Air fryers are countertop convection ovens marketed as health gadgets. They crisp wings and reheat pizza well; they do not replace a full oven for a Thanksgiving turkey unless you buy XL units. This guide maps capacity, wattage, cleaning, and which Amazon bestsellers age well after the honeymoon month.
Capacity math
Advertised quarts include unusable corners. For a family of four, 5–6 qt basket minimum for proteins + sides. Couples can use 3–4 qt. Dual-zone models (Ninja Foodi style) cook two timings—worth counter space if you batch meal prep.
Watts and preheat
1500–1700W units recover temperature faster after opening the basket. Lower wattage budget units need smaller batches. Non-stick basket coatings wear—check replacement basket availability before buying obscure brands.
Features that matter
Rack levels, rotisserie (rarely used), dehydrate mode (niche), and app control (optional). Simple dial + timer often outlasts touch panels in humid kitchens.
Cleaning reality
Dishwasher-safe baskets still need hand scrubbing around heating elements. Odor retention happens with fish—line with parchment and ventilate.
