I have messaged and talked to every company on the list so you don’t have to.
I will also explain the main chemicals of concern found in toaster ovens and what a Prop 65 warning really indicates after the list of toaster ovens.
My list of favorite non-toxic toaster ovens meets the following criteria (which is based on my opinion):
- Are free of per- and polyfluoroalkyl substances (PFAS).
- Are made with stainless steel bodies.
- Food contact areas are stainless steel or chrome-plated steel (or could be replaced with stainless steel items easily).
- If a food contact area is made with uncoated aluminum or a non-stick surface, it will be noted (as you might choose to avoid that model or replace that part).
- I will note if it carries a Prop 65 warning (though this is not a great indicator of real-life exposure to harmful chemicals in many cases).

Non-Toxic Toaster Ovens
1. HYSapientia
This is a good pick because the backing tray is enamelled iron.
Functions: HYSapientia Air Fryer Convection Oven has the following functions: air fry, grill/broil, bake, dehydrate, thaw, rotisserie, toast, fish, pizza, and steak.
Materials: HYSapientia air fryer oven is made of stainless steel on the outside and galvanized steel on the inside.
Since this has come back into stock, they have changed a few things. The crumb tray is galvanized steel, the baking tray is enameled iron, and the baking rack is chrome-plated iron.
I have contacted them to confirm the materials in this enamelled iron, as I’m not clear what that is made of.
Prop 65 warning: No
Price point: They have two sizes, both under or around $150 on Amazon. It is also available at Walmart.
2. Midea
A top pick, though there is conflicting info on what the baking tray is made of.
Functions: The Midea Flexify French Door Toaster Oven has the following functions: Air Fry, Roast, Bake, Broil, Toast, Pizza, Reheat, Slow Cook, Dehydrate, and Warm.
Materials: Interior Lining or Coating: The oven does not include any non-stick coating. Cooking Tray and Basket Material: The cooking tray and basket are made of stainless steel, said one rep.
The website only declares metals in the cooking tray, but one reader said the manual instructs not to damage the non-stick coating on the baking tray, so it’s not 100% clear what the baking tray is made of. There is no explicit declaration of PFAS.
Prop 65 Warning: Yes
Price point: Under or around $150.
3. BLACK+DECKER
This is the top pick in the low-cost category, but to meet all of my criteria I would replace the baking pan with a stainless steel version.
Functions: The BLACK+DECKER Extra Wide Convection Toaster Oven (8 slice) has the following functions: Bake, broil, toast, and keep warm.
You can bake lasagna, brownies, and even 12″ pizzas in this larger true convection model.
Materials:
The exterior of the body of Black+Decker toaster ovens is stainless steel.
All the interior sides of the Black+Decker toaster ovens are made of stainless steel with a zinc coating.
The rack is stainless steel (though it might be chrome-coated which is also safe, they were not that clear).
The baking pan definitely does not have a non-stick coating and is aluminum, they said on the phone (but they weren’t 100% sure about that part).
If you want to buy your own 10″ or 12″ stainless steel baking pan, this one looks good (though you might want to measure the one that comes with it first for the best match).
See all the Black+Decker toaster & convection toaster ovens here.
Prop 65 warning: Yes, the company confirmed that their toaster ovens have a Prop 65 warning for styrene and BPA in the cord. The rep advised washing your hands after handling the cord.
Price point: Under $100 on Amazon
4. Oster Digital Air Fryer Oven
This is also a top pick, though if you want to avoid raw aluminum in food contact areas, you would have to replace the pans and trays.
Functions: Oster 10 Function Air Fryer Oven, Toaster Oven can air fry, bake, broil, defrost, dehydrate, pizza, roast, tender roast, toast and warm. Fits a 12-inch pizza
It goes up to 450℉.
Materials:
A rep says:
Its interior design is made up of galvanized steel or aluminized steel which makes it easy to clean and is safe.
The baking pan, broiling pan, and tray are made of aluminum without a non-stick coating.
You may choose to replace these pans/trays with a stainless steel option (like this one, but I would wait until you buy it and measure the size of the baking pan that comes with it) since aluminum can leach into certain foods with enough contact time (though it depends on the type of aluminum and I don’t have that kind of detailed information from them).
The air fryer basket and wire rack are chrome-plated steel, which is safe.
There are only very minor plastic parts on the exterior.
Prop 65 warning: Not posted on sales pages, but a rep said it does have the warning.
Price point: Under $160 on Amazon
5. Hamilton Beach Countertop Toaster Oven
A relatively small and inexpensive choice. Like with some of the others, my preference would be to replace the aluminum baking pan.
Functions: The Hamilton Beach 6 Slice Countertop Toaster Oven With Easy Reach Roll-Top Door has bake, broil and toast functions.
As a toaster oven, it fits 6 slices of toast, a 12″ pizza, or a 9″ x 11″ baking pan.
It goes up to 450℉.
Materials: The interior cavity is made of galvanized steel.
The oven rack is made of chrome-plated steel.
The mesh basket is made of chrome-plated steel.
The baking pan is made of aluminized steel. If you want to replace the baking pan with an all stainless steel option this one comes in various sizes.
This appliance does not feature any non-stick coatings.
Prop 65 warning: I don’t see one listed on sellers’ sites.
Price point: Under $100 on Amazon
6. GreenPan Bistro Oven
I use GreenPan frying pans myself, I think their “ceramic” coating is green enough. There is no exposed aluminum, but the accessories are coated in their ceramic coating.
Green Pan Bistro Air Fryer Oven has the following functions: Bake, broil, air fry, proof, dehydrate, slow cook, toast, warm, and pizza.
Their non-stick coating is not nano or PFAS-based but is silica/ceramic (see the composition here).
They use a stainless steel rack and air fry basket, and aluminum baking pan coated with their non-PFAS ceramic non-stick coating.
The crumb tray is not coated.
No recycled plastic is used on the exterior they said in an email (though the exterior is mostly stainless steel anyway).
Prop 65 warning: no
Price point: Under $200 on Amazon.
Other options that were on other bloggers’ lists:
The Emeril Lagasse Air Fryer Toaster Oven might contain PFAS coatings, specifically, they sent this document about PTFE in one email. In other emails, they said it has no coating. It wasn’t clear, after many emails with the company, where the PTFE is.
Regarding KitchenAid KCO211BM I could not get passed the canned responses. They said “the material is not DuPont Teflon, PFTE, or PFOE, and is not harmful to birds.” They did not say it’s free of all PFAS.
The Galanz Air Fryer Toaster Oven has a non-stick coating which is Teflon, a rep said on the phone.
Cuisinart – they have PFAS, though it’s not clear if they are just used on the baking tray (which can be replaced if you wished).
Our Place Wonder Oven – The food contact surface coating on the baking tray is their ceramic coating, the air fry basket and wire rack are chromed steel (safe), and the crumb tray is stainless steel. They said “While there are nano-sized raw materials in the liquid state of all sol-gel ceramic coatings for our nonstick ceramic, once they are cured and hardened, these particles cannot break free. There is no possibility for nano particles to leach into food while cooking.” I guess that is assuming the coating is not damaged nor does it leach. Using nano-metals in the coating does worry me personally. They did not respond to whether they use recycled plastic parts on the exterior, however, there are only very small plastic parts on the exterior.
More air fryers can be found here (along with more info on Antimony in air fryers).
Chemicals of Concern in Toaster Ovens
1. PFAS
Toaster ovens oftentimes contain non-stick coatings on the inside which are made from per- and polyfluoroalkyl substances (PFAS).
These chemicals are referred to as “forever chemicals” because they don’t break down inside your body or in the environment (source).
But is there a risk of exposure in toaster ovens?
When PFAS like PTFE coatings overheat, “they can produce fumes that are deadly to small birds and may be harmful to humans as well”.
This is a real-life “canary in the kitchen,” says Graham Peaslee, PhD, a professor of physics, chemistry, and biochemistry at the University of Notre Dame who studies PFAS.
So what is overheating?
Dr. Peaslee explained in an email that “Teflon/PTFE starts to decompose at about 500℉ (260°C). It releases gases at these temperatures that will kill small birds and cause something called “Teflon flu”. These gases include a fluorinated version of phosgene – the WWI mustard gas component.”
“Other PFAS behave differently than PTFE (Teflon), but many will evolve as gases and become inhalation hazards,” says Dr. Peaslee.
Most toaster ovens reach 450℉ max, so depending on what PFAS was used, this might not be a risk to the person using the oven.
I prefer to avoid this chemical in toaster ovens, which is based on the risks to humans and the environment. All models listed will be free of PFAS (according to the manufacturer’s information).
Environmental Risk
Dr. Manjunath explains that even if the PFAS do not become gases in the oven, there is still a concern about the use of PFAS during disposal.
Certain PFAS have been identified to persist longer in the environment than any other synthetic substance. PFAS tend to contaminate groundwater and drinking water.
Moreover, specific PFAS have the ability to accumulate in living organisms such as humans, animals, and plants, resulting in toxic effects. Some PFAS have been identified as reproductive toxins, carcinogens, and endocrine disruptors (ECHA).
Other Risks
There could be a risk of exposure if the coating is chipping of wearing down. I would avoid using acidic cleaners like vinegar as well.
2. Flame Retardants
According to the Prop 65 website, flame retardants can be added to the plastic components of appliances. (Source)
Antimony Hydroxide is a common flame retardant in cords.
Flame retardants of various types can also be a contaminant of black recycled plastic electronic waste.
My list of toaster ovens focuses on stainless steel models with very minor to no plastic on the ouside.
Children are at a higher risk of experiencing the negative impacts of flame retardants while developing.
Also, their tendency to engage in hand-to-mouth behavior and play near the ground increases their chances of coming into contact with harmful flame-retardant chemicals which leach out from appliances into dust.
There are concerns about potential neurodevelopmental effects in all individuals, says Dr Manjunath (NIEHS).
3. Non-Stick Ceramic Coatings
“Ceramic coatings” can be made of a sol–gel ceramic, which has a Si–O–Si (siloxane) polymeric structure (source).
Based on the testing that we have so far, it also seems that ceramic non-stick coatings contain various metals. F
or example, Tamara Rubin’s XRF testing of a ceramic-coated frying pan tested positive for the following metals:
Lead: 34 +/- 6 ppm (safe according to all standards — but not negative, she explains), Chromium: 7,837 +/- 284 ppm, Tin: 23 +/- 6 ppm, Platinum: 206 +/- 26 ppm, Zinc: 1,789 +/- 45 ppm, Copper: 4,965 +/- 87 ppm, Nickel: 615 +/- 41 ppm, Iron: 7,795 +/- 196 ppm, Manganese: 480 +/- 148 ppm, Vanadium: 1,039 +/- 230 ppm, and Titanium: 37,700 +/- 900 ppm. (Source).
Another brand of frying pan with a ceramic coating tested positive for Barium: 1,220 +/- 200 ppm, Chromium: 126 +/- 59 ppm, Antimony: 66 +/- 40 ppm, Iron: 2,361 +/- 177 ppm, and Titanium: 51,900 +/- 900 ppm. (Source) (And here is one more “ceramic” coated pan that tested positive for similar metals).
Some brands use nano-metals and others are free of nano-metals.
None of these metals would become a gas at 500℉.
However, not all brands with a ceramic non-stick coating are the same.
One brand, GreatJones for example, is not free of all PFAS.
So I would make sure, if you are avoiding PFAS, that you check that your ceramic coatings are free of PFAS.
There are some considerations related to potential toxicity, says Dr Manjunath. Ceramic cookware can contain Lead, Chromium, and Antimony in their substrates.
If the ceramic coating is in contact with food, it is possible that metals could leach out, though we don’t have full disclosure on what metals each brand’s ceramic coating contains and leaching tests to see how much they leach.
4. Aluminum
Some trays and pans in toaster ovens can be made of aluminum.
This is especially relevant when cooking wet, acidic foods in uncoated aluminum.
“This is particularly to be avoided since they cause more of the metal to leach into the food than dry, non-acidic items.” (source)
However, aluminum cookware that has been anodized or clad in a non-reactive metal such as stainless steel or a non-stick coating, does not leach into or react with foods. (source)
While some studies suggest that cooking in aluminum utensils or using aluminum foils is not harmful, other studies suggest it may lead to toxic levels of aluminum in humans (all those links are here).
It is important to note that toxicity concerns become more relevant in certain individuals (source).
This same study states that leaching was negligible, and so is the risk to human health, when using hard anodized aluminum utensils.
They also recommend the items should be washed with soft materials, not metallic scrubs to maintain the coating. A third way to mitigate risk is not to cook with aluminum at high temperatures.
I will note if the toaster oven has any aluminum parts that are in contact with the food. However, it was not possible to find out from the companies if the aluminum was anodized or contained another protective coating.
5. Prop 65 Chemicals of Concern
What is Prop 65?
Proposition 65 is a warning label for Californians about significant exposures to chemicals that cause cancer, birth defects, or other reproductive harm.
Any product that is sold in California will have this label even at retailers outside of California.
The list contains naturally occurring and synthetic chemicals. It is updated yearly and there are currently 900 chemicals on the list in 2024.
All toaster ovens will have at least one Prop 65 chemical. I would not avoid brands due to this label myself, due to the fact that the exposure limit is often not assessed.
Exposure Limit?
Technically this label is for “significant exposures” and the chemicals need not be listed if “the exposure is low enough to pose no significant risk of cancer or is significantly below levels observed to cause birth defects or other reproductive harm.”
However, in reality, the exposure risk is not usually calculated and you will still see the label if the product contains only trace levels of the Prop 65 chemicals or even when the chemicals are enclosed within the product and there is no reasonable way to gain exposure to them.
Are Companies Adding This to Everything?
It does seem like there are companies that add this to all their products even though they might not contain a chemical on the list, if the exposure is extremely minimal, or exposure is not expected with regular use.
There is no penalty for providing an unnecessary warning.
Toaster ovens will contain one or more of these Prop 65 chemicals, but mostly in their internal parts. I will note if the appliance carries a Prop 65 warning.
I will not be making a judgment on whether it’s a significant exposure.
Which Prop 65 Chemicals Can Be Found in Appliances:
1. Phthalates: may be present in plastic components of appliances (specifically they are usually added to flexible vinyl) according to the Prop 65 website. Electrical wiring is often coated in vinyl, and there may be other PVC parts in appliances. Black plastic that is recycled can also contain phthalates as a contamination.
2. BPA: or other bisphenols could be found in plastic (PVC or polycarbonate) components of a toaster oven.
3. Styrene: is also something I have seen a toaster oven company disclose. This could be a component of SBR rubber, some plastics when heated up, or electrical parts and cords (source).
4. Flame retardants: may be present in plastic components of appliances according to the Prop 65 website. Electrical wiring and cords also usually contain flame retardants.
5. Antimony: Tamara Rubin has found that most appliance electrical cords will test positive for Antimony (as a component of added flame retardants). When she tests electrical cords of appliances, she normally finds the level in the range of 5,000 to 15,000 parts per million (ppm). Antimony can also be found in recycled plastic.
6. Arsenic: Tamara says she often finds trace Arsenic in black plastic handles of kitchen tools and appliances. She believes it is likely a contaminant of the black pigmentation. In one test she found extremely low levels of Arsenic in the black plastic handle of a kettle (3 +/- 1 ppm). This is safe, by any standard she explains, though it’s still a Prop 65 Chemical.
7. Lead: is almost always a component of brass parts, and it can be found in plastic (both recycled and new), solder, electrical cords, nuts, painted parts, and more in appliances.
8. Nickel: is part of stainless steel.
9. Some PFAS: three PFAS were added to Prop 65: PFOA, PFOS, and PFNA. PFOS and PFOA had been mostly phased out of use in the United States by the time they were listed, but were still used in products manufactured internationally and imported for sale. PTFE (Teflon) is not on the list, but is often contaminated with PFOA (source).
10. Other Proposition 65 chemicals: may also be present in enclosed components of the appliance (such as printed circuit boards). During normal use, consumer exposure to these chemicals is expected to be negligible according to the Prop 65 website.
Is Galvanized Steel a Concern?
Zinc in electrogalvanized steel (which is likely probably used in toaster ovens, not hot dipped) doesn’t vaporize until above the temperature that toaster ovens get to.
Dr Manjunath sites this study “when zinc is heated to temperatures above 500°C in the flame during oxygen cutting or in the arc during welding, zinc oxide particles are released into the air as zinc oxide fume and can be inhaled (Mueller and Seger 1985).”
Toaster ovens don’t reach over 500°C. Most go up to 450.

Black and Decker review: I bought the one on this list a few weeks ago and the burn off is horrible. The smell is incredibly toxic, strong, and persistent, even after 5 or 10 minutes on high heat which I ran it on multiple times over a couple of weeks. At the rate it was going, I lost confidence that thing was ever going to neutralize, or if it did, it would take an insanely long time to do so and well outside the return window for a refund. Alas. The search continues…. What’s frustrating is that everything is made so poorly these days that even if there are products that are less toxic than others, there are numerous problems with them on other fronts, at least according to reviews. This problem is occurring across the board and across industries as far as I can tell.
Corinne Segura, Building Biologist
it is difficult to find one that is good quality. how do you think the off-gassing compares to other brands?
Sarah
I haven’t tried any other brands. In general, I’m super sensitive to oven-related burn offs. Whenever I’ve had to buy a new range and do the oven burn off, the idea that it will only take one or two burn offs to neutralize the smell is nowhere near what my experience has been. I usually have to burn it off countless times over many weeks, if not months, before I would dare to use it due to the persistent stench. Same goes for new dishwasher. Unfortunately… Maybe I should try the Green Pan oven. I generally like their pots and pans, though their silicon cooking utensils stink and when I used them they absolutely made the food taste very wierd, so I threw them all out. For me, the jury is still out on silicone. Maybe a bit too much hype about it being safe. Not sure.
Corinne Segura, Building Biologist
equivalent of a month of running it is normal for super sensitive folks.
Joann
Thank you for taking the time to share your research on safer product options. I really do appreciate how much work goes into gathering and posting this information. I wanted to follow up about the HYSapientia item because when I looked more closely at the materials list before purchasing, I saw that it includes a non-stick coating.
I contacted the company directly, and they confirmed the exterior is stainless steel and the interior is galvanized steel with a coating they describe as non-toxic, but they did not specify what the coating is made from. I reached out again for clarification and am waiting to hear back.
I’m finding it increasingly frustrating how difficult it is to rely on reviews or product descriptions when you’re trying to avoid chemical exposures. As someone with multiple chemical sensitivities, I really need full transparency about coatings and materials, and “non-toxic” without details doesn’t help me make a safe decision.
If anyone has found truly coating-free options (solid stainless steel, glass, or other inert materials) or companies that clearly disclose what their coatings are made of, I would be very grateful for recommendations.
Corinne Segura, Building Biologist
yeah im not clear on what that is. they used to have stainless steel baking trays when I first posted about them then they changed it. you can always buy your own baking tray though.
Joann
It’s not the baking tray it’s inside the oven that is coated, that’s my concern.
Joann Perrone
Update: Their last reply stated that there is no coating, and there was an error in their translation. However, they didn’t mention what was coated, as stated in their description.
Corinne Segura, Building Biologist
that makes more sense. i was confused. the baking tray is coated.
Elissa W
Hello, thank you for doing all this research. I wanted your input on interior walls in a toaster oven. Are anodized aluminum interior walls safe? Which is safer, this or galvanized steel?
Corinne Segura, Building Biologist
both are fine for the walls as it won’t affect the food
Patricia
Hi. Thanks for this review. Do you have any suggestions for stainless steel pan? Thanks
Corinne Segura, Building Biologist
It’s probably going to work better to buy the toaster oven first bc I could not find out the exact size of the baking pan for all of them. Other than that I would not be too worried about where you get the stainless as long as it looks and feels like stainless steel not aluminum.
Patricia
Thank you
Jane Hubbs
I’m wondering if you will be doing analysis on 2026 tabletop convection oven ? Thank you.
Corinne Segura, Building Biologist
I have updated this post multiple times since I first published it so it should be up to date. Just check with the companies and review the materials when it arrives before using it.
Esjay Gee
Hi Corinne,
First I want to thank you so much for creating this amazing website. Second, I wanted to share that GreenPan just told me the interior of their bistro air fryer is aluminum, which doesn’t seem to match with what they told other commentors on this post. I have pasted the email below for your reference.

Hello,
Thank you for contacting The Cookware Company.
Please see air fryer details below:
The interior(sides/walls) are aluminum.
The racks are stainless steel.
The sheet pan if included is aluminum coated with our nontoxic ceramic coating.
I hope you find this information helpful.
Thank you,
Belinda

Hi,
I just wanted to comment where you said ‘nickel is part of stainless steel’. There is actually less nickel in stainless steel 403, but there’s a lot of nickel in 304 which is 18/8 or 18/10.
some of Oster brands have 304 and some have 403.
Rose
I was told by a Midea representative that the accessories are coated with PTFE. Trying to get a representative to give me a straight answer about the materials of the accessories and whether they had a non stick coating took a chat message, multiple phone calls and two weeks of emails in which the representative never answered my repeated questions about a non stick coating. Finally, a rep on the phone told me that the accessories are coated with PFTE/Teflon. By email, I was told that the bake rack is nickel-chrome plated steel, the bake pan is aluminized steel, the fry basket is nickel chrome plated steel and the interior is aluminized steel.
Corinne Segura, Building Biologist
yeah that is why i reported conflicting information but once you see it it should be obvious
Aby
We had an unfortunate accident with our Emeril French door oven and as I was looking for “no -toxic” I came across your page. Your information on Emeril was short so I decided to try the Midea one. Recently heard Parchment paper is toxic? When I use my baking trays I always use parchment paper. I do believe Emeril’s cooking tray is all aluminum based on enclosed booklet. In regard to Midea, do you have links for SS trays that would fit? Thank you!
Erik
Can you please recommend a classic pop-up toaster for toasting bread (not toaster over) which is free from all of these toxins? Thanks you
Corinne Segura, Building Biologist
there is an article on normal toasters
Kristin
The link on the Buy Here button for the Midea oven needs an update. Right now it goes to Amazon’s page for Molly’s Suds Baby Laundry Detergent Powder.

Thank you for this article!
I would appreciate if you can share you insight on the 4-in-1 ChefCubii™ Combi-Steam Oven and Ourplace oven
Thank you in advance!
Corinne Segura, Building Biologist
our place oven is in the article

Thank you Connie! I see the Ourplace now.
If you’re able to I would also love your insight on Fotile Combi Steam oven.

Can I ask your thoughts on the Breville smart ovens? Was researching today and found them on some other non toxic lists so was down to green pan, Midea and breville but I don’t see them on your list and was curious why.
Corinne Segura, Building Biologist
i havent looked at Breville i dont think, what makes them more non toxic
Desiree
I did a great deal of research and was leaning towards the Wonder Oven as well and saw this and other similar articles.
Then, I decided not to replace my 30 year old toaster oven that is no longer working. I have a Thermador wall oven for bake/broil and everything else, a counter top broiler for convenience that plugs in and uses 110v, the stove, and a grill outside to use anytime other than winter. So, I asked myself, why do I really need to replace the toaster oven. What I did was research and buy a few new cookware items to replace older ones. A new Caraway non-toxic steamer and matching 3 qt pot, new Alva non-toxic non-stick sautee pan/lid and frying pans of various sizes to replace older ones that were also safe. They work on stovetop or oven. These give me some updated extra options for cooking. So, I’m done. Thanks for the info you provided on options.
Margaret
Thank you for your very thorough reply.
Margaret
Is your only objection to the Our Place Wonder Oven that the food contact surface coating on the baking tray is their ceramic coating (I’m not minimizing this, I just know I can replace and/or work around it). I’m between this and HYSapientia, but I prefer the size of the Our Place one.

Corinne Segura, Building Biologist
That is my main concern. It’s un unusual size so you would have to see if you can find a replacement tray if you want to replace it.
Desiree
My last line below, I meant to say, I’m now wary and against it, because of this. Can you comment, Thank you.
Desiree
Hello,
Your article stated that the cord for the Black & Decker contained Styrene and BPA. Otherwise, the unit itself followed good guidelines and stainless steel. I read about BPA and washing hands after handling cords. However, with the Styrene that is also in the cord, that does emit into the air. Articles state it’s important to reduce all contact with styrene to the lowest possible level, especially as it may be a human carcinogen. Having that unit in the kitchen where food is prepared is a worry. Having it anywhere would be a worry. After leaning towards purchase, I’m not wary and against it, because of this. Can you comment? Thank you.
Corinne Segura, Building Biologist
appliances are never without a pretty long list chemicals of concern. that is just how they are made. flame retardants are present and probably the most concerning (though less concerning than the types used in older appliances), many contain PFAS, BPA, plasticizers, lead, etc. All appliances that I have seen have some off-gassing at first. The styrene in the cord is not something I would worry about in particular or single out as more concerning. It may off-gas minimally.
Desiree
Thank you very much for the reply. I decided not to replace my current non-working toaster oven. I got rid of it, and I have several other cooking options that I have acquired during its lifetime, and it’s just not necessary anymore. When I stopped to think about it and what I use it for nowadays, getting another would just be either duplication or a waste of money, because of other updated cooking options. Much appreciated for your input.
Jess
If a baking pan has a nonstick coating but Farberware says “Responsibly made without PFAS, PFOA, lead, or cadmium. Product design does not involve intentionally adding to the interior nonstick coating any of these substances which may otherwise be present in the environment” –does that mean it is safe, or still bad because anything (that is not ceramic) nonstick is just bad? I noticed on the Walmart website the same product includes a Prop 65 warning for titanium dioxide, other chemicals. Just confused because I was drawn to it because it claimed to be free of the bad stuff.
Corinne Segura, Building Biologist
If no PFAS, cadmium or lead that is good, though doesn’t cover everything covers the big ones.
That does sound like ceramic though. What are they saying that it is?
Jess
It’s carbon steel with a coating. I asked Farberware if PTFE was present because it said it was PFAS, PFOA, lead, and cadmium free and this was their response: “The PTFE is a chemical that are part of the nonstick coating which is nontoxic and safe for food contact” But I found this one on Amazon that is Nonstick Carbon Steel with silicone in the coating and the listing claims to be PTFE/PFOA/PFAS/Lead/Cadmium/BPA and chemical free…too good to be true?
Corinne Segura, Building Biologist
Well they seem to be confused because PFAS is the whole class, PTFE is a PFAS.
Max
Hi, profuse thanks for the article. Did HYSapientia confirm (for #1 on this list) that 100% of the interior, linings and trays/baskets are not coated in any non-stick coatings or paints containing PFAS or PTFE. I saw on the Amazon page that there was a label that said “no PFAS”, but does that mean there is still PTFE? Do they have any certifications to prove the lack of all these chemicals?
Moreover, is there any aluminium in that model, I couldn’t find any mention of it despite it being mentioned in the article
Many thanks
Corinne Segura, Building Biologist
PTFE is a PFAS so if they say no PFAS then it means no teflon/PTFE. But I don’t see where it says that on Amazon, where do you see that?
They would have to declare PFAS on the box to sell in Colorado (that is the closest thing a certification for appliances)
“On and after January 1, 2024, a manufacturer of cookware sold in the state that contains intentionally added PFAS chemicals in the handle of the product or in any product surface that comes into contact with food, foodstuffs, or beverages is required to:
List the presence of PFAS chemicals on the product label of the cookware; and
Include a statement on the product label of the cookware that directs the consumer to a website with information about why PFAS chemicals were intentionally added to the product.
On and after January 1, 2024, a manufacturer of cookware is prohibited from making a statement that the cookware is free of PFAS chemicals unless no individual PFAS chemical is intentionally added to the cookware.”

Thank you
Just a quick addition – Does the HYSapientia have a prop 65 warning, sorry I needed to clarify since I saw many different answers in the comments. What parts would this affect?
To top up, I recently reached out to Hysapentia –> “If you are inquiring about products from the UK site, The interior of this oven is made of stainless steel and is free of non-stick coatings and toxic substances. There is no plastic inside. The Proposition 65 warning is specific to California, and testing is not mandatory, so we are FDA-certified. The steel used in our products has undergone extensive food-grade testing and complies with FDA regulations. This ensures that the materials used in the manufacturing process of our air fryers are non-toxic and safe for food preparation.”
Does the prop 65 thing apply to UK products as well?
Corinne Segura, Building Biologist
I do not believe they have a prop 65 label but that response was rather confusing. Prop 65 label is mandatory in CA if it contains the banned substances and if they are a significant risk. Though it’s not a test that they need to pass. It’s up to them to declare. And normally that label is on all boxes that go out to all of the US so that they dont need to create different boxes. Not sure if that would be on a UK shipment though.

Hi Corinne,
I recently purchased the HYSapientia 26QT Stainless Steel Air Fryer Oven With Rotisserie (1800W, 10-in-1 Countertop Oven) and reached out to the company to confirm the materials. Their reply might be helpful to you, since the trays are not stainless steel:
“Our ovens and accessories do not have a non-stick coating.
The crumb tray is galvanized, the baking tray is enameled iron, and the baking rack is chrome-plated iron.”
—Info HYSapientia (Sept 5, 2025)
In a separate email they said their air fryer basket is made of chrome-plated iron. I would love your thoughts on this, Thank you!
Corinne Segura, Building Biologist
enamelled cast iron is unusual. is that what it looks like?
Yaara
The baking tray has a black coating as shown in the picture.
Corinne Segura, Building Biologist
ok thanks, they changed that, I have contacted them to see what the enamelled iron is made of
Yaara
My pleasure. So just to verify – non of their trays are stainless steel which means, not the safest choice for trays? I’m asking because if that’s the case I’ll be looking for replacement trays.
Thank you so much for all the help!
Yaara
One more update from HYSapientia;
“The interior is made of galvanized steel.
The galvanized steel used in our products undergoes extensive food-grade testing and complies with US FDA regulations. This ensures that the materials used in the manufacturing process of our air fryers are non-toxic and safe for food preparation.”
They might have changed that as well since you last reviewed it.
Thanks again for all your hard work.
Corinne Segura, Building Biologist
im trying to confirm some things with them but they are not replying to me. what email address are they replying to you from?
Yaara

Corinne Segura, Building Biologist
thanks oddly they are not replying to me at that email address
Karen Hudson
We ordered the Black and Decker 8 slice Toaster Oven in stainless steel inside and out. When it arrives. the top, back. and sides were black. Is the black coating safe? We wanted an all silver stainless steel toaster oven. Thinking of returning it for a replacement.
Karen
Corinne Segura, Building Biologist
Hi, I’m not sure I havent looked at that black coating, depends on what it is
Mary Skiba
Just put a little bowl with about an inch of vinegar in my toaster oven I have MCS for 22 years. This is how I have battled with BOC’s and appliances and other things.
Even if I get a new vacuum cleaner or a shampooer, I put a pan of vinegar. I put an oven on top of it. I stand the shampoo on top of it or whatever I have even the sewing machine I cover the whole thing with plastic bag tucked the plastic bag under and I’ll leave it for two or three days it works for me and it is the only way I have found to fight these VOCs vinegar and I use steam as well with other things my MCS is severe
Elaine
I have a Breville BOV845 smart oven and a Ninja pressure cooker OL500. Can you tell me if there are any PFAS or PFOS with this product as i had bought them before i knew anything about these contaminants? Thank you
Corinne Segura, Building Biologist
You’ll have to see if they have a public statement about PFAS and then ask them about individual parts. You can also tell by looking at them most of the time, if they have non-stick parts or fingerprint resistant stainless steel.
AnnaMarie White
I had a couple of breville ovens. They advertised at the time, that their oven was non-toxic. None of the harmful plastic coatings found in teflon. I used these ovens for many years and every day every month and year over year that thing dug my grave deeper and deeper. I was in the verge of a heart attack and circling the drain. Then one day, the oven door broke. I unplugged it. Suddenly my sense of taste began to return. I thank God that oven door broke
And saved my life. Thank you Universe.
Yumi Powers
I just purchased Panasonic FlashXpress 1300W-NB-G200P toaster oven countertop which is described as “designed with PFAS-free materials for safer cooking”. I bought it as it fits my needs with small size but I can’t seem to find any other info regarding the inside matierials or the tray that it comes with. Have you reviewed this Panasonic toaster? Please share any info you may have regarding this unit. Thank you!
Corinne Segura, Building Biologist
They only say the interior is PFAS free and panasonic in general says their products are PFAS free on food contact surfaces and handles. if the exterior stainless has a fingerprint resistant surface that could still be PFAS.
C
I appreciate you SO MUCH for doing the hard work to research all of these products!
I have a pet bird so need to avoid PTFE, PFAS, etc and trying to get an accurate, non-canned response from these companies has been impossible. I’m purchasing the Black and Decker model you recommended but in the 6-slice size.
In the chemical disclosure they sent, it said model TO1950SBD contains BPA and Styrene in case any of your readers wish to avoid those. Thank you 🙂
Corinne Segura, Building Biologist
thank you, im glad you found a bird safe option! yes i have BPA and styrene listed for black and decker, they say it’s in the cord though so not too bad.
Karie Butler
How is Aluminized (plain) steel as the interior material?
I asked the company about Oster® Manual French Door Air Fry Oven model TSSTTVFDMAF:
Interior: Aluminized (plain) steel, no non-stick
Exterior: Stainless/charcoal-coated steel
Racks & trays: Steel (chrome-plated for racks), baking pan steel
PFAS & non-stick: None present in interior or included accessories
Corinne Segura, Building Biologist
it’s fine as the interior walls
Karie
Thank you! This article was very helpful
Harriet
Hi
Great research and info. I’m looking for a small toaster oven without an air fryer.
I don’t like the look of the black and Decker. Any other small ones? Used to have a Breville before I knew about non stick but the small oven was the right size.
Thank you
HB
Corinne Segura, Building Biologist
there is another small one on the list. also the same brands usually make different models of toaster ovens. which usually are made of the same materials.
Karie
Since there are no Ninja Foodie ovens in this list I assume they have not good materials?
Corinne Segura, Building Biologist
not necessarily, I only reviewed the brands in the article
Miranda
Thank you so much for your research on this topic. I went down a rabbithole of trying to find a non-tox air-fryer and was at my wits end before finding your website. You truly have helped me and I am so grateful!
I decided to go with the Midea Convection Oven (option #2) on your list. Do you have any good recommendations for where to find replacement baking trays for smaller appliances like this? I can’t seem to find good ones or the Amazon link is at a “currently unavailable” status.
Thank you again for your research and help!
Corinne Segura, Building Biologist
I’m not sure exactly, i have searched but also i couldnt get the exact tray sizes for all of them without seeing it so I couldnt do a really accurate search
Miranda
Okay, thank you for responding! I thought I would check. If I end up finding anything, I will pass it along.
Anita James
Hi Corrine,
Thank you for your in depth research on non toxic toaster ovens and air fryers. Your article is a treasure and in certain cases a life saver as well. I have ordered the Black and Decker Extra Wide 8-slice toaster oven that turned out to be too big for my counter. I clicked the link you provided with the other Black and Decker products and thinking on getting the one bellow. Is it still your top pick and a safe toaster over? I am hoping the only difference the size not the quality and materials. Thank you for your answer in advance.
PBLACK+DECKER 4-Slice Toaster Oven, Even Toast, 4 Cooking Functions Bake, Broil, Toast and Keep Warm,…
Corinne Segura, Building Biologist
It’s likely that the four slice has the same materials but you would have to ask them or see it in person to know for sure.
Helene
I have a cuisinart toaster oven. The inside walls are nonstick. As long as no food touches the inside walls, is it safe to use?
Corinne Segura, Building Biologist
the article goes over potential risks of PFAS coatings in toaster ovens
Elyse
Thanks for the article. A couple of FYI’s based on my experience:
There are models of the Cuisinart countertop convection/toaster ovens that do not have non-stick interiors. I have one that is most likely anodized aluminum or anodized steel.
However, it being impossible to clean anything greasy that bakes onto it, I am finally retiring it after 5 years of otherwise perfect service. They’ve become so expensive, though, I am switching to the Black & Decker as I want to have at the width for at least a 12″ pizza, or, ideally a 9×13 pan.
The Emeril oven looks great but it isn’t wide enough for me. But fyi it has an anodized aluminum or other anodized metal interior. Doesn’t look like non-stick to me.
Thanks for all your research. I’m keeping an eye on Amazon for your top pick. Previously much less expensive than @ Walmart.
On the Amazon comments for your top pick, one person wrote that the interior was not actually stainless steel but instead was anodized aluminum. I doubt that’s true but everyone else said it was easy to clean!.
Corinne Segura, Building Biologist
thanks for sharing

What about wonder oven?
Corinne Segura, Building Biologist
i review wonder oven in the article
DKI
Wow, I didn’t know PFAS was also in toasters, microwaves, etc. Thanks for this list! Saved me hours of research 🙂
P.S. Sorry I know this is for toasters, but I just found a Panasonic microwave where they state there is no PFAS in their chemical disclosures, if anyone is looking for a microwave without PFAS. It has prop 65 chemicals according to the disclosure, but I think all microwaves do. Details below
Panasonic – 1.2 Cu. Ft. 1200-Watt Countertop Microwave Oven with Inverter Technology – Stainless Steel
Model:
NN-SN66QS
Chemical Disclosures
“This product contains no PFAS but chemicals listed on the California Department of Toxic Substances Control’s Candidate Chemical list. For more information, please visit https://na.panasonic.com/us/PFAS-information.”

I am looking for an electric wall oven that does not let off the noxious fumes when turning on the oven for the first and second and third time… I have severe breathing issues and am searching for an oven that does not have these awful chemicals…. I do open all windows and fans but the smell is awful and I can’t even be in my home.
Please let me know of any electric wall ovens that might not have the chemicals….
Corinne Segura, Building Biologist
all ovens smell at first. see the article on non toxic appliances
Christina Tomko
What are your thoughts on the Breville Smart Convection Toaster Oven Air?
I received this for Christmas and I can return at Williams Sonoma but the options of a toaster oven through that store is limited. Looking for one with all the features BUT also chemical free. Would love to keep it but I am traumatized by the PFAS in nonstick especially since I have suffered from infertility. Thank you for your help!
Corinne Segura, Building Biologist
with almost all brands and models I would personally replace the baking tray with a stainless steel options. so if you can do that, and if the interior lining of the whole oven is not PFAS (which it usually isn’t) then I would just go with that
Kuzucuk
Would you say the wonder oven is safe if you chose not to use the ceramic tray?
Corinne Segura, Building Biologist
yes I think the tray is the only part that has the nano particle potential concern
Joshua E
everything ab the wonder over does it apply to the wonder oven pro.
also the material on the outside what is that made out of bc i know they have a stainless steal option. Just curios if the others are a safe option (colored exterior)
Rachel Sue Ritz
I’m looking for a toaster oven where the inside walls are easy to clean. I’ve had 2 cuisinarts and they are very difficult to clean.
Corinne Segura, Building Biologist
if it’s non-toxic by my specifications most of them won’t have any non-stick coating on the interior walls that makes it easy to clean. the greenpan one does have the non PFAS non-stick coating on the inteior walls I believe though do double check
Rachel
If I understand you correctly all except the Greenpan will be difficult to clean unless it has a nonstick coating. Unfortunately the Greenpan leaves only 1 in clearance under my kitchen cabinets.
Monica
Thank you for sharing all your research! So grateful to you.
I bought a Cuisinart CTOA-130PC3 from Costco last year. Do you have any information on that one?
Corinne Segura, Building Biologist
it sounds like i need to add cuisinart to the article. will have to research them first
Monica
I emailed Cuisinart. They sent me to this chemical disclosure page. I can’t make sense of it. Maybe you can. cuisinart.com/chemical-disclosure
Corinne Segura, Building Biologist
well it has PFAS, where are they on the one you have, the baking tray only or the walls as well?
Monica
When I enter the model number (CTOA-130PC3), it lists a bunch of chemicals in a chart, but it doesn’t specify the location of each.
Monica
My husband says the trays are stainless, so it must be the walls.
Claire
This oven TOB-260N1NAS has been discontinued in the nonstick version and replaced with fully stainless. When I called they confirmed no nonstick surfaces. They couldn’t tell me, however, what the enameled baking tray is made of and when I asked about the pizza stone and oven racks, they directed me to the chemical disclosures, but I think it hasn’t been posted there. I’ve emailed them to ask for more information.
Claire
Please scratch my response. They don’t advertise that it has nonstick surfaces like they did for the last version (and the agent on the phone told me it doesn’t have them), but then both via email and another phone call they said it does have nonstick surfaces and the same disclosures as the prior model. Sigh.
Emilie McVey
I purchased the Oster toaster oven wi the air fryer function. Two things: the user manual said the tray has a nonstick coating, so someone misinformed you. And the air fryer function does not make foods crispy; I wound up sending it back to Amazon.
Corinne Segura, Building Biologist
It’s def possible that the Oster reps were wrong but they manuels are often outdated esp right now as they transition away from PFAS. But either way I noted that I recommend the trays be replaced. I will make a note about the air fryer part.
Jessica K
Unfortunately the Oster Digital Air Fryer Oven or Black and Decker models recommended are slightly too big for our space available. Would the Black and Decker TO3215SS model have similar internal components and safety?
Corinne Segura, Building Biologist
yes likely but you’d have to ask them
Jessica K
Can I ask who I call at Black and Decker or any company that would know the answer to the questions? On that same topic, can I ask what are the most important questions to ask? Thank you for all your help and highlighting these important issues.

Hope
Hello Corinne! I am hoping you can provide some guidance on selecting between the Green Pan Elite Convection Air Fry Oven and the HYSapientia. Per my communication with Green Pan in January of this year the following materials listed below are used in this version of the Elite countertop oven. My biggest concern was the use of galvanized steel on the interior and it releasing toxic fumes into the air. The information online is confusing around this topic and after reading about the concerns of galvanized steel on Tamara Rubin’s website, I was thinking this countertop oven would be a no go at this point. However, after reviewing the information below, you mentioned it would not be of concern. I am also less concerned with what accessories these come with as I’d use all stainless pans anyhow. My family and I are in need of some sort of countertop oven quickly as our leased home has a gas oven and it’s unbearable to cook something in there. Any and all guidance would be much appreciated. Thank you again!
FROM GREEN PAN REP:
The interior of the Elite oven is galvanized steel.
The oven racks and broiler rack is stainless steel.
The crumb tray, basket , baking, and pizza accessories are ceramic coated over aluminum.
No need for any chemicals like PTFE, PFOA or any other type of PFAS and we do not add any Cadmium or Lead. GreenPan cookware is also BPA free.
Our Thermolon coating does not contain any Nano particles. Accordingly, there is no possibility for Nano particles to leach into the food when cooking with GreenPan.
Corinne Segura, Building Biologist
I talk about Green Pan in the article and just added a section on galvanized steel.
Hope
An update: I reached out to GreenPan and they would not disclose how they galvanize their steel. To me that seems concerning but maybe I’m overthinking it.
Corinne Segura, Building Biologist
it doesn’t matter how they galvanise it.
Hope
Ah okay, got it! Thought it needed to be electrogalvanized and not hot dipped. Thank you for your guidance. This provides great relief to us. Much appreciated!!!
Myra Pumphrey
I just bought an aria digital air fryer/toaster oven because it is all stainless steel and claims n forever chemicals. Instructions tell me to turn the oven on for 15 mi. To ‘burn off protective coating’. Do you know anything about these coatings and do you think this product is safe?
Corinne Segura, Building Biologist
this is likely to burn off a thin layer of manufacturing residue, oils, or coatings that are applied during the production process. you can also wipe it down first with dishsoap everywhere that can get wet. if you have MCS you could run it outside the first time you run it.
Christine A
I just purchased a Breville mini smart oven model BOV450XL and it has the warning which started me on this journey of research. We had PFAS in our water and it caused so many thyroid, liver and endocrine problems for me and now I’m panicking that I just brought a PFAS toaster into the house. I didn’t see it on your list so I was wondering how dangerous it really is to use if I upgrade the baking pan to a ceramic one?
Corinne Segura, Building Biologist
you can change out the non stick pan if that is the only part that is PFAS on the interior
Justine
Beyond grateful for this information! Thank you for all the tremendous research you did and for sharing it!!!
Corinne Segura, Building Biologist
thank you
Rachel
Hi Corinne,
I so appreciate your research and the fact that you share your findings! It is hard to find a non-toxic air fryer/toaster oven. I found that your top choice is out of stock on Amazon and Walmart’s websites. I did find it here which I think is the manufacturer’s website and wanted to verify that this is the same product:
https://hysa.store/collections/air-fryer-oven/products/hysapientia-air-fryer-oven-26qt-10-in-1-with-rotisserie
Thanks!

Do you know if the Emeril air fryer toaster oven has any nonstick coting on the inside?
Corinne Segura, Building Biologist
the brand is mentioned in the article
OK1.16.25
Great info, does this Black & Decker model seem similar to #3 you listed in the article, the 8-slice toaster oven? For instance, the only BPA and styrene B&D says is in the cord itself? Thanks so much. Product sample: https://www.blackanddeckerappliances.com/products/cooking-appliances/convection-and-toaster-ovens/to3217ssrfp-crisp-n-bake-air-fry-6-slice-toaster-oven.aspx
Corinne Segura, Building Biologist
Yes I would expect it to be made of the same materials but you would have to ask them to be sure. There can be more Prop 65 chemicals than the two that they disclose. They don’t have to list out all of them.
Halley
Do you have any recommendations for “safer” microwaves? I looked through your website, but didn’t see much on that?
Thanks for all you do!
Corinne Segura, Building Biologist
article on microwaves is coming soon
Halley
Thanks for getting back to me. I’m just looking for a “safer” microwave options. Is there anything else to be concerned about when looking for a microwave other than black plastic?
Thanks!
Robin
I recently read that your number one pick here, HYSapientia, has aluminum in it. And when that heats up it will probably out-gas aluminum fumes, which are highly toxic to the body. You might want to do a bit more research to look into this. I was going to buy it until I read that. Unfortunately, I have researched so many ovens I cannot find the page that mentions aluminum. But I would be careful and check it out. Also, many of the trays in the supposed non-toxic ovens are aluminum or have a non-stick coating. Thank you fr all you are doing to educate and help us create healthy homes. I so appreciate it. 🙂
Corinne Segura, Building Biologist
aluminum does not offgas at toaster oven temps. Only a concern when touching liquid or acidic food
Robin
I am considering the #1 over you suggested. But just read this. Can you shed any light on it. Feeling discouraged, and wondering if there are any real non-toxic toaster ovens out there. Sigh…..

According to information available, while the Hysapientia stainless steel air fryer oven may claim to be PFAS, PFOA, and PTFE free, it does still carry a Prop 65 warning which indicates the presence of chemicals that could potentially be harmful, including PFAS, which is likely due to the non-stick coating on the internal components, despite claims otherwise; some users have reported disappointment regarding this discrepancy between advertised features and the Prop 65 warning on the product.
Key points to consider:
Prop 65 warning:
The presence of a Prop 65 warning on the product suggests that it may contain chemicals considered harmful by California law, potentially including PFAS.
Customer reports:
Some users have reported that their Hysapientia air fryer came with a Prop 65 warning despite claims of being PFAS free.
Lack of transparency:
There might not be complete transparency regarding the exact materials used in the non-stick coating, leading to confusion about its safety.
Corinne Segura, Building Biologist
that is googles AI overview which are not accurate. There is no prop 65 warning where they are sold and I asked them directly if there is a prop 65 warning and they said there isn’t
Robin
Thank you SO much. Your reply is very helpful. I appreciate your time and patience. And, good to know about the AI. 🙂

Thank you for sharing your articles. I was able to order online HYSapientia at Walmart.
Thank you everyone for contributing the chats, I am learning a lot. God bless you.
Corinne Segura, Building Biologist
oh! thanks!
Matt
Just an FYI I spoke with a rep with Midea. Your top choice is inaccurate unfortunately and negates everything after that. It has a prop 65 warning… you left no details on this one but I contacted them directly and they said:
“For this specific unit, the warning could be due to the presence of chemicals in the materials used for the oven’s construction, such as certain plastics or coatings. It’s a common precautionary measure to inform consumers, especially in California, about potential exposures.”
AKA it has PFAS. Even the rep agreed with me. Therefore everything you wrote after that was null and void. I still have not found a true PFAS free unit.
Corinne Segura, Building Biologist
It says in the post that it has a prop 65 warning. But the warning is not for PFAS according to the reps, they said it has no non stick coatings.
Corinne Segura, Building Biologist
also based on a video of all the components it doesn’t look like there are any non-stick coatings
naa0824
Hi! If it has galvanized steel on the interior of the toaster oven is that toxic? I’ve heard conflicting info about zinc galvanized steel being toxic in toaster ovens.
naa0824
This is the one in particular I’m talking about.
https://valcucina.com/collections/val-cucine-air-fryer/products/val-cucine-10-in-1-smart-air-fryer
Corinne Segura, Building Biologist
it’s not
Eric
In the user manual that comes with this product on page 11, it says “”Do not use abrasive cleansers, scrubbing brushes and chemical cleaner as these will cause damage to the non-stick coating of baking tray.”
Eric
Also, on the box it shipped in there is a prop 65 warning and a link to their site: Diboron trioxide, Iron, Nickel, and Nickel Compounds, Chromium Compounds. For more info about chemicals in this product including PFAS chemicals, visit midea.com/us/disclosure-on-ab-1200
Corinne Segura, Building Biologist
interesting, their disclosure for the baking tray at that link you sent discloses: Diboron trioxide, Nickel monoxide, Iron, Aluminum, Copper, Manganese and manganese compounds. Does the baking tray look and feel like it’s not pure metal but has a coating on it? I’ll add something to the post but it’s not clear if it has PFAS (it can be nonstick without PFAS). New laws for 2025 don’t allow PFAS in cookware in Minnesota and in Maine it must be declared.
Eric
I would say I expected the tray to be heavier.
Justine
Hi there! It looks like the Oster ten function toaster oven DOES have a CA prop 65 warning (based on an Oster customer service response on the product’s webpage). Could you please clarify?
Corinne Segura, Building Biologist
If that is true they are out of compliance with Prop 65 laws that require that be listed on any page that is selling it for people to see before purchase.
Annette
I am interested in buying #4 on your list, but I noticed that if I click on the the first link that says “Oster 10 function air fryer oven, toaster oven”, it brings me to one item on amazon. If I click on the link at the bottom that says “Buy here” it brings me to a completely different item on amazon. I am wondering if you can tell me which of the two items is actually recommended as #4 on the list. Thank you!
Also, I am wondering if you have reviewed the Emeril Lagasse Power AirFryer 360 Model S-AFO-001? I received this one for Christmas and love it, but began researching when I noticed that it has a “prop 65” warning label on it.
Corinne Segura, Building Biologist
both of them have the same material makeup but i fixed that link bc one was not available. I talk about Emeril Lagasse in the article
Sienna
First and foremost, thank you so much for your insightful article and all the incredible work you do! What you’re doing is truly meaningful, and I deeply appreciate it!
What do you think of Midea Flexify French Door Air Fryer Oven? I emailed them about the materials and this is what they reply:
Interior Lining or Coating: The oven does not include any non-stick coating, which is a positive aspect as it avoids the use of potentially harmful non-stick chemicals.
Cooking Tray and Basket Material: The cooking tray and basket are made of stainless steel. Stainless steel is generally considered safe for cooking as it does not leach harmful chemicals into food.
Other Materials: The oven’s construction primarily uses stainless steel and other standard materials for kitchen appliances. However, the presence of a California Proposition 65 warning indicates that the product may contain chemicals known to the state of California to cause cancer, birth defects, or other reproductive harm. This warning is common for many products and does not necessarily mean the product is unsafe, but it is important to be aware of.
Corinne Segura, Building Biologist
This sounds good I will add them to the post! and dont forget to remind them that prop 65 as of 2025 now requires they say at least one of the chemicals they are positive for.
Julie
Hi,
I clicked on the Hysapientia Air Fryer Convection Oven, and it says thus in the description:
‘aluminized diamond-shaped inner liner’
Corinne Segura, Building Biologist
yes i say that in the article
Derick Melgar
So would you recommend any black and decker toaster oven as long as we don’t use the banking pan ? other than that everything else is safe ? I recently bought one however I saw the cancer warning so I’m thinking about taking it back
Corinne Segura, Building Biologist
It’s likely they all use the same basic materials but I don’t know that for sure
Lynn Peterson
Hello Corrine,
First of all thank you for all of this research and hard work. Much to my my families’ dismay I had put off getting a toaster oven/air fryer due to the overwhelm I felt when trying to find a non-toxic model. Since I could not find the Hysapientia model and I read your article prior to you adding the Midea model, I ended up doing more research using your guidelines. I ended up purchasing a NuWave Bravo XL Pro. They have two versions of this model, one is marked PSAF free because it contains accessories that are supposedly all PSAF free. The griddle/grill that they include has a ceramic coating. The interior of unit is and crumb tray are aluminized coated steel.
Have you researched this brand before? I feel pretty sure it is safe but now I am second guessing myself. I would love to hear your thoughts. Thank you…
Corinne Segura, Building Biologist
not clear what the baking pan is made of exactly
karen h
I want to thank you for doing the research and sharing your findings with us. I appreciate.
Jared
Hi Corinne,
Thank you for your research, this article is incredibly helpful. Do you know about the safety of the Nuwave Bravo Toaster Oven (or Nuwave in general)? I attached a link to my name of one I was looking at that says the inside and outside are stainless steel, PFAS free, and the accessories are PFAS free. Thank you for your help!
Corinne Segura, Building Biologist
PFAS free is good, you might also want to know about aluminum esp if the pans are aluminum, you have to ask the questions I asked in the article
Jennifer
Hi,
Thanks so much for all your great information. I bought a Toshiba ChefFry Toaster Oven/Air fryer. It came with the Prop 65 warning on the box–which was not on the Amazon website. The warning was for diboron trioxide, nickel and nickel compounds, chromium compounds, and PFAS. I called Toshiba and they said all those chemicals were only used on the outside of the machine, but they said there was a nonstick coating on the inside (which was not Teflon) that would burn off. I see you said that there would always be Prop 65 chemicals inside a toaster oven. I’m trying to use a toaster oven more because my rental apartment has a gas stove, and I thought this would be a good appliance to add to the mix, but it seems there is no avoiding one problem or another. As someone with chronic health issues, it is all very disheartening.
Corinne Segura, Building Biologist
PFAS are in the non stick coatings which are inside, they do not burn off. I would prefer to avoid PFAS
Marie
Hi,
Thank you so much for this amazing information and insight!! I did want to get your further perspective on the The BLACK+DECKER Extra Wide Convection Toaster Oven. I just called to confirm the specs, and they did confirm the outer is stainless steel and the inner is stainless steel with zinc coating. However, they did say that there are some interior, electrical component parts that you can not access (such as the timer) that are not BPA free. I did not understand fully, and was hoping you could provide more context on this and the overall safety / risk concern.
Thank you so much!
Corinne Segura, Building Biologist
see the list of prop 65 chemicals and where they are found, there will always be prop 65 chemicals in interior components
Emily Moretti
Thank you for this information. It is super informative.
I was searching for a more compact toaster oven for my mom.
Following your tips and information I found the Hamilton Beach 31193C Digital Display Countertop.
I was concerned if interior was stainless steel.
Any information regarding the safety and quality of this one would be helpful.
Thank you again for all this.
Emily
Corinne Segura, Building Biologist
its likely all Hamilton Beach toaster ovens have the same materials as the one i mention in the article but you can ask them if it looks different
Genesis
Any thoughts on the SKYSHALO 7-IN-1 Air Fryer Toaster Oven 18L Stainless Steel 1700W Convection Oven? Trying to make my Christmas list and saw that on the market…
Corinne Segura, Building Biologist
what are the materials
Genesis
Galvanized plate liner for the inside (non stick for easy cleaning it also says) and the outside material stainless steel. The same goes for the trays it comes with (galvanized).
Corinne Segura, Building Biologist
ive never seen galvanised trays, that doesnt sound right. galvanised interior walls is the norm, sometimes they call that non stick
Genesis
Okay than you that’s good then, I just wanted to know if for the interior that material was good because I’m pretty I can replace the trays etc. I copy paste what the description says here: This toaster ovens countertop comes with an electroplated baking rack, an aluminum baking tray, a galvanized sheet crumb tray, an electroplated frying basket, a pair of heat-resistant gloves which makes it easy to handle hot food, and a user manual. The whole rich accessories enable you to bake all kinds of foods with ease.
Corinne Segura, Building Biologist
ah yes the crumb tray is often galvanised, but that is not what food touches. the baking tray is aluminum. whether they are referring to the galvanized interior sides as non stick is not know for certain, it could be but it could also be PFAS
Jared
Hi Corinne,
Thank you for your research, this article is incredibly helpful. Do you know about the safety of the Nuwave Bravo Toaster Oven (or Nuwave in general)? I attached a link of one I was looking at that says the inside and outside are stainless steel, PFAS free, and the accessories are PFAS free. Thank you for your help!
L
Did you ever get an answer about the nuwave oven?! I’m looking at the same one, thanks.. L
Toni
Re: #4 on your list of preferred toaster ovens. It’s a Hamilton Beach and you note that the interior is galvanized steel and then you also say that H.Beach makes another toaster oven and you have a link to that one. I prefer the one on the link; however, I don’t understand whether or not you are saying that the interior of this smaller one is made of steel as well.
Please let me know.
Corinne Segura, Building Biologist
i believe they are made of the same materials
Helen P
Do you have any information on the cuisinart CTOA-122?
Corinne Segura, Building Biologist
“This product contains Polytetrafluoroethylene (Teflon), Fluorinated Ethylene and Propylene, Perfluoroalkoxy alkane Polymer, Manganese and manganese compounds, Iron, Nickel and Nickel Compounds, Phosphorus, Chromium Compounds, Chromium Total, Aluminum.”
Helen P
Wow I didn’t realize how many different materials are used. If I do not use my oven above 450* will I be safe?
Glenn I.
Hi Corinne. Thank you so much for this article! This is the most thorough one I’ve come across. What about the Cuisinart TOA-70? Thanks!
Corinne Segura, Building Biologist
does it have that same warning?
Glenn I.
Sorry, I accidently commented under someone else’s post. I was just researching this one product I got as a gift and it made me appreciate your hard work even more. I couldn’t find anything. This product was already available in 2021. Your article was published in 2023. I’m guessing you’ve already spoken with Cusinart and none are recommended. Thanks!
Genesis Matias
Hi I currently saw the Cuisinart air fryer toaster oven on sale so I was wondering if it’s a good option? On their website says the exterior is stainless steel and the interior material is metal. Is that a good thing? Also the Bella air fryer toaster oven mentions that the interior is a non toxic material and pfas, would that also be a good option?
Corinne Segura, Building Biologist
most of them have metal walls, but if the walls are non stick it could be PFAS. they you can look at the tray to see if it’s non stick.
Genesis Matias
So stay away from any that says metal walls? Even if it says PFAS FREE
Corinne Segura, Building Biologist
Metal walls are fine
Riya
Hi
Thank you so much for all the hard work you are doing for us. Is there any replacement of HYSapientia as it’s not available anywhere
Corinne Segura, Building Biologist
not with the exact same specs that i know of
Michelle Wallach
Wonder oven is being advertised quite a bit on reels has ceramic coating. The HYSapientia is unavailable on Amazon. Thank you.
Corinne Segura, Building Biologist
i talk about wonder oven, it’s not one i would use
Maria Norton
Which one do you have?
Corinne Segura, Building Biologist
i don’t own a toaster oven, but i’d buy any of the ones on the list and if they have an aluminum pan I would not cook on that myself.
Obra
Thanks for this round-up. Did you evaluate the Panasonic Flashxpress toaster oven? That one is recommended by both the New York Times and Emily Oster, so I’d love to know whether you found any concerns!
Corinne Segura, Building Biologist
interior looks galvanised, rack is the common chrome over steel, baking pan is the common enamel which likley has PFAS
Obra
Thank you!
MJ
I can’t find more detailed information on my toaster oven/air fryer. I have the Kitchen in the box 32 QT Extra Large Toaster Oven Air Fryer Combo, 18-in-1 Convection Toaster Oven Countertop with Baking, Dehydrate and Rotisserie, 6 Accessories, 1800W
Do you know if they use teflon in this? So thankful for your posts!!
Corinne Segura, Building Biologist
the walls are metal, the baking pan is the only part that is not clear. you may want to replace the pan with a stainless steel option if you have any doubts about it
Mary Anne Burgan
I’m looking for a counter top double oven with as many functions as possible. I heard convection ovens are good.
I bought an Emeril Lagasse 360 plus but I don’t if it’s good and actually would like the double oven since it’s only me and I’d be able to cook items separately.
I greatly appreciate all the research you’ve done and for your suggestions for me, in advance.
Thank you
Corinne Segura, Building Biologist
I mention that brand in the post

What is your opinion of this air fryer?
https://www.amazon.com/dp/B08SWMFSB6?ref_=cm_sw_r_cso_cp_apin_dp_JNZ4ZFAX5DC3RPFH25GZ&starsLeft=1
Do you know of a stainless steel bake pan or crumb tray for it? Thank you very much for the blog.
Corinne Segura, Building Biologist
You’d have to search for a stainless steel baking pan with those exact dimensions
Bruce Herman
You should also be aware that galvanized stainless steel is not OK for toaster ovens. ” For hot-dipped galvanized steel the recommended maximum temperature is 392 F (200 C), before the metal presents a toxicity risk.”. Aluminized stainless is good to about 1000 F if unscratched.
Corinne Segura, Building Biologist
That is not a reliable source, that quote. Scientific sources say that zinc in electrogalvanized steel (which is what is probably used in toaster ovens, not hot dipped) doesn’t vaporise until much higher temperatures. But I will have the toxicologist look it over.
Bruce Herman
Thanks, intertesting.
I also have an inquiry into Emiril LeGass about the 26 QT Extra Large Air Fryer, Convection Toaster Oven with French Doors. They claim no non-stick and stainless steel interior, but theie chemical disclosure page also shows PTFE, Styrene, BPA, and carbon black. I suspect the PTFE is on the baking pan, the Styrene part of ABS feet and the carbon black and BPA due to the power cord – we shall see. I will let you know what I find out. (I find your postings ttypically he most infotmative.)
Corinne Segura, Building Biologist
ok thanks
Shawnie
have you found out anymore information on this?
Corinne Segura, Building Biologist
Dr Manjunath sites this study “Burning of zinc yields zinc oxide. When zinc is heated to temperatures above 500°C in the flame during oxygen cutting or in the arc during welding, zinc oxide particles are released into the air as zinc oxide fume and can be inhaled (Mueller and Seger 1985).”
Bruce Herman
Hi,
Your top pick is described on Amazon as being aluminized, not galvanized.
Corinne Segura, Building Biologist
thank you
Gerri
Is aluminized risky? Thanks for all the valuable info.
Corinne Segura, Building Biologist
not as the interior sides, only as food contact areas
Gerri
Thank you. Does the exterior matter regarding chemical release when hot?
Corinne Segura, Building Biologist
it would be a god idea to avoid plastics with bisphenols or recycled e waste plastic on the exterior regardless of temperature. however I don’t think polycarbonate which has bisphenols is what the plastic knobs are made of
Janine
I was very interested in the Wonder Oven prior to reading your article (which was magnificently helpful and I thank you for writing it!). I really wanted it based on function and size. I actually ordered the Green Pan oven but it was way to big for my tiny space. So, I contacted Our Place, the manufacturer of the Wonder Oven and copied and pasted your comment regarding this oven.
This is the response I received:
“Hi Janine,
Francis here from Our Place. Thank you for reaching out!
I understand how the mention of nano-materials can raise questions, so let me help clarify.
The use of nano-materials in this way is common in modern nonstick coatings, and these coatings are rigorously tested for safety, including their non-leaching properties. Still, I understand your concern and want to assure you that these coatings are designed to be food-safe when properly maintained.
It’s important to emphasize that the safety of this ceramic coating depends on the integrity of the surface. As long as the coating is undamaged and properly cared for (avoiding metal utensils or abrasive scrubbing that might scratch the surface), there is no risk of particles being released during cooking.
Again, we understand your concern but as long as the bake tray does not have deep scratches that would show the core, there is nothing to worry about. I also want to note that we offer 100 days for returns for refunds, if ever you change your mind, please let us know so we can provide the return instructions.”
It’s not a perfect answer but I did end up ordering it anyway. I need something multifunctional that is small and I will diligently keep track of the condition of the pans.
Just wanted to share this. Thanks again for your handy work!
Jessie Goldfarb
Greetings and thank you so much for this great info and service. Am I correct that the Hamilton Beach Toaster Oven is as non-toxic as their Air Fryer Toaster Oven? And if you know, why get the Air Fryer Toaster Oven instead of the plain old Toaster Oven? I’m not looking to fry anything, if that helps. Thank you again!
Corinne Segura, Building Biologist
likely is made with the same materials as the one i listed but you will have to check
Jessie Goldfarb
Thank you so much!
Kelly Kriklava
Hi! Do you have any thoughts on the GE air fryer/oven 8 modes?
https://www.amazon.com/dp/B08SWMFSB6?th=1
Corinne Segura, Building Biologist
whats the baking tray made of?
Kelly Kriklava
The tray is aluminum and the wire has lead. Maybe if I just replace those?
Corinne Segura, Building Biologist
you can replace the tray, not sure what you mean by the wire.

Hello. Any breville oven you recommend ?
Corinne Segura, Building Biologist
looks like in inside of breville ovens have a nonstick coating, though i’m not 100% sure
shelby
Hi I have a breville smart oven. if I use my own stainless steel pans is that okay? im confused because what is the non stick for if the food is going on a pan. like why do they need that inside of the oven? is the wonder oven safer if I just use my own pans too?
Corinne Segura, Building Biologist
non stick on the interior sides just makes it easier to clean
Sean K
First of all, thank you very much for your work right here. I’ve been looking for non stock coating in air fry and mini oven but sometime they don’t really say until i found out when I bought it. Your work really help me to understand more about these chemicals. I love your list of products however it’s too big for my kitchen counter top. I found this one and can not find detail about it : BLACK+DECKER 4-Slice Crisp ‘N Bake Air Fry Toaster Oven, TO1787SS, 5 Cooking Functions, 30 Minute Timer, Stainless Steel. Would you be able to know this is safe without non stick coating and no prop 65 or any chemicals that I should concern. I’m sorry to ask but I really could not find the info. Thank you.
Corinne Segura, Building Biologist
you’d have to ask them for the details that you want to know, but it’s likely the same as the other black and decker options
Renee
Hi,
I just purchased the “HYSapientia 25 Quart 10-In-1 Air Fryer Oven (Double Layer Glass Door) With Rotisserie” from Newegg. After I unboxed and started cleaning interior I saw that the interior light inside has a large plastic piece attached to it. I cant remove it and now am concerned. Have you heard anything about this plastic component? I am bummed as I cant return it now. Thanks!
Renee
So sorry! Disregard this comment, I just found another review elsewhere that says the piece is actually glass and it is removable. Ooops.
Chris
Thank you so much for your work. Would you comment on potential lead contamination that could be in a zinc coated surface such as the interior of the toaster ovens? There seems to be some debate online about this, but I would like to refer to actual research. My thoughts are (1) how likely would it even be that there is lead in the zinc coating and (2) if there is lead in the zinc coating, could it potentially vaporize? I read that lead could vaporize when heated to 750 degrees F, which would be above the threshold of the toaster oven anyways? Thanks again.
Corinne Segura, Building Biologist
Without having test results from toaster ovens specifically, I can’t say for sure. Galvanized steel used in other applications like in gardening can have lead. But yeah it won’t vaporize at 450 degrees in a toaster oven.
Carol
Any idea about enamel inside the toaster oven & on tray? I tried googling but not getting anywhere. I am not living in Portugal & I thought Europe was a head of the game for safety, but it is extremely difficult to find out any information from websites & emails are not always answered. Looking for a safe toaster oven or air fryer. Thanks.
Corinne Segura, Building Biologist
enamel is probably another way of describing the ceramic coatings i talk about in the post
Renee Scott
Have you done research on the new toast ovens that are for steam cooking? I am looking for the same info on these ovens….This is a great alternative to stop using microwave ovens.
Corinne Segura, Building Biologist

Amy A.
Thank you for your research! I am wondering where to find safe plates/baskets or items that my family can use to heat up our food on, when it is inside one of these recommended toaster ovens.

hi there which rotisserie oven is most nontoxic on the market and I can accommodate two chickens?
Corinne Segura, Building Biologist
I haven’t look at that size of toaster ovens
Stacey
Hi Corinne, I am so appreciative of the research you have done on these toasters! I am wondering if you ever looked into Zojiyushi’s Micom Toaster Oven ET-ZLC30. I emailed customer service to inquire about the materials in the inside of the oven and recieved the following response:
“The oven interior and parts of the Micom Toaster Oven ET-ZLC30 do not have a non-stick coating.
The oven interior, baking tray, broil tray and mesh rack are made of aluminized steel.
Any materials coming in contact with food and beverages are BPA free and are safe and hygienic.”
This sounds promising but I was curious your thoughts given your expertise!
Corinne Segura, Building Biologist
I wouldnt use aluminum with most foods myself but apart from that yes I would want to avoid the non-stick coatings
Stacey
To confirm, aluminized steel is different that aluminum, correct? would you use galvanized steel over aluminized steel? Thanks!
Corinne Segura, Building Biologist
i have no problem with galvanized steel that is just the addition of zinc. aluminized steel is a layer of aluminum over steel.
Elizabeth
Hello,
Thank you so much for taking the time to do the research on these products.
I came across two models from GE that claim to have stainless steel interiors. They don’t have non-stick coatings. They do have a Prop 65 warning, but they were unwilling to give any detailed information about why there was a warning.
Here are the two models.
G9OAABSSPSS
G9OAAASSPSS
Thanks again!
Corinne Segura, Building Biologist
I mention in the article the common prop 65 chemicals found in toaster ovens
Elizabeth
Thank you for your response. I was just wondering if you had looked at these two models since they are completely stainless inside?
Jenna Lupo
I am so thankful for this article. my almost 3 year old son was diagnosed with autism and we did some heavy metal testing on him and he tested SO HIGH for antimony and I couldn’t figure out why. now I know it was because we used our air fryer to prepare his food every single day, sometimes multiple times a day. Would appear we were slowly poisoning his nerves and could very well be why he experiences neurological delays. I threw my air fryer in the garbage and I pray we can heal with with a good detox. thank you for writing this
Elizabeth
Thank you for your response. I was just wondering if you had looked at either of these models since they are stainless steel inside with no nonstick surfaces.
SG
Hello! I really wanted to buy the Black & Decker toaster oven but wanted to check with the company first on the materials used because sometimes that changes. I reached out to their customer service and they confirmed the zinc coating on the interior but they wouldn’t tell me what the coating is covering, saying it’s “proprietary” – which isn’t very helpful. They also said the trays and bake pan are aluminum.
Corinne Segura, Building Biologist
Thanks, yes i expect the trays to be aluminum and the zinc is almost certainly over steel
Beth
Thanks for this article! I’ve researched toaster ovens oven the years but never came up with a clear solution. Not overly sensitive to off-gassing; just interested in less toxic products. I had an Anova Precision Oven (huge and pricey, but wow, good oven). It’s all stainless, as far as I know. (Someone correct me if not.) I use my own pans. Sadly getting rid of it as I move out of my current place with mold exposure. Link: https://anovaculinary.com/products/anova-precision-oven
Aiming for a more reasonably priced option now to replace it. I was looking at your top rec (HYSapientia) and it looks like they may be going out of business or backordered. Now Google is trying to sell me on the Our Place Wonder Oven instead. The pan is nonstick ceramic, but the internal components say they’re stainless. Has anyone used this Wonder Oven?
https://fromourplace.com/products/wonder-oven?variant=43276070748354

The non stick tray may be of similar composition to their frying pan material which tested as follows: Lead: 34 +/- 6 ppm (safe according to all standards — but not negative, she explains), Chromium: 7,837 +/- 284 ppm, Tin: 23 +/- 6 ppm, Platinum: 206 +/- 26 ppm, Zinc: 1,789 +/- 45 ppm, Copper: 4,965 +/- 87 ppm, Nickel: 615 +/- 41 ppm, Iron: 7,795 +/- 196 ppm, Manganese: 480 +/- 148 ppm, Vanadium: 1,039 +/- 230 ppm, and Titanium: 37,700 +/- 900 ppm.
Dianna Suslo
Is non stick Zinc coating considered non toxic?
Corinne Segura, Building Biologist
if it’s just a zinc coating/galvanized steel that is not a non-stick coating so there is probably something else going on there
Kylie
I’m also looking at the Wonder Oven but just replacing the trays. Would that be a good alternative?
Corinne Segura, Building Biologist
Yes

have you found trays replacements for the wonder oven?
Joshua E
have you?
Danny
Is the 4 slice Black & Decker 4 slice toaster on par with your review of the 8 slice toaster (more space saving)? I notice a metallic chemical smell with so many confection ovens, toaster ovens, hotplates and microwaves. Hoping to avoid this with one of the models you reviewed. Thank you for the helpful info!
Corinne Segura, Building Biologist
Appliances generally have a chemical smell coming from the components in the back in this case. This article isn’t about that odor but mostly about PFAS and aluminum.
Danny
Is the 4 slice Black & Decker 4 slice toaster on par with your review of the version 8 slice toaster? Thank you.
Corinne Segura, Building Biologist
you’d have to see if the materials are the same, they probably are
Janella
I have a Breville convection oven which also broils, toasts, thaws, roasts, & etc.
Sometimes it has a metallic smell when toasting. I wonder about the heating elements, and what appears to be an enamel coated interior. I use parchment paper over the enamel covered pan. Is that safe? Any thoughts? Thank you.
Corinne Segura, Building Biologist
since this is a question for a toxicologist i cannot answer this one, i would expect parchment paper to be a good enough barrier but I’m not positive. Make sure the parchment paper itself is free of PFAS
Nina
Thanks so much for all this research! I just bought a Cuisinart Chef’s Convection oven. Any thoughts on this product? I did research, but I don’t think I covered what I needed to. It can be so hard to know which websites are accurate and which are not. I would love your opinion. I’ll switch it out for another product if need be. It also comes with a tray that I’ve been using, but after reading the comments here, I realize that it must be aluminum. As another reader mentioned, it can be hard to find trays on Amazon that are both definitely safe and fit the product dimensions.
One more question – I’ve recently purchased Green Pan pots and pans (again after doing research). Do you think their products are safe?
Corinne Segura
You can ask them about the factors that i cover in the article.
As for green pan one of testing results and links in the article to ceramic non stick coatings is to them.
Anna A
I recently purchased a Black and Decker toaster oven on your list and noticed that the heating tube in has what appears to be white plastic supports. Are these safe?
Are there any toasters and toaster ovens that have a plastic free interior?
Thank you,
Anna
Corinne Segura
The heating shield over the heating tubes are usually metal. But if there is a hard plastic support in there it’s probably PP or PE. I would consider that safe. There are definitely going to be plastic parts in the hidden parts which also will be heating up from the oven.
Jill
Hello Corinne,
What about the Wonder Oven? It has a stainless steel interior.
Thanks,

Is Gourmia GTF7690 safe? I have been using an Oster and need a new one.
Corinne Segura
you’d have to ask what the baking pans etc are made of.
Nea
Thank you for your quick reply. I never use the pans that come with the oven because usually, they are aluminum. I am just asking about the interior of the oven.
Bec
Hi. Thank you for your research. I’d be happy to buy you a coffee!!
Just wondering if there is just a slot toaster that is all stainless and non toxic? I’ve read many have nonstick interior. We just need something for bagels.
Corinne Segura
i havent written about toasters as most seemed fine to me but maybe i wil write about it in the future
Michelle
Corrine,
Thank you for your research. I have been trying to find a non toxic oven for my daughter! So hard to know what is safe these days. Our families have been working on having chemical free homes. We started 6 years ago!! Thank for knowledgeable people like you!!
I was wondering if you looked at:
1. The New Gourmia 6-Slice Digital Toaster Oven Air Fryer with 19 One-Touch Presets, Stainless Steel:
2. COSORI Air Fryer Toaster Oven, 13 Qt Airfryer Fits 8″ Pizza, 11-in-1 Functions with Rotisserie, Dehydrate, Dual Heating Elements with Convection Fan??
Corinne Segura
only looked at the ones in the post
Patricia
Hello,
Thanks for this great article and all of your research. It’s fantastic! I was wondering about the toaster ovens from Greenpan – the have the Elite and the Bistro. Are those safe?
Corinne Segura
the non stick part of the pans might be similar to their baking tray though that’s not totally obvious. the pan contained 1,220 +/- 200 ppm, Chromium: 126 +/- 59 ppm, Antimony: 66 +/- 40 ppm, Iron: 2,361 +/- 177 ppm, and Titanium: 51,900 +/- 900 ppm
Annie
Do you have suggestions for replacing the baking pan, broiling pan, and tray for the Oster Digital Air Fryer Oven? I looked on Amazon, but it’s hard finding products that will fit this oven. Thanks!
Corinne Segura
I link to a couple options in the article but they are not exactly the full dimensions
Meg
Is the Cafe Toaster Oven safe? It says no teflon is used but still have no idea if its non toxic or not. Would love your help, thank you!
Corinne Segura
i dont know what that black coating is on the baking tray
Sienna
My reply is a bit late but I also emailed Cafe’s customer service about their Couture Oven and this is what they replied:
Interior – Stainless Steel
Heavy-Duty Wire Rack – Steel with Nickel Plating
Baking Tray; 12″ Pizza Pan – Porcelain Enamel
Baking tray does not have a non-stick coating.
The baking tray is free from lead and cadmium.
Air Fry/Dehydrate Basket – Steel with Nickel Plating
Crumb Tray – Aluminum-coated Steel
Hope this helps!
Corinne Segura, Building Biologist
“porcelain enamel” is a non-stick surface, I would verify it’s free of PFAS and nano-metals
Jennifer Laskey
Have you looked at the Wolfe toaster oven?
Corinne Segura
it says it has a non stick interior which is free of only PFOA, that is only one of many PFAS.
Sophia
Is galvanized steel on the inside safe? I was searching for air fryer/counter top oven with stainless steel on the inside but could not find one.
Corinne Segura
yes
Ashley
What about the Our Place new Wonder Oven, which is like a toaster oven / air fryer? They have a lot of strong messaging around being “non toxic” and I was looking into buying one, but I’m curious as to how “non toxic” it really is..
Corinne Segura
under non stick ceramic coatings the first one is the coating used by Our Place: “Lead: 34 +/- 6 ppm (safe according to all standards — but not negative, she explains), Chromium: 7,837 +/- 284 ppm, Tin: 23 +/- 6 ppm, Platinum: 206 +/- 26 ppm, Zinc: 1,789 +/- 45 ppm, Copper: 4,965 +/- 87 ppm, Nickel: 615 +/- 41 ppm, Iron: 7,795 +/- 196 ppm, Manganese: 480 +/- 148 ppm, Vanadium: 1,039 +/- 230 ppm, and Titanium: 37,700 +/- 900 ppm.”
Their oven is super cute, it’s smaller than usual so if you wanted to replace that non stick tray that goes inside you would have to see if you can find one that size.
Cree
Hi Corrine!
Thanks for doing all this work. I had just read an Amazon review of a convection oven with a galvanized steel interior by a bee keeper that said it’s very toxic when heated so I did a search and it seems you can’t heat galvanized steel over 390 F or it gives off very toxic fumes. Search “does galvanized steel give off toxic fumes when heated”. Why don’t they use stainless steel inside?

some of those websites are not good sources.The melting temperature of zinc is 420°C (788°F) and the vaporization temperature is 907°C (1665°F). source https://smokelessfire.com/wp-content/uploads/2021/05/08bf6-tarter2bproduct2bsaftey2breport2b20202b-2bfire2bring28329.pdf
The toaster ovens are only reacting 450 F so it’s no risk there

Have you looked into the Breville Smaet oven Air Fryer? They claim they are stainless steel also. Any help would be appreciated. Thank you!

The baking pan and inside sides are not stainless steel based on the photos.

What are your thoughts on the Ninja air fry countertop oven flip up?

HYSapientia is made in China. Isn’t that a concern in regards to the safety of the material?
Corinne
there are tonnes of issues with lead and other toxins in products made in the US so I don’t avoid products made in China. It’s all about how much attention the company is paying to their materials and production, wherever they are.
