Stainless steel air fryers: the stainless is usually the outside

An air fryer called “stainless steel” usually has a stainless housing. The basket your food sits in is a different part, and on most models we checked it is coated — sometimes stated, sometimes not mentioned at all.

What the score is, before you read one

It is a disclosure score out of 100, not a safety rating: what it is made of, who tested it, where it is made, whether the claim matches the evidence. A product can score 20 and be perfectly fine to cook in. What a low score means is that nobody outside the company can check. The rubric is here.

The short answer

We have not found an air fryer in our data that is sold as stainless steel and states a bare stainless cooking basket. The closest uncoated option we have scored is the Fritaire (81/100), which is a glass bowl with bare 304 stainless accessories — sold as a glass air fryer, not a stainless one.

The Cosori Iconic Stainless Steel names 304 and 430 stainless for the structure and exterior, and its own page says the basket is “ceramic-coated, nonstick”. The Chefman TurboFry Touch “Stainless-Steel” gives the basket only as “nonstick basket”. In Australia, Kogan’s 10L XXL lists “Polypropylene & Stainless Steel 304” as its material, which describes the exterior.

The one-line rule

Read the line about the basket or crisper plate, not the product name. On every model sold as stainless that we checked, the basket is coated or not described.

Sold as the stainless steel air fryer. The stainless is the housing. Cosori’s own page says the basket is “ceramic-coated, nonstick”.

If you were buying this to get away from coatings, read the product page twice — the answer is in there, just not in the name.

  • What touches the food — 8/60. The stainless steel is the housing finish. The basket is given only as “nonstick basket” — no substrate, no chemistry, no claim
  • The rest of it — 13/25. Lids, seals, handles and the outside.
  • Backed up — 6/15. Named testing, published reports, and whether the claim matches the evidence.

  • They claim. None made — the page carries a Prop 65 cancer and reproductive harm warning
  • Warranty. One year
  • Heat. 400°F / 205°C; top-rack dishwasher safe basket

The textbook case of the trap. The model name says stainless steel; the surface your food touches is an unnamed nonstick coating.

A buyer scanning model names would get this wrong, and it is the same pattern we found on the Cosori Iconic Stainless Steel and the Instant Vortex Plus Stainless Steel.

Nuwave Brio Plus 7 qt — 54/100 · coated, or plastic in contact

Nuwave Brio Plus 7 quart air fryer in black with a stainless front panel and the basket pulled out
Maker’s product photo
  • What touches the food — 26/60. “PFAS-free ceramic basket” with a “100% non-toxic, all-metal interior” — substrate under the ceramic not named, chemistry not named
  • The rest of it — 17/25. Lids, seals, handles and the outside.
  • Backed up — 11/15. Named testing, published reports, and whether the claim matches the evidence.
  • Made in. UNVERIFIED — not published
  • They claim. "PFAS-free ceramic basket"; "100% non-toxic"
  • Warranty. One year manufacturer’s warranty
  • Heat. 50°F to 400°F; ceramic non-stick base tray dishwasher safe

Nuwave’s own AB 1200 page names PTFE and FEP in Brio air fryer baskets — annotated, in their words, “PTFE coating in tray and basket”.

This model is not on that list, so the PFAS-free claim is not directly contradicted. But the Brio line is split down the middle and the product pages do not tell you which half you are buying.

Kogan 10L XXL Digital Air Fryer — 17/100 · coated, plastic, or unnamed

  • What touches the food — 0/60. “Polypropylene & Stainless Steel 304” — describes the exterior; basket not stated
  • The rest of it — 17/25. Lids, seals, handles and the outside.
  • Backed up — 0/15. Named testing, published reports, and whether the claim matches the evidence.
  • Made in. UNVERIFIED — not published
  • They claim. No claim of any kind
  • Warranty. 1 year
  • Heat. Not published

This is the trap worth learning. The material field says “Polypropylene & Stainless Steel 304”, and a shopper reasonably reads that as the basket.

It is not. Read in context — “Premium stainless steel design. Durable stainless steel complements any kitchen” — the 304 is the outside of the box. The basket is never described at all.

How to check a listing yourself

  • Find the line about the basket or crisper plate, not the product name or the “material” spec row.
  • “Nonstick” on a basket means a coating. If the chemistry is not named, you cannot tell which kind. What “PTFE-free” doesn’t tell you.
  • A PFAS-free claim on the basket is worth more than one on “the product”, and an unqualified claim is worth more than “no intentionally added”.

Our verdict

Treat “stainless steel” in an air fryer’s name as a description of the outside. If an uncoated cooking surface is what you are after, the strongest written answer in our data is a glass model. Glass air fryers, compared.

Questions people ask

Is there a fully stainless steel air fryer with no coating?

Not in the products we have scored so far. Every model sold as stainless that we checked either coats the basket or does not say what the basket is. We will add one if a maker puts a bare stainless basket in writing.

Is the Cosori stainless steel air fryer non-toxic?

Cosori says its “cooking surfaces [are] free of PFAS and BPA”, and its page also says the basket is ceramic-coated. The ceramic’s chemistry is not published. It scores 47/100.

Are stainless steel air fryers safer than non-stick ones?

The stainless parts usually do not touch food, so the name alone tells you little. What matters is the basket and plate, which is what our “what touches the food” score covers. Our score measures disclosure, not safety.
