PFA’s.
Do you think I can trust these claims? I can’t seem to find any press release or report about them changing their manufacturing.
Corinne
Yes that sounds like an unambiguous message from them, I’ll try to confirm.
Dorothy
This is very helpful, thank you. I have a question about FLOR and Interface carpet tiles. It has “Intersept®
Protekt2®” That is some sort of antimicrobial and anti mold product. What do you now about it? When I try to get FLOR support to tell me more, I just get that they use it not what it is. Thank you in advance for any light you can shed on this carpet treatment.
Corinne
I don’t know if they won’t reveal it. But this sounds like two separate things. One part is their stain repellant which sounds like it’s not PFAS which is great. The second part is the antimicrobial which could be one of the following (guessing based on other brands): Pyrithione zinc, titanium, dioxide, Quaternary ammonium compounds, Potassium cis-9-octadecenoic acid, nano silver, or something else entirely.
Kimmie
Hi! Do you have a recommendation for a rubber underlay for a stair runner? My installer says it needs to be thinner than the typical carpet pads. Not sure what they typically use for this! Maybe your synthetic rubber rec for carpet underlay would work?
Kimmie
I guess it doesn’t need to be rubber but those tend to be thinner! Their standard is a “double set”sponge rubber pad so trying to figure out what questions to ask and / or what alternative to suggest
Corinne
I would avoid a dense SBR rubber.
Alton Broussard
I wish you wouldn’t use these abbvrevations. You’re TEACHING, correct? Many of your readers don’t know VOC. PFAS, PVC!! If I were to teach you to fly an airplane, you wouldn’t know ILS from VFR.
Corinne
It’s interesting how in order to make a suggestion/critique folks feel they need to yell and speak disrespectfully in order to be heard. I read all the comments on this blog, almost 5000 comments now and most of them are helpful in one way or another but it’s exhausting being yelled at when something could just be said normally.
Kelly
Thank you for all of the information, Corinne. I hope your readers can
appreciate what you’ve offered and be polite in their commentary.
Have a lovely day!
Corinne
Thanks Kelly
Barbara
Yeah, actually her readers do you
know what they are because we
are very allergic to them and that’s why we are here.
Also you can look this stuff up if
you don’t know what it is. And no,
she’s not here to teach!
She’s here to help us find
something good and SAFE, and thequicker she gets to it, the sooner
we can be healthy at home.

Keep in mind, with carpeting like the Mohawk Air.o brand, which I have in my house, it is extremely hard to vacuum. The different style padding underneath makes a stronger suction on the carpet. I have a good vacuum and even if I adjust some of the vacuum settings I can still barley push the vacuum. I really regret my purchase!
Os
I’m thinking of going right Mohawk smart strand for my basement but I’m A Little worried about the nano particles. Do you know if they can be absorbed through skin? Also any tips on keeping carpet mold free in a basement while not using too many harmful chemicals. We aren’t getting the super natural carpet because that would get moldy in a basement and I’m sure insects will love it too.
nicole
Hi Corinne are you aware if this item you listed may be a source of heavy metals like lead and antimony? or if any of the other polyester ones carry this risk?
https://www.flooringinc.com/carpet/tiles/ribbed-carpet-tile.html?sscid=c1k6_61n77&#!
Corinne
There’s no Prop warning on the website, where did you hear that it is a source of lead and antimony?
nicole
Thanks Corinne. I read that polyester carpets and rugs can be a source of antimony if new and if older lead as well…this was the post and on her site she says antimony in new.
https://tamararubin.com/2021/10/is-there-lead-in-your-vintage-synthetic-carpet-how-do-you-know-if-your-carpet-has-lead/
I can email you a picture of the screenshot where she talks about the antimony if you would like since I can’t attach here? appreciate your help.
Corinne
Ah yeah, the Ecology Center has tested new carpets in 2018 and found that some have low levels of antimony or lead. The lead is probably from fly ash but it used to be added as a stabilizer. Antimony is probably part of some flame retardants or a catalyst in producing polyester. The problem is the companies are not exactly forthcoming with what metals are in their carpets. It’s not just polyester though, it’s all synthetic carpets – nylon or polyester. They should have a Prop 65 warning on the sales page if it contains lead or antimony.
nicole
thank you Corinne! I appreciate your input
Stephen
Hi Corinne. My nylon carpet was installed 8 months ago with recycled foam under pad. There were many different issues with it and is now being replaced. It is being replaced with Natures Carpet medium green grade carpet as we found the Nylon to be too much off gassing. We avoided the 1700 square foot upstairs for 4 months until the smell went away after initial install. The nylon carpet was just removed today and the smell is back very strong coming from the under pad. I was planning to not change it. I thought the smell problem was just the carpet. Do you have an opinion with a brand of foam under pad called Healthier Choice. The company claims their foam under pad is the only one that is non toxic. The dealer I am using says it is very low in toxins compared to the recycled foam that I have now. I know wool pad is best but also pricier and usually thinner. I need at least 3/8″, preferably even 1/2″. Also I am allergic to dust mites and thought this would be easier to keep clean.
Corinne
I would not use memory foam (or rebounded polyurethane). Look at the ones I mentioned in the article.
Stephen
Thanks for your reply Corinne. I went down to home Depot to look at the lifeproof brand you recommended. It looks like a good option. I’ll ask Natures Carpet when I see them tomorrow. I’m in the Vancouver area where the head office is for
Natures Carpet. I mentioned the Healthy Choice brand as they recommend using it with their wool carpet. It’s claimed it’s very low VOC’s and doesn’t contain many of the other harmful chemicals. It is the only one that is Greenguard certified also. It is made with polyurethane which isn’t a good choice. This is very confusing with so many opposing opinions. And how it’s possible for Healthy Choice to make
these claims and being made with polyurethane. Thanks..
Christi
Are you just going off of your sense of smell? Or are you using actual numbers based upon testing done with an instrument that can detect these chemicals? I’m asking because I’ve used no VOC paints that were a lot smellier than those that weren’t low VOC. Whether something smells or not does not necessarily tell you if you’re detecting harmful chemicals. I wouldn’t trust my nose to detect everything. Please let me know how you’re determining which floorings are the safest.
Kelie
Hi, I just wanted to give an update on Mohawk Air.o carpet for anyone who is worried about Scotchgard.. I called Mohawk and spoke with their customer service on 07/20/2022 and they stated that the Air.0 carpet is NOT treated with Scotchgard. It’s possible it was before but that they have discontinued doing so now. If true, this is a big win for sensitive folks 🙂
cari
Hi, I just called Mohawk and they confirmed the Air.o is indeed treated with Scotchguard. Also, the Air.o samples at the store clearly indicated it’s Scotchguard-treated, the
logo is right on the Air.o sample specs. The retailer assured me that the samples were “new” and he said Mohawk would’ve come in with stickers to put over any info that has changed.
Corinne, I love your site, and THANK YOU so much for all your work providing a
roadmap through this complex and frustrating territory.
Corinne
ok working on trying to figure out what’s going on with them.
Corinne
OK so in my call with the technical department they said it’s not treated with Scotchgard and those are old samples. They maintain it’s free of PFAS.
Rene
Hi,
Thanks for your carpet advice, so helpful! I am looking at getting a wool carpet for my new home but I can only access two types of wool carpet (I am not in North America) that have moth treatments. Untreated wool is not available. One is treated with Permethrin and the other with Bifenthrin. I would rather wool than a synthetic carpet, as I feel that would be the least toxic option even with the insecticide. I would consider synthetic but it just feels it would have more nasties in it. I am basically now trying to chose between the least nasty moth treatment applied to the wool carpet. Do you have a view of which of these two insecticides is worse? Thanks so very much for your assistance!
Felicia
We have several Mohawk dealers in my area (Northern VA) , so I decided to check out the Air.o, since apparently there is no odor and it seems to meet my needs. To my surprise, none of the Mohawk dealers I talked to had even heard of it. I also can’t find a way to contact Mohawk when I looked at their website.
Melissa
Hello Felicia, I am also in Northern Virginia and looking for Air.O carpet as well.
Were you able to find a Mohawk distributer ? If so I would like to know where you found it.
Thanks!
Cara
Hi, my mom is 80 with COPD( chronic lung condition). She was supposed to get her wool carpet installed today with what was supposed to be safe padding….. according to the carpet guy. She went over there to check it out and it was full on foam padding, probably recycled, and rebonded….It smelled horrid. She had the installer stop. We had to postpone the movers, etc. Dear Lord.
We are not sure what to put in. It’s two weeks to get a wool padding….but we can get a synthetic felt right away……..Will the synthetic felt be really bad? Is it any better than the foam?
B
Hi Cara,
I saw your comment. I’m in the same situation with a family
member. I need find the least non toxic
carpet etc… Have you had any luck? If so, is there a way we could connect? Thanks
Amanda
Thanks so much for your post, it’s so helpful!!! Have you heard of Kaleen’s new pure life line of carpet? They say it’s wool and non toxic but would love to get your thoughts.
Jamie
I have same question! Kaleen or Unique Carpet non-dyed wool?
Corinne Segura, Building Biologist
kaleen pure life looks good, but i cant do a full product review in the comments
Cher
I have the same question about Kaleen’s Pure Life. I couldn’t find any third-party testing or verification. One thing I don’t like is that Pure Life is the “clean” brand within a company of traditional carpets. So this company, Kaleen is not making it it’s mission to provide non-toxic goods, it’s just trying to capture that audience in addition to their traditional customers.
Corinne Segura, Building Biologist
I’ve added them to the post finally!
Simone Reyes
Thank you. I’m hoping to find someone to hire someone to replace ( since I can’t seem to find any comfortable ones online ) all the cat trees / condos in my house. The smell is awful and I’m worried and upset I didn’t do this earlier. The problem i am having is places like Empire Today only do installations and don’t sell the home fresh carpet. I need to use synthetic but not sure how to go about this. Any ideas ? Thank you
Simone
From Mohawk
Thank you for your interest in Mohawk. Unfortunately, we do not sell direct. The Air.o carpet can be purchase from a Mohawk retailer in your area. Let the retailer know the size of the carpet piece you need and he/she can give you an estimate and place an order if you wish. The Air.o carpet can not be manufactured with a special run without Scotchgard applied. All Mohawk carpets are Green Label Plus certified. Green Label Plus certification testing is performed on products after any stain protection has been applied. You may find Mohawk retailers in your area by calling 800-266-4295 or using the store locate feature at http://www.mohawkflooring.com. Thank you again for your interest in Mohawk.
Caryl Brown
I really appreciate your research!. I am trying to replace my carpet and found the MOHAWK New Beginnings 2
But it is made from recycled plastic and supposed to be VOC free.
Just confirming that this is the same as your 1st pick!?
It’s been so difficult to decide, I was just thinking about keeping the existing 25 year old carpet. Now that you mentioned mold spores….. there are some black spots and dirt that will not come out after cleaning…. What should I do!!?? Its a small room….
PLEASE email back your thoughts! AS I probably won’t be able to find you again! THANK YOU!
Cbrown1340@aol.com.
Corinne
That is part of Air.o
Simone
What about the scotchguard ?
Katrina
Hi Corrine,
We are finishing our basement (cement floor). I went with wool carpet and felt padding to eliminate toxic chemicals (we have young kids). The carpet installer came and to my shock, used Taylor 720 padding cement to glue my felt pad to the cement floor. I understand, that’s as bad as it gets from toxicity view point. I feel like all my efforts to keep our floors non toxic went out of the window. Do you have any recommendation for non toxic pad glue? I really don’t know what to do at this point. Any ideas would be appreciated.
Christine

Jorjia Blom
Hi Corinne. We are living in a rental with light coloured wall-to-wall carpeting on the stairs and top floor. No problems with off-gassing, but the carpet is now looking dirty despite regular vacuuming, and we have to clean it. We absolutely want to avoid any mould formation from carpets not drying out in under 24 hours, and to this end , we are thinking of the Hoover Smartwash Carpet Cleaner (FH52001), as it has a heated drying feature, not just an extractor. Do you have any thoughts about this, or alternative suggestions?
Corinne
I haven’t looked into that one.
Donna P.
Hi Corrine,
What do you think about Ruggable washable carpets? I wrote and asked about the carpet contents (100% polyester) and they wrote, “Our low-pile and lightweight Rug Cover is stain-resistant, water-resistant, and designed to fit conveniently in your home washing machine—even the 9×12!” They also state, “The rug pad is made of polyester (95% recycled fiber). The Cling Effect™ texture is created by heating the surface (think Crème Brûlée dessert). The nonslip backing is made of Thermoplastic Rubber (TPR) a latex-free synthetic material that is commonly used in yoga mats.”
Corinne
I would use those
Jessica Katz
Hi! Great article, thank you. Can you explain more about why you would use Ruggable?
Corinne
The blog is first and foremost for people with chemical sensitivities. When I hear from folks who are extremely sensitive that they did well with a product that is something I will list. The section on plastic rugs is based on that. The only exception would be if the product was tolerable for the chemically sensitive but contained a significant amount of a toxin that has no odor and that folks don’t react to in the short term like lead.
sylvia
what do you mean about the exception? are you saying if chemically sensitive folks tolerated a product but it was highly toxic you wouldn’t list?
what do you think about the Ruggable rug pads?
Laura D
Well you are just wonderful! Thanks for this life- and home-saving advice! I became MCS when spray foam install went wrong in my home reno and have a staircase with no carpet for a year while we’ve been trying to make the house habitable.
I want to buy you cups of coffee but when I try it just says “go back” under where you would pick how to pay. I’ll watch for a response. Thank you again!
Donna Vogel
Hi Corinne, I need to carpet my stairs. Would any of the carpets above work on stairs? I wish I could afford to do the stairs in hardwood like the rest of my floors but that is not in my budget yet. Thanks! Sending a coffee your way. 🙂
Corinne
Yes most will work on stairs. Not the shag ones though, and not FLOR. But with the one you like just check with the company.
Mira
Hello! Since you know so much about chemicals in carpets, I wonder if you could give me your opinion on olefin fabric for couches. Is it toxic?
Corinne
I don’t consider olefin to be toxic at all but the fabric treatments can be.
Steve
Hello– I’m installing carpet in a small basement and trying to figure out what would be a good non-toxic carpet padding for it. The store is insisting that I use Karastep and claim it’s green label plus certified. I know that certification isn’t meaningful, but is there a type of pad you’d recommend for a basement setting? I know carpet in a basement isn’t ideal, but it’s our only option right now due to other factors. Thanks!
Brandon
Everstrand does have scotchguard. Smartstrand does not. I have verified. “On the other hand, Mohawk EnviroStrand was not as good, it was more like a conventional carpet odor in my experience, despite also being solution-dyed PET. It also does have Scotchguard, unlike EverStrand and SmartStrand.”
Barbara
Hello,
I just purchased an area rug and runner by Everstrand, and there is an odor, although this is a PET rug. Any suggestions? I didn’t think there would be harmful chemicals, so what would contribute to the odor? Would a product like Smelleze be an option?
Great site,!
Corinne
Yep Everstrand has an odor, that’s why I listed it as not as good as the others.
Joy Swanson
You have an important typo. You reference Air O as your top pick under the Home Fresh sub-heading making it confusing as to which brand is actually your top pick. Just FYI.
Corinne
thank you!!
Brandon
Also, are you talking about smart strand and smart strand silk?
Corinne
I sampled both, they seem the same to me (in terms of chemicals).
Kru
Hi Corrine
Thanks for the very informative post. Like others in the UK it’s proving extremely difficult to find a low VOC/chemical never mind a VOC/chem free carpet over here.
Have you heard of NuSilk by a company called Sylka? They are the only ones from all those I’ve contacted that have supplied a VOC certificate and have told me their carpets are entirely formaldehyde free.
Other than that the next best option I’ve found (besides the natural/untreated wools) are the plant fibre ones but these shed a lot and some are quite rough to touch so not very soft – not very practical overall depending on the application.
Thanks again 🙂
Corinne
PET and PTT carpets have been far lower in offgassing than nylon from all the brands I have seen. I would start there.
Bri
If you wanted to install Earthweave wool carpet over a concrete slab what would be your choice for padding? The earthweave padding is so pricey and I can not find it in stock!
Leaning towards the synthetic felt pad you linked here-fibertek Are there any chemicals in the synthetic felt that would be concerning? Or would the dmx polyethylene padding be better over concrete? Thank you!!!
Corinne
I wouldn’t put any carpet pad on a concrete slab. They are either prone to mold or they block moisture which often causes mold underneath.
Bri
Would any of those carpet pads I mentioned have the greatest impact on helping even to reduce the chance of mold growing under the carpet? The polyethylene?
For kids rooms, we are wanting carpet so they can have a cozy place to spread out and play on the floor. (It’s Lego town galore here!) I understand the mold issues with a slab foundation but I just don’t think tile or polished concrete is a good option here.
Corinne
It would ideally be something breathable and not be make or organic material.
Hillel Abrams
Any non-toxic recommendations for covering a 30ft ADA outdoor ramp? Both myself and my elderly dog use the ramp (I am not in a wheelchair), but the aluminum can get very hot for the dog’s pads. Most artificial turf (rubber backing or not) is highly toxic, so I am looking for alternatives to that. Thank you for considering this request.
Phill Weaver
Hello Corinne-
You commented that you “have seen a vapor barrier over a concrete slab become a mold risk in most homes.”
I am confused. I thought a vapor barrier or concrete sealant would eliminate moisture coming up and therefore reduce the possibility of mold.
Corinne
You often see or smell mold and bacteria festering under the vapor barrier, in my experience. Cheryl Ciecko architect talkes about this more.
Helen
Hi Corinne,
Your article is incredibly helpful – thank you so much.
Do you have any recommendations of no/low VOC carpets available in Europe ? We live in London, UK and are having a hard time finding suppliers of carpet free of PFOAs, permethrin and phthalates.
We have contacted Mohawk and are awaiting their reply.
Do you know if Smartstrand technology from Mohawk is the same as Smartstrand from Lano (a company in Belgium – who say they use nano technology in their low VOC Freedom carpet though are unwilling to tell us what their carpet and backing are actually made of ! ).
Thank you 🙂
Corinne
Just keeping up with all North American brands is a full time job, so I’m not sure about that.
Kru
Hi Helen
Did you ever find anything suitable? What did Mohawk say?
I found a brand called Sylka who use a proprietary version of Nylon called NuSilk and they are the only ones so far that have sent me a VOC certificate. it seems pretty low on all counts but I have to admit some of the info is beyond me. They’re also very expensive starting at £125+VAT per m2!!
Thank you. 🙂
Bob
HI,
Did you manage to find anyone that stocks a carpet to your requirements?
I am looking at a 100% wool carpet from Brockway carpets which is undyed and untreated. The only issue I can see if that they use SBR for their backing material, and they don’t have an official VOC report, but the one they shared was not tested for formaldehyde :/
Thanks.
Robert Hogward
Thank you so much this information was certainly helpful. Carpet is for comfort and to prevent slippage. It also minimizes the noise.
Corinne
You’re welcome Robert.
Betty Smith
Wanted to put a 3×5 rug on each side of a queen bed, with the feet under each rug. Easier to clean and your not paying for so much rug Under the bed which is harder to clean. Would this be a good idea?
Much appreciated
Dorothy Casura
Hi,
I suffer with Environmental Illness / Multiple Chemical Sensitivity. In the past I have been given a couple of cat trees that had synthetic materials used in the making. Due to the age of the trees, i had no problem with outgassing. I need to rebuild / recover one and figure to do both trees at one time.
I want clean materials: the rope and the carpeting. Where are sources of carpet pieces and rope that is organic? I don’t want to play around with toxicity at all with the recovering materials!
Thank you
Corinne
This post lists all the brands of carpet that are non-toxic or less toxic.

I wanted to put a rug in each of my bedroom closets that could only accommodate a 22″ x 6′ rug which is not a manufactured size. What would be the best option to protect my solid wood flooring in the closets?
Mary
I am looking for information about Durahold carpet pads – are they a good green option in terms of low toxicity?
An
Hi Corrine! I was so relieved to find your post on wool carpets. We have been in search of a safe carpet option and after visiting several stores in the bay area, we were thoroughly confused with the number of options and types available. I am learning to read their certifications but constantly get backtracked as whenever we ask the salespeople about them, they tell you a new story about the certifications or lack thereof – it is difficult to discern whom to believe.
We recently saw a small stock of wool and wool combination carpets at a store and some had a CRI certificate (in addition to the floor score, green council, etc). When we asked the salesperson about this he said the CRI is created by the people who’ve earned the certificate and so it is not a real mark of quality. Is this true?
Further, he mentioned that wool carpets are very difficult to clean and that you cannot run a normal Shark or Dyson floor vacuum on it as the wool fibers get shredded. His recommendation (contrary to the Maintainance documents for Earthweave, etc) was to only steam clean, which sounded very impractical to us. Could you shed light on the best practices to keep wool carpets clean?
Another recommendation – to buy a pure material carpet (i.e. either wholly wool, or nylon), but not a mix as the cleaning for each component thread should ideally be different, but when they are mixed together in a carpet, it leads to suboptimum cleaning results. Is this true ?
It would also be really informative if you could write about the different industry certifications in this space and which are the one’s to be sought out. Thank you so much for sharing your knowledge on this!
Corinne
Hi! I don’t find CRI useful at all, every carpet can meet that. Here is my post on certifications https://www.mychemicalfreehouse.net/2020/12/what-green-certifications-mean-for.html
Lori
Can the Empire Home fresh be tacked down as you mentioned. I would really like to get the Empire home fresh but I cannot put double-sided sticky tape or glue on my wood floors. If it can really be. Tack down I would like to know.
Corinne
They said tacked down or taped down, but it’s hard to get a lot of info out of them without doing an in-home estimate.
Harley
Just had Empire Home Fresh Non-VOC installed – USF Incomparable Sphinx. It was taped down with wide double-sided tape. Problem is we can’t find any cleanup instructions for accidental spills specific to that type carpet. Also, we achieved a much better appearance by first removing bull nosing so carpet was measured/cut to base boards. Then added new bull nose atop carpet
Corinne
thank you for sharing that about the tape. You can look up cleanup for polyester carpet more generally.
Jody Hunter
Carpet can be installed in your bedrooms, stairs, etc. In my years as a carpet installer, carpet is usually installed on stairs. Some of my clients have kids or live with elderly people.
Kristen Harte
What would you suggest for someone who has mild asthma/allergies? Is wood OK.
Builder initially put in wall to wall over a concrete slab 21 years ago…do not know if there is something between the concrete and the rug.
Thanks so much. I love the wool.
PS I so appreciate your vast knowledge on the subject!
Corinne
You should get a sample to test for allergies.
Nerissa
Hi Corrine! I have carpets already in the home we bought a couple of years ago and I’m wondering how I can have it tested to determine if there are PFAs on it or not – I’m in Canada- any suggestions? Ty SO much!!
Jorjia
We moved into a rental with (conventional) light-coloured carpeting, and though we vacuum it regularly with a hepa-filtered vacuum, we need to find a way to clean it. Is steam cleaning the best option for those with chemical sensitivities and dust and mold allergies? If so any steam cleaners you recommend?
LaTanya Cox
Hi, I’m looking for a flooring for my childcare center that is economical, safe/healthy for children, free of VOCs, Phthalates, or other harmful chemicals– which would include any adhesives that are used for installation. Can you help me? I know I’m asking for a lot.
Corinne
Check out the main flooring post, you also have to consider your subfloor, budget, and how durable you need it to be. https://www.mychemicalfreehouse.net/2019/09/zero-voc-flooring.html You can always set up a 30 min email consult here if that would help https://www.mychemicalfreehouse.net/contact-me
Lauren
Hello Corinne,
I am currently looking for a 100% wool carpet, and have found ideal options which have no mothproofing, no chemicals, etc. (thank you for your advice!)
There’s an option to add Intec stain protector on top – I’ve emailed them and they’ve said the below:
Intec SI is a micronised emulsion of reactive siloxane molecules.
Intec SI does not contain any residual cyclomethicone’s ( D4, D5 or D6) or any SVHC substance or PFOA.
Intec is waterbased, so it does not release any VOCs in use.
http://www.intecprotector.com/carpet_protector.htm
I would like stain protection if it’s safe – as the carpet colour will be light – but NOT at the risk of undoing all of the good effort of finding a healthy carpet in the first place!
Do you know if this protection is safe?
Kru
Hi Lauren
How did you get on with your project? did you ever find out if Intec is any good?
Thanks
Douglas Glassford
Hi Corrine
I have experienced some health problems which seem to be caused by carpeting in the homes where I have lived recently and which seem to have affected the screed to concrete floors.
After lifting the carpets, I found that the ‘rubber’ underlay was very old (40+years) and the odour appeared to be coming from this rather than the carpets.
Lifting and removing the underlay / carpets from the ground floor rooms reduced the noxious smell but the screed still smells after cleaning with a variety of agents. When the temperature and humidity in the house are low, the problem is negligible. However, when both are elevated the smell returns strongly and, if a bedroom is not well ventilated overnight, I get gastritis.
There is no problem with areas of the house where floors have been tiled. Nor do I have any problem when I stay in other carpeted homes. Is the leaching problem known to you and / or is this something you can provide advice? If not could suggest someone who might be able to help?
Kind regards
Douglas Glassford
Corinne
I would have to look at this in person to figure out what was going on there. I have heard this from others. It could be an interaction between different compounds or it could be moisture coming up from below causing mold and break down of the foam.
Douglas Glassford
Many thanks for your reply Corrine. Unfortunately I am living in the UK. I am sorry that others are having similar problems but it is reassuring to know I am not alone! If I do get to the bottom of this I will let you know.
Kind regards
Douglas

Hi Corinne!
I’m not sure if this is an appropriate place to ask a question or if I need to set up a consultation, please let me know! I am currently looking for carpeting for a house that I won’t be in more than 2-3 more years. However, I need to replace carpet in an upstairs with 3 bedrooms, hallway, and stairs. I’ve found a carpet called Triexta at Home Depot that claims to be non-toxic. However, my research shows it is made of : “Triexta is a synthetic carpet fiber made from polytrimethylene terephthalate, which has some similarities to polyester.Sep 17, 2020” Do you know anything about this? Thanks so much for this resource!!! Hope you are well in these uncertain times 🙂
Corinne
I would need to see it in person to really compare it to the others. I don’t see much info other than CRI certificate which they all have now!
Eric Miller
Your advice is what I have been looking for – moved into a rental studio with ‘renovated’ floor which I think is called vinyl plank tiles and though there was a bit of order, it was not as bad as many apartments which now reek of this stuff. But I wish I could seal off the odor that still emanated from it. Is the carpet seal on your website usable on this vinyl floor:, or is there another product? Cannot change the floor as it’s a rental, but could apply something, I would think, while I’m living here. Do you think if I got one of the nontoxic rugs on your website that might ‘cover up’ the odor? Appreciatively, Eric
Corinne
In the post on remediating offgassing there are options but in a rental those won’t be acceptable. I would do something temporary.
