Glass Air Fryer (Oil-Less)
The large halogen "glass bowl" cooker - food sits on bare stainless racks inside a glass bowl, so the food path is genuinely coating-free, at the cost of a bulky form factor and mixed cooking reviews.
Plastic-free verdict: No-contact plastic
Food cooks in a glass bowl on stainless steel racks, so the entire food-contact path is glass and bare metal with no PTFE, PFOA, or nonstick coating at all. The plastic is in the lid unit that houses the halogen element, fan, and controls, which sits above the food and doesn't touch it. On materials alone it's one of the cleanest options in the category; the caveats are about form and performance, not coatings.

What it's made of
| Part | Material | Food contact |
|---|---|---|
| cooking bowl large tempered glass bowl; glass type not specified by the brand | Soda-Lime Glass | Yes |
| cooking racks food rests directly on the stainless racks | Stainless Steel (304 / 18-8) | Yes |
| lid / heating unit (halogen element, fan, controls) sits on top of the glass bowl; houses the electronics - not in the food path | Plastic (other / unspecified) | No |
A 16-quart halogen/convection "oil-less" cooker - the tall glass bowl with a powered lid, rather than a drawer-style basket. Its plastic-free appeal is real: glass bowl plus bare stainless racks means no coating anywhere near the food, and both are dishwasher safe. The tradeoffs are practical, not chemical: it's big and bulky, the halogen glass-bowl style cooks differently from a basket air fryer, and independent reviews of cooking performance are mixed. Also sold under the Granitestone name. Buy it for the coating-free materials, not because it's the best-performing air fryer.
Pros
- Fully coating-free food path - glass bowl + bare stainless racks
- Large capacity; racks and bowl are dishwasher safe
- No PTFE/PFOA anywhere food touches
Cons
- Bulky halogen glass-bowl form factor, not a compact basket
- Mixed reviews on actual cooking performance
- Glass bowl is heavy and breakable
