Best Non-Toxic Air Fryers
Last reviewed September 2026
Countertop convection fryers - and the honest question of whether any of them are actually plastic-free.
The short answer
Basket air fryers are the problem: the food sits directly on a coating that gets scraped at 400F. Almost every "PFAS-free" model just swaps PTFE for a ceramic sol-gel coating, which is still an applied coating that wears - including the ones marketed on glass, since both the Ninja Crispi and Cuisinart ClearView still rest food on a coated crisper plate. The way out is the oven route. Our Place's Wonder Oven is the least-compromised pick because its air-fry basket is bare chromed-steel mesh with no coating at all, and the NuWave combi steam oven gives you a bare stainless cavity with steel accessories. With any toaster-oven hybrid, swap the bundled basket for a stainless tray.
Why plastic matters in air fryers
Air fryers are the single most contentious appliance for plastic-free and non-toxic kitchens. The default model uses a PTFE (Teflon) nonstick coating on an aluminum basket, and that basket runs at 400F+ - right where fluoropolymer coatings degrade and shed PFAS - with food tumbling against it and scraping it every use. "PFAS-free ceramic" baskets are a real improvement over PTFE, but they're still an applied coating that wears out. The good news, and the reason this category is worth a close look, is that a growing handful of models now use a tempered-glass basket or bowl over a bare stainless plate/rack - a genuinely coating-free food path in a real air fryer. Those are what we lead with; a convection or toaster oven with a stainless tray remains the fallback.
What to look for in air fryers
- The basket coating is everything - avoid PTFE/Teflon; ceramic (sol-gel) is better but still a coating
- Glass-basket / glass-bowl models with a bare stainless plate or rack are the truly coating-free option - and there are now several
- Check what food actually rests on - a "glass" air fryer can still put food on a coated crisper plate (e.g. Ninja Crispi, Cuisinart ClearView). If it does, an aftermarket bare 304-stainless crisper plate is the dominant community swap to make the food path coating-free
- Watch out for silicone lid or basket seals - silicone can shed siloxanes above ~200C, a real concern for strict purists even when the food surface itself is clean
- A coating-free food surface is not a coating-free hot-air path - the internal convection ducting and heating chamber on nearly every unit (glass models included) is ceramic-coated or painted, so "coating-free food path" does not mean coating-free air
- Basket-style units concentrate heat and scraping on the surface more than oven-style ones
- A convection or toaster oven with a stainless tray is the coating-free fallback if you don't want a dedicated gadget - and it is the most reliable route
Recommended air fryers
Every product here we'd actually suggest — best-in-class picks first, then the rest by how plastic-free they are.
Combi Steam Oven
A bare-stainless-interior combi steam/convection oven with stainless accessories and a borosilicate glass pot - a coating-free oven-route way to air fry, with no nonstick cavity.
ClearView Glass Basket Air Fryer (AFC-4)
A PFAS-free glass basket you can cook, serve, and store in - but food rests on a PFAS-free ceramic nonstick crisper plate, so it is a ceramic-coating option, not coating-free.
Crispi Glass Air Fryer
Borosilicate-glass cooking containers with no PTFE - but food still sits on a nano-ceramic-coated aluminum crisper plate, so it is not fully coating-free.
Foodi Digital Air Fry Oven (SP101)
A capable flip-away air-fry toaster oven with a bare-metal interior - but its bundled air-fry basket is Teflon-coated, so it is only a clean choice if you cook on a stainless tray or swap in a stainless mesh basket.
TOA-70 Air Fryer Toaster Oven with Grill
Stainless-look toaster oven, but the bundled air-fry basket and the grill/griddle plate are nonstick-coated. Only worth it if you swap in your own stainless tray - otherwise the food sits on coatings.
TurboBlaze Air Fryer
A basket-style air fryer with a PFAS-free ceramic (sol-gel) coating instead of Teflon. Better than a PTFE basket, but still an applied coating that food scrapes at 400F+ - the Caraway situation, in appliance form.
Wonder Oven
An oven-style air fryer whose air-fry basket is bare chromed-steel mesh (no coating) - the least-compromised way to air-fry. The included bake pans do use Our Place's ceramic coating, so use the basket, skip the pans.

Air fryers to avoid
Popular options that look plastic-free but aren't — and whole categories worth skipping.
WILLOW Eco Series Glass Air Fryer
The coating-free glass-and-stainless food path is real and the brand is legitimate (sold at Macy's, tested by Consumer Reports), but the durability record is poor - Amazon flags it a "Frequently returned item" (16% 1-star) with a recurring pattern of the glass basket cracking in normal use and warranty claims being denied. We document it, but can't recommend a glass basket that cracks. For a coating-free air fry, see the oven route (Wonder Oven / TOA-70) or the Ninja Crispi with a stainless plate.
Boswell Glass Air Fryer 7.5QT
The glass-and-stainless food path may be coating-free, but "Boswell" is not a real manufacturer - boswellairfryer.com is an AI-generated Amazon-affiliate page, and the fryer is a churned third-party listing (multiple near-identical ASINs, seller "CUCOL") with a documented dead-in-4-5-months failure pattern. We document it so shoppers who find it know what it is; for a glass air fryer the community actually vets, see the Ninja Crispi (with a stainless plate).
Fritaire Non-Toxic Glass Air Fryer
Genuinely coating-free food path (tempered glass + 304 stainless), but reliability and QC are poor for a $$$ one-product brand - DOA units, steam-killed touchscreens after a few months, flimsy build and hinge, grease leaks, and only mediocre crisping. We document it for its materials but can't recommend it; for a coating-free air fry see the oven-route picks (Our Place Wonder Oven / Cuisinart TOA-70) or the glass-basket options.
Ninja Air Fryer AF101 (4 QT)
A meaningful step up from a Teflon basket - the basket and crisper plate are PFAS-free ceramic (sol-gel), not PTFE - but it is still a wear-prone applied coating food scrapes at 400F. For a coating-free food path, a bare convection oven with a steel tray avoids coatings entirely, or see the coating-free glass-basket picks (Fritaire, Willow) in air-fryers.
Instant Pot Vortex Plus 6QT Air Fryer
The stainless steel is the exterior; the basket food-contact surface is a PTFE/PFA/FEP fluoropolymer per Instant's own disclosure. For a coating-free food path, see the coating-free glass-basket picks (Fritaire, Willow) in air-fryers, or air-fry in a convection oven on a stainless tray.
Standard PTFE / Teflon-basket air fryers (most Ninja, Instant, Cosori)
Standard PTFE/Teflon-basket air fryers - the bulk of the Ninja, Instant, and non-ceramic Cosori lineups. A fluoropolymer coating on an aluminum basket, run at 400F+ with food tumbling against and scraping it every use, is the single worst version of the coating problem and disqualifying for a plastic-free rating. The honest alternative is any of the picks above, or simply air-frying in a convection/toaster oven on a stainless tray.
Common questions about air fryers
Is there a fully plastic-free option for air fryers?
No. None of the 7 air fryers we recommend is fully plastic-free. The closest is the Nuwave Combi Steam Oven, which we rate as no-contact plastic: contains plastic (housing, handle, exterior) but none of it is in the contact path — it never touches your food, drink, or skin.
Which air fryers do you recommend most?
Of the 7 air fryers we recommend, Nuwave Combi Steam Oven takes Best Metal-Interior Oven, COSORI TurboBlaze Air Fryer takes Best Conventional Basket and Our Place Wonder Oven takes Best Overall (Oven Route).
Which air fryers should you avoid?
Among the air fryers we have reviewed, we do not recommend WILLOW Eco Series Glass Air Fryer, Boswell Glass Air Fryer 7.5QT, Fritaire Non-Toxic Glass Air Fryer, Ninja Air Fryer AF101 (4 QT) and Instant Pot Vortex Plus 6QT Air Fryer. We also suggest skipping Standard PTFE / Teflon-basket air fryers (most Ninja, Instant, Cosori).
