Questions and Answers About Stainless Steel Air Fryers

Where should I start?

Pick the question closest to yours.

Is this air fryer really stainless? The word can mean the outside, the inside walls or, rarely, the basket. See is there an all-stainless air fryer? and which air fryers have a stainless basket?. The material table shows every model.

What does a word on the label mean? “Non-toxic”, “PFAS-free” and “ceramic” promise less than they sound like. See “non-toxic” on a label and “PFAS-free”, brand by brand. The glossary explains the words.

Is it a health question? We report what the FDA, EPA and Poison Center say, in their words. Start with are air fryers toxic?. For your own health, ask your doctor.

Is it about one brand? Brand pages report that brand’s documents and don’t rank it. If yours isn’t there, how to check an air fryer’s coating works for any model.

Is it about a new or worn air fryer? See the smell of a new air fryer and a peeling coating.

What are the limits of these answers?

We can’t give you a list of “safe” models, because no source we read backs that word for an air fryer. We can’t speak for a model we haven’t read. When a page says we found nothing, that means nothing in what we could read. If your model isn’t named, check the model number on the label and read the brand’s manual for it. If it’s silent, ask the brand in writing.

All questions

• How to Tell if My Air Fryer Is Toxic: Check the CoatingYou can't measure toxicity at home, and neither can we. You can find out what the coating is. Get your exact model number, search the manual for “coating”, “nonstick” and “ceramic”, then look for the brand's California AB 1200 list. If those say nothing, ask support in writing. A quiet manual doesn't prove there is no coating.
• What Is a Nonstick Air Fryer Basket Made Of?Most nonstick air fryer baskets we read about are metal with a nonstick layer on top. Cosori's TurboBlaze manual says aluminum with a nonstick coating, and Typhur lists aluminum alloy with a ceramic coating. Our Place lists chromed steel, and Ninja's Crispi uses a glass bowl. Many brands don't name the metal, so check your own model.
• PFOA-Free Air Fryer? Why That Isn't “PFAS-Free”No, they aren't the same. PFOA is one PFAS, and the EPA says there are thousands of PFAS chemicals. A PFOA-free label doesn't tell you whether the coating is PTFE. An older Cosori support page even describes a “PFOA-free, BPA-free Teflon coating”. To find out what you're buying, ask the brand which coating is on the basket.
• Are Air Fryers Toxic? What the Sources SayNo source we read calls air fryers toxic. On cancer, the National Capital Poison Center says air-frying equipment “is not known to” cause it. The FDA says studies show a negligible amount of PFAS capable of getting into food from nonstick coatings. That page does not cover fumes, damaged coatings or air fryers, so some questions stay open.
• Do Air Fryers Have PFAS? What Each Brand SaysSome do. Ninja's list names PTFE, a type of PFAS, for many air fryers made before 15 August 2024. Philips and Tefal confirmed PTFE for models checked in Europe. Some brands say their coating is made without it, and many say nothing at all. It depends on your model and when it was made, so check your model number.
• Do Air Fryers Have Teflon? How to Check Your ModelSome do, by the brands' own lists. Ninja's list names PTFE, the material sold as Teflon, for units made before 15 August 2024. Cosori's August 2026 list names it for many models and leaves it off others. Some brands say “nonstick” without saying which coating. Check your model number, not only the brand.
• Do Air Fryers Cause Cancer? What the Poison Center SaysThe National Capital Poison Center says “Air-frying equipment is not known to cause cancer.” The worry comes from acrylamide, which can form in food cooked at high heat. The Center says it is considered a probable human carcinogen based on animal studies, and that there is “no conclusive evidence” linking it in food to cancer in people.
• Is PTFE Safe in an Air Fryer? What the FDA SaysThe FDA says some PFAS are approved for nonstick cookware coatings, and studies show a negligible amount capable of getting into food. That page doesn't cover fumes, damaged coatings or air fryers. Overheating is a separate question. A medical review names overheated coated cookware as a common way people are exposed to fumes. We found no air fryer measurement, and we don't call PTFE safe or unsafe.
• Is a Ninja Air Fryer “Non-Toxic”? What Ninja's List SaysWe don't use that word for any product. Ninja's California list, dated April 2025, names PTFE and aluminum for many air fryer series made before 15 August 2024. For several series made after that date or bought after 1 January 2025, it names aluminum alone. Ninja itself uses “Non-Toxic” in the title of its glass air fryer page. Check your unit's series and date.
• Is There a “Bird Safe” Air Fryer? What Vets and Brands SayWe can't name one, because no source we read clears an air fryer for a home with birds. The Merck Veterinary Manual says PTFE gas poisoning “occurs commonly in pet birds housed in or near kitchens”. PTFE is the coating sold as Teflon. We found no study that names an air fryer, so please ask your bird vet and the brand.
• Is a Cuisinart Air Fryer “Non-Toxic”? What the TOA-70 Booklet SaysWe don't use that word for any product. The Cuisinart TOA-70 Series booklet says “The sides of the oven are coated”. It names no coating and doesn't say what the basket is made of. “No intentionally added PFAS” reached us only as a page excerpt, so we can't count it. Ask Cuisinart in writing which statement covers your unit.
• Is Stainless Steel Non-Toxic? What One Study FoundWe don't use that word for any material. One study measured nickel up to 26 times higher and chromium up to 7 times higher in tomato sauce after six hours of simmering at 85 °C (185 °F) in a stainless pot. That is acidic sauce in contact for hours. We found no air fryer measurement. If you have a nickel allergy, ask your doctor.
• Is a Glass Air Fryer Safe? Breakage, Heat and Coated PlatesWe don't make that call. Ninja's guide says “Sudden temperature changes can break glassware”. Its top setting is 450°F, and a Fritaire guide says 400°F. The bowl is glass, but the plate, lid and handles can be something else, so check each model. We found no breakage numbers for any brand.
• Is Ceramic Coating Safe on an Air Fryer? What We Could and Couldn't FindWe can't say, and no source we read settles it. We found no study comparing ceramic with PTFE, and no measurement in an air fryer basket. “Ceramic” is a different kind of coating, not a bare surface. Words like “non-toxic” on these coatings belong to the brand. Follow your manual, and ask your doctor about personal health worries.
• Is the Cosori Air Fryer “Non-Toxic”? What Cosori SaysWe don't call any air fryer that. Cosori's TurboBlaze manual says the basket and plate are aluminum with a nonstick coating. The Iconic's European manual names a ceramic coating. Cosori's August 2026 chemical list shows PTFE for many models, and for one version of the TurboBlaze but not another. Check your exact version with Cosori.
• Is the Gourmia Air Fryer “Non-Toxic”? What the Manual SaysWe don't call any air fryer that, and we have no lab. Gourmia's GAF846 manual names a “nonstick coating” and warns about cooking spray and metal utensils. It names no chemical and no basket material. We couldn't tie that manual to the 8 Qt on Amazon, so that model stays Not confirmed.
• Are Bella, Breville, Chefman, Our Place and Instant “Non-Toxic”?We don't call any air fryer that. Bella's page describes a ceramic nonstick coating on one model. Chefman's list names a “PTFE coating” for some models. Breville's and Instant's manuals name a nonstick coating without saying what it is. Our Place lists a chromed steel basket and a coated bake pan. Each statement covers named models, so check yours.
• Can You Put Glass or Ceramic Dishes in an Air Fryer?It depends on the dish and the air fryer, so check both sets of instructions. Pyrex says its glass “cannot be used in an Air Fryer”. Our Place says ceramic or glass dishes in its Wonder Oven must be oven safe, and Gourmia mentions an “oven-safe dish”. We run no tests, so if either brand says no, leave that dish out.
• Nickel Allergy and Stainless Steel Air Fryers: What We FoundWe found no measurement in an air fryer, so we can't answer for your model. One study measured nickel up to 26 times higher in tomato sauce after six hours of simmering at 85 °C (185 °F) in a stainless pot. That is acidic sauce in a pot, in contact for hours. If you have a nickel allergy, ask your doctor.
• Can You Put Metal or Stainless Steel in an Air Fryer?Often yes, for a heat-safe metal pan or dish with room around it. Cosori, Breville and Cuisinart ask for extra care with containers that aren't metal or glass, which suggests metal is expected. Metal tools inside are ruled out, foil rules differ, and several brands warn against third-party extras. Our Place is stricter, so check your manual.
