The Ninja Crispi is the most PFAS-conscious mass-market air fryer – it cooks in borosilicate glass containers that Ninja markets as made without PFAS or PTFE, and the crisper plate inside is ceramic-coated aluminum rather than PTFE. For a larger countertop oven, Our Place says its Wonder Oven is made without PFAS, including PTFE. Avoid any 'non-stick' model without explicit PFAS-free claims; the popular Instant Vortex Plus ClearCook, for example, uses a PTFE-coated basket.
Most air fryer baskets ship with PTFE-coated non-stick surfaces. Convenient, yes. But PTFE is a fluoropolymer – part of the PFAS family that includes over 15,000 synthetic chemicals the EPA now classifies as "forever chemicals." When PTFE coatings get scratched or overheated past 500°F, they shed particles directly into your food.
The industry calls this "safe" because intact PTFE is chemically stable. But scratches happen. We've pulled the material specs, brand disclosures, and any published testing we could find for the major air fryer brands sold in the US in 2026. Only a handful of models skip fluoropolymer coatings on the surfaces your food touches, and fewer still publish lab results.

PTFE (polytetrafluoroethylene) is the chemical name for Teflon. It belongs to the PFAS family because it's made from fluorinated carbon chains – the same molecular structure that makes PFAS so persistent in the environment and human body. The EPA considers PFOA (perfluorooctanoic acid), the processing aid long used to make PTFE, a likely human carcinogen.
Internal DuPont documents revealed in litigation showed the company knew for decades that PFOA builds up in human blood. When you heat a PTFE-coated pan or air fryer basket past 500°F, which can happen if you preheat an empty basket on max, the coating starts to break down and release ultrafine particles and fluorinated gases, some of which were not part of the original coating formula.
Even below 500°F, scratched coatings shed. We're not talking about catastrophic flaking – the damage is microscopic. And PTFE is the default: the Ecology Center's 2020 "What's Cooking?" study found PTFE coatings on 79% of the nonstick cooking pans it tested (Ecology Center).
The industry defense: "PTFE itself is inert." True, but irrelevant. You're not eating pure PTFE. You're eating the breakdown products, the manufacturing residues (PFOA, GenX, PFBS), and the particles abraded by metal tongs.
Price: $129–$149 Capacity: 4 quarts (serves 2–3) Cooking surface: Borosilicate glass containers + ceramic-coated aluminum crisper plate PFAS-free source: Ninja's product page states its CleanCrisp glassware is made "without forever chemicals – PFAS and PTFE"; the crisper plate uses a ceramic (sol-gel) coating, not PTFE
Instead of a PTFE-coated basket, the Ninja Crispi cooks in stackable borosilicate glass containers with a removable crisper plate that sits inside. The containers are glass; the crisper plate, where food actually rests, is aluminum with a ceramic (sol-gel) coating, per independent reviews such as Prudent Reviews. That is a real improvement over Teflon, but it is still a coating, so treat the plate like any ceramic surface: no metal utensils, no abrasive scrubbing.
The glass containers double as storage and go in the dishwasher. A light spray of a high-smoke-point oil such as avocado oil helps keep food from sticking to the ceramic plate.
Drawback: Small capacity. Four quarts is fine for two people or small batches. If you're cooking for a family of four or more, you'll need to work in batches. There's also a learning curve – the two-bowl system requires slightly more setup than dropping food in a basket.
Price: $195–$225 Capacity: 13 quarts (countertop oven) Cooking surface: Stainless steel interior, chromed steel basket and rack, ceramic-coated aluminum bake pan PFAS-free source: Our Place's product page says the interior and included accessories are made without PFAS, including PTFE (Our Place); we did not find a published third-party lab report there
Our Place built their brand on non-toxic positioning. The bake pan's ceramic coating is a sol-gel type finish, not a fluoropolymer, and the rest of the food-contact parts are uncoated metal. Ask Our Place for third-party test documentation before buying if you want more than the brand's statement, and confirm it covers short-chain compounds, not just PFOA and PTFE.
The oven itself is a 6-in-1: air fry, bake, broil, roast, reheat, dehydrate.
Drawback: Ceramic coatings, even well-documented ones, are less durable than stainless steel. If you scrub the bake pan with abrasive sponges or use metal utensils on it, you'll eventually wear through the coating. Use silicone or wood utensils on the ceramic pan. That's reasonable, but it's maintenance. The Ninja Crispi's crisper plate is also ceramic-coated, so the same care applies there; only its glass containers are coating-free.
Price: $399–$449 Capacity: 1 cubic foot (fits a 14-lb turkey) Cooking surface: Interior walls with a non-stick coating, two wire racks, air fry basket, enamel roasting pan, non-stick pizza pan PFAS-free source: Breville's manual says the interior walls have a "non-stick coating" but does not name it (Breville manual); Mamavation's review reports the food-contact coatings are silica-based rather than PTFE (Mamavation)
If you want a full-size toaster oven that doubles as an air fryer, the Breville Smart Oven Air Fryer Pro is the high-capacity pick. It is not a bare-steel oven: the interior walls are non-stick coated, and the kit includes a non-stick pizza pan. We could not find a Breville statement that names the coating or calls it PFAS-free, so we rank it below the Crispi and Our Place. Cook on the wire racks, the air fry basket, or the enamel roasting pan, and skip the non-stick pizza pan if you want to minimize coated contact.
Breville's super-convection setting is what handles air frying, and the large cavity means bigger batches than any basket model on this list.
Drawback: Price. At $400+, this is an investment. And it's a countertop toaster oven – it takes up space. If you already have a toaster oven and just want to add air frying, this makes sense. If you only need an air fryer, the Ninja Crispi costs a third as much and has the clearer PFAS statement.
Price: $199–$229 Capacity: 0.6 cubic feet (fits a 12-inch pizza) Cooking surface: Nonstick interior, included air fry basket, baking pan, and grill/griddle PFAS-free source: Not confirmed. Cuisinart describes the TOA-70 interior as nonstick without naming the coating, and Cuisinart discloses PFAS in its nonstick lines
The TOA-70 is Cuisinart's mid-range toaster oven with an air fry function and an included air fry basket. We originally listed it as a stainless option, but Cuisinart markets the interior as nonstick, and we could not find a statement that the coating or the included accessories are PFAS-free. If you buy one, an uncoated stainless steel replacement basket keeps food off the coated surfaces.
Cuisinart rates the interior for a 12-inch pizza. That is a bit over half the Breville's capacity, but still enough for a family meal.
Drawback: No PFAS-free documentation, a step down from the Breville in capacity and features, and as a countertop toaster oven it takes more space than a pod-style air fryer.
Price: $129–$159 Capacity: 6 quarts Cooking surface: Nonstick-coated aluminum basket PFAS status: Reviewers who checked Instant's cookware chemical disclosures report that the ClearCook is on Instant's list of models with a PTFE-coated cooking surface, and that Instant discloses PTFE, PFA, and FEP fluoropolymers for its Vortex line (Mamavation)
An earlier version of this guide listed the ClearCook as a certified ceramic model. We could not find any SGS report or PFAS-free claim from Instant for it, so we've corrected that. The ClearCook name refers to the viewing window, not the coating. Instant does sell a PFAS-free ceramic Vortex Dual in the UK, but we could not confirm a US equivalent.
Drawback: It's a PTFE basket. If you already own one, cap the temperature at 400°F, never preheat empty, and replace the basket once it scratches.
Price: $119–$139 Capacity: 6.8 quarts Cooking surface: Ceramic-coated basket (ceramic version only) PFAS-free source: Retailers sell a "DualBlaze 6.8QT with Ceramic Coating" version (Best Buy); we found no published lab report for it
Be careful with the model name. The standard Cosori Pro III Dual Blaze ships with a nonstick basket that is marketed as PFOA-free, not PFAS-free, and Cosori is among the brands that disclose PFAS in their air fryers. Only the version sold as "with Ceramic Coating" uses a ceramic basket. Cosori's separate Iconic model is sold with a basket Cosori itself calls "PFAS-free ceramic-coated" (Cosori).
We can't fully verify the ceramic Pro III's coating without third-party testing. If you're okay with some uncertainty, it's a reasonable option. If you want zero doubt, go with the Ninja Crispi or Our Place Wonder Oven.
Drawback: No independent test report, and the PTFE and ceramic versions look alike, so check the listing title. Like any ceramic coating, it will wear faster with metal utensils or abrasive scrubbing.
These are the red flags that mean "contains PFAS" even if the marketing says otherwise:
Any air fryer marketed as 'non-stick' without explicit PFAS-free certification. Non-stick means PTFE unless proven otherwise. Philips, for example, states that its airfryer baskets are mostly coated with PTFE (Philips). Many other brands simply say "nonstick" and leave it there, which usually means PTFE.
Imported models with no English-language material spec sheet. If you can't find a clear list of what the basket is made from, assume PTFE. Unbranded budget models with no named manufacturer rarely publish material specs at all.
Used air fryers with visible scratches on the basket. Even if the original coating was PFAS-free ceramic, a scratched coating exposes the aluminum substrate underneath. Aluminum itself isn't dangerous, but you're losing the benefit of the ceramic layer. And if it's a PTFE coating (most used models are), you're cooking on degraded fluoropolymer.
'PFOA-free' claims without PTFE/PFAS testing. PFOA is one PFAS compound out of 15,000. Brands that say "PFOA-free" but don't mention PTFE are usually still using PTFE – they've just switched to a different manufacturing process that doesn't use PFOA as a processing aid. You're still getting fluoropolymer in your food.
For every model on this list, we relied on the materials and PFAS statements manufacturers publish on their spec sheets and product pages. For ceramic-coated models, we looked for lab reports or explicit brand statements; where we found only marketing claims, we say so in the listing.
We did not run hands-on cooking tests, so these picks rank materials and published PFAS documentation, not cooking speed or crispness. Expect to use a light oil spray on any uncoated or ceramic surface to prevent sticking.
Ceramic coatings can be PFAS-free, but they wear out. Silicon dioxide (the base of most ceramic coatings) is chemically stable and non-toxic, but the sol-gel process that bonds it to aluminum isn't perfect. Over time, utensils and scrubbing degrade the coating. Once it's worn through, you're cooking on aluminum.
Stainless steel and glass don't degrade. A stainless steel basket from 2020 cooks the same way in 2026. Glass doesn't scratch or react with food. That's why the Ninja Crispi is the top pick – its glass containers are coating-free, and the only coated part is a replaceable ceramic crisper plate.
If you prefer a larger countertop oven, the Our Place Wonder Oven has a stainless interior and a brand statement that it's made without PFAS. For a basket model, look for a ceramic coating the brand explicitly calls PFAS-free, such as Cosori's Iconic, and expect the coating to wear over a few years.
PFAS doesn't just come from cookware. According to our analysis of the EPA's UCMR5 data (2023-2025), about 34% of US public water systems tested had detectable PFAS – most of it from industrial discharge, military firefighting foam, and manufacturing plants. The same PFOA that used to be in Teflon production (phased out by 2015 but still persistent in groundwater) still shows up in drinking water across the country.
If you're switching to a PFAS-free air fryer to reduce exposure, check your water too. We built a free tool that shows PFAS contamination levels by zip code using EPA data: check your water quality. For more on how water filters handle PFAS, see our water filter comparison guide.
Buy the Ninja Crispi if you cook for 1-3 people and want the least PFAS-prone design. Its glass containers are made without PFAS or PTFE, and the crisper plate is ceramic, not Teflon.
Buy the Our Place Wonder Oven if you want a larger countertop oven with a stainless interior and a brand statement that it's made without PFAS.
Buy the Breville Smart Oven Air Fryer Pro if you want a premium toaster oven that doubles as an air fryer, you're willing to pay for it, and you're comfortable with a non-stick interior coating that reviewers report is silica-based rather than PTFE.
Avoid anything marketed as "non-stick" unless it comes with third-party PFAS testing. And if you're concerned about PFAS exposure more broadly, start with your drinking water – that's where most people get the highest dose.
Is the Ninja Crispi actually PFAS-free? Ninja states that its CleanCrisp glass containers are made without PFAS and PTFE. Food sits on a crisper plate that is aluminum with a ceramic (sol-gel) coating rather than PTFE, according to independent reviews. So the design avoids fluoropolymer coatings, but the plate is still a coated surface that wears with metal utensils and abrasive scrubbing.
Are ceramic-coated air fryers safe? It depends. Most ceramic coatings are synthetic sol-gel formulas (silicon dioxide base) that don't contain PFAS if properly manufactured. But only buy models with third-party PFAS testing or an explicit brand statement. Our Place says its Wonder Oven is made without PFAS, and Cosori calls the Iconic's ceramic basket PFAS-free. Note that the Instant Vortex Plus ClearCook is not ceramic; it uses a PTFE basket. Generic ceramic claims without documentation aren't trustworthy.
What's wrong with PTFE if it's stable below 500°F? PTFE is chemically stable when intact, but scratching releases particles into food even below 500°F. And PTFE is everywhere: the Ecology Center's 2020 "What's Cooking?" study found it on 79% of the nonstick cooking pans it tested (source). The EPA also classifies PFOA, a precursor chemical used in PTFE manufacturing, as a probable carcinogen. PTFE is PFAS chemistry – it belongs to the same fluorinated carbon chain family.
Can I use parchment paper to avoid the coating? Parchment paper helps reduce direct contact, but it doesn't fully shield from particles abraded off a scratched basket. Air circulation in an air fryer pulls particles upward through the perforations, and parchment doesn't stop that. It's a partial solution, not a fix. If your basket coating is visibly scratched, replace the basket or switch to a PFAS-free model.
Do I need to season a stainless steel air fryer basket? No. Unlike cast iron, stainless steel doesn't need seasoning. Just use a light spray of high-smoke-point oil (avocado, grapeseed, or refined coconut) on the basket before cooking to prevent sticking. Clean it with dish soap and a non-abrasive sponge after each use. Ceramic-coated plates like the Ninja Crispi's work the same way – spray, cook, wash gently, repeat.
Replacing the air fryer is the easy part. Most kitchens still have a PTFE-coated skillet or two hiding in the cabinet. A few next reads:
