Ninja Air Fryer AF101 (4 QT)
The #1 bestselling basket air fryer. Its basket and crisper plate use a PFAS-free ceramic (sol-gel) nonstick coating - genuinely better than a Teflon basket, but still an applied coating food scrapes at 400F, so it is not coating-free.
The verdict: Minimal plastic contact
The AF101 is the model most people mean when they say "air fryer" - Ninja's 4-quart basket unit and a perennial bestseller. Its saving grace is that the basket and crisper plate are NOT Teflon: Ninja states both are a ceramic (sol-gel) nonstick that is PTFE-free and PFOA-free. That is a real step up from the standard fluoropolymer basket, and worth separating from the Teflon-basket crowd. But "ceramic nonstick" is still an applied coating on an aluminum basket, running at 105-400F with food tumbling against it and being scraped out every use - sol-gel coatings wear and eventually shed. So it lands at minimal-contact: better than PTFE, not coating-free. If you want to avoid a coating entirely, a bare convection/toaster oven with a stainless tray, or one of the glass-basket picks, puts nothing coated under the food.

The 4-quart basket unit most people mean when they say "air fryer" - a perennial bestseller in the familiar pull-out-drawer form factor, cheap, with a dishwasher-safe basket and crisper plate. Treat it as the least-bad coated basket; reach for a bare oven-and-stainless setup or a glass-basket model if you want no coating in the food path at all.

- A real improvement over a Teflon-basket air fryer

- Applied ceramic sol-gel coating on aluminum that food scrapes at 400F and that wears and eventually sheds over time
