A more useful shortlist
Find an air fryer for your actual cooking routine
Choose a pull-out basket, a powered pod over a glass vessel, or a door-front countertop oven, then decide whether one cooking area or two independently controlled zones are essential. A divided single drawer can make two zones without becoming two baskets; an oven with multiple tray positions still does not provide independent settings. Add capacity, control, temperature or materials requirements only if they are genuinely essential; an unknown specification does not satisfy a must-have. If a stainless-steel basket body matters, distinguish that construction from the nonstick coating applied to it. The advanced questions also separate manufacturer-documented top-and-bottom heating from two independently controlled cooking zones.
