Nuwave
Nuwave's older induction and small-appliance range is conventional, but its Bravo and Combi Steam ovens are notable for a genuinely uncoated stainless interior with stainless racks and trays - the company states the Combi Steam Oven is PFAS-free, aluminum-free, and pairs a stainless air-fry tray with a borosilicate glass casserole. That makes the oven-style units a real coating-free route to air frying. Housing and controls are plastic but outside the cavity, as on any oven.
