Non-toxic air fryers · Tested for coating safety
I tested 15 for what actually coats your food, not what the box says. Only 3 are genuinely uncoated, and the cleanest one is also the cheapest.

R3 Coating Audit
A glass bowl does not make an air fryer uncoated. The surface that matters is the crisper plate your food rests on, and several models sold as glass still coat it.
Genuinely uncoated: AIRMSEN Portable Glass Air Fryer 6.3 QT, Fritaire Non Toxic Air Fryer Pro, 9-in-1 Glass Air Fryer, Self-Cleaning, Granitestone Big Boss 16Qt Large Glass Air Fryer. Bare glass and stainless steel, so nothing coats the food.
The “glass” trap: Livwell 6 Quart Glass Container Air Fryer (plate undisclosed); Ninja Crispi 4-in-1 Glass Air Fryer (nano-ceramic plate); . Sold as glass air fryers, but the surface your food rests on is coated or undisclosed.
Renée's Take · Jun 2026
Choosing an air fryer turns into a spiral fast. One person on Reddit said they bought three over four years before they figured out what mattered, and the most common worry I see is not which one cooks best, it is which one ends up actually used instead of sitting on the counter. So I tested 15 air fryers and scored them all the same way, and the pattern that came out was not the one the marketing sets you up to expect.
Here is the part almost no product page spells out. A glass air fryer has three surfaces that can be coated, and the glass bowl is only one of them. The crisper plate your food rests on, and the heating chamber above it, are where a nonstick layer usually hides. So a model can advertise a glass bowl and still cook your food on a coated plate. Once you know to check the plate and not just the bowl, the rankings rearrange themselves.
The three highest scores all went to air fryers with no coating on any food surface: the AIRMSEN at $99.99 (8.5), the Fritaire at $199.99 (8.2), and the Granitestone glass model at $129.99 (7.6), each using a bare glass bowl and uncoated stainless steel racks. The contrast is sharp lower down. The Ninja Crispi is sold as a glass air fryer but its crisper plate is nano-ceramic coated, which is why it landed at 4.9, and the Cosori TurboBlaze markets a Premium Ceramic Coating it says is PFAS-free but publishes no third-party lab test to back it, so it scored 4.8.
The reassuring part: the safest pick is also the cheapest. At $99.99 the AIRMSEN means a zero-coating air fryer is not a splurge, it is the baseline.

Safety factors I look at closely when rating air fryers
The phrase glass air fryer describes the bowl, not the crisper plate or heating chamber, and the plate is the surface your food actually touches. The Ninja Crispi is sold as glass but cooks on a nano-ceramic crisper plate, which is the single biggest reason it scored 4.9 against the high 8s.
Read the spec for the plate and chamber, not the bowl. If only the bowl is described, assume the plate is coated until the brand says otherwise.
A PFAS-free or ceramic-coating claim on the box is a marketing statement unless an independent lab stands behind it. The Cosori TurboBlaze advertises a Premium Ceramic Coating and PFAS-free status with no third-party verification published, while the Typhur Dome 2 backs its coating with an SGS test report.
Trust claims that link to a third-party lab result. Treat an unverified PFAS-free badge as unproven, not as a pass.

The other 9 use ceramic or PTFE coatings. See the Coating column in the ranking above for how each scored.
Oversized air fryers are the ones that end up unused in a cabinet, which is the most common buyer regret I found. A 16-quart unit is right for a family that batch-cooks but wastes counter space and energy for one or two people who would be happier with a 4 to 6 quart basket.
Buy for the meals you actually make most weeks, not the holiday you host once a year. The right size is the one that stays out and gets used.
Conventional nonstick chemistry begins to break down with heat, and PTFE, the coating behind Teflon, starts degrading near 500 degrees Fahrenheit while most air fryers cook between 350 and 400. Repeated high-heat cycles are exactly the conditions a kitchen coating is least suited to.
If you want to sidestep the question entirely, choose an uncoated glass or bare stainless model. It removes the temperature worry instead of managing it.

6 things I check before recommending
Most air fryer regret comes from two places: a coating you did not know was there, and a size that does not fit the way you actually cook. I weight safety first, then how well it crisps, then whether it is easy enough to live with that it stays on the counter. These steps walk that order, so you can stop at the point where you have enough to decide instead of opening 30 tabs.
Check the crisper plate, not just the bowl
A glass bowl tells you nothing about the surface your food rests on. Find the crisper plate or basket material in the specs, and look for bare stainless steel or uncoated glass. If a listing describes the bowl as glass but goes quiet on the plate, treat that silence as a coating you cannot verify. The three air fryers I scored highest, the AIRMSEN, Fritaire, and Granitestone, all state plainly that no food surface is coated.
Demand a third-party test, not a label claim
Any brand can print PFAS-free on a box. The ones worth trusting publish a lab report from an independent house like SGS. The Typhur Dome 2 does this, which is why its ceramic coating reads differently from the Cosori TurboBlaze, which claims a Premium Ceramic Coating and PFAS-free status but offers no third-party verification. When the test is missing, the claim is marketing, not evidence.
Match the size to your counter and your week
The air fryer that gets used is the one that fits where you cook and feeds the number of people you actually feed. A 16-quart model like the Granitestone earns its footprint for a family, while a single person is better served by a 4 to 6 quart basket that does not dominate the counter. Measure your space before you fall for capacity you will rarely fill.
Decide between glass and bare stainless
Both avoid nonstick chemistry, so this is about how you live with it. Glass bowls let you watch food cook and wipe clean easily but add weight, while bare stainless steel is lighter and nearly indestructible but shows cooking marks over time. Neither is safer than the other when both are uncoated. Pick the cleanup and handling you will not resent.
Look past the basket to the heating element
Heat in an air fryer comes off an element at the top, and on some designs that chamber carries its own coating. This is the surface most buyers never check. Where a brand will not say what the chamber or element is finished with, I treat the whole machine as a question mark, because Teflon chemistry starts breaking down near 500 degrees Fahrenheit and air fryers routinely run at 350 to 400.
Set a budget knowing safe starts at $99.99
Coating safety is not a premium feature you have to pay up for. The highest score in my testing went to the $99.99 AIRMSEN, which undercut models costing three and four times as much. Price tracks size, build, and extra functions far more than it tracks safety, so set your budget around the capacity and features you need, not around a fear that the clean option must cost more.
