Focus on total capacity, the number of independent cooking zones, and temperature range. Look for features like Smart Finish or Sync Finish that let two foods finish together, and check if the baskets are dishwasher‑safe for easy cleanup. Also consider the variety of preset functions (air fry, roast, dehydrate, etc.) that match your cooking style.

The Ninja offers two 4‑quart zones with Smart Finish and Match Cook, ideal for cooking two dishes simultaneously with separate temperature control. Philips provides a larger 9.5‑quart total capacity with a 6‑liter and 3.5‑liter drawer, plus an auto‑sync cooking time feature. If you need more overall volume, Philips wins; for tighter zone control, Ninja is preferable.

A single basket gives you a spacious cooking area and powerful 3600 rpm fan for even crisping, but you cannot cook two different foods at the exact same time without pausing. Dual‑basket models let you prepare a main and a side concurrently, saving time for family meals. Choose a single basket if you rarely need simultaneous cooking; otherwise, the dual‑basket option adds convenience.

Air fryers circulate hot air to achieve a crispy texture with up to 75 % less oil, reducing overall fat and calorie intake. Dual‑basket designs let you cook multiple items with little to no oil while keeping flavors separate, which is harder to manage with a deep fryer. The result is a healthier meal without sacrificing the crunch you love.

Yes, they expand the appliance’s versatility, allowing you to make jerky, warm leftovers, or baked goods without using a separate oven. This can save countertop space and reduce the number of appliances you need. If you enjoy experimenting with recipes, these functions make the air fryer a true multi‑cook solution.

Very important, especially for families that cook frequently. Models such as the Ninja and Chefman feature dishwasher‑safe baskets and removable trays, while the GreenPan offers a PFAS‑free drawer that slides out for quick rinsing. Choosing a unit with simple, non‑stick components reduces maintenance time and keeps the appliance performing well.

The Ninja typically costs more but includes advanced features like IQ Boost power distribution, Smart Finish, and a larger overall capacity. Chefman provides solid dual‑basket functionality and a 9‑quart total volume at a lower price point, but may lack some of the premium controls and build quality. If you value precise cooking algorithms and extra capacity, the Ninja’s higher price can be worthwhile.

Consider the typical number of people you cook for and the size of meals you prepare. For a family of four to six, a 7‑to‑9‑quart drawer (like the GreenPan or Philips) comfortably handles a whole chicken and sides. Larger households or frequent entertaining may benefit from the 10‑quart models (Ninja DoubleStack or Ninja DZ401) that can handle two 5‑lb chickens at once.
