Look for a high wattage (around 1700‑1800 W) for fast, even cooking, and a wide temperature range up to 450 °F for crisping. Dual‑basket or dual‑zone designs let you cook two dishes simultaneously, which is a big time‑saver for families. Extra conveniences like preset programs, a viewing window, and dishwasher‑safe parts add value and simplify daily use.

Dual‑basket air fryers, such as the Cosori Dual Air Fryer and Ninja Foodi DualZone, let you cook two different foods at once without mixing flavors, which is ideal for protein and vegetables. Single‑basket models like the Cuisinart or Iceagle often have larger single chambers but require sequential cooking, which can lengthen meal prep time. The trade‑off is usually price and countertop space.

More presets (10‑12 on models like the Iceagle and Cosori) can make it easier to achieve consistent results for specific foods, reducing guesswork. However, if you’re comfortable setting time and temperature manually, a simpler 5‑6 preset model such as the Cuisinart can deliver the same performance at a lower price. Choose based on how much you value convenience versus budget.

Look for dishwasher‑safe baskets and non‑stick or ceramic coated interiors, which are featured on the Cosori TurboBlaze and Chefman TurboFry models, making cleanup quick. Models with a large viewing window, like the Iceagle, may have more seams to wipe down, so consider whether the visual benefit outweighs extra cleaning effort. Regularly empty the crumb tray and wipe the heating elements to keep performance optimal.

Higher wattage (1700‑1800 W) and a max temperature of 450 °F, found on the Cuisinart and Ninja Pro XL, deliver faster air circulation and a crispier exterior, especially for frozen foods. Lower‑watt models may require longer cooking times or pre‑heating, which can affect texture. If you frequently cook large batches or frozen items, prioritize a high‑power unit.

A timer with automatic keep‑warm, like the Cuisinart’s 60‑minute timer, helps keep dishes ready for serving without overcooking, adding convenience for busy households. While not essential for basic frying, it reduces the need for a separate warming dish and can improve overall meal flow. Models without this feature may be cheaper but require more manual monitoring.

TurboFry models, such as the Chefman TurboFry Touch and Chefman Air Fryer TurboFry, use high‑speed DC motors and specialized “Turbo” settings that can cut cooking time by up to 40 % compared to standard convection units. This speed boost is most evident with frozen foods and large batches. If you value quick turnaround, a TurboFry model offers clear performance benefits.

Higher‑priced units often include stainless‑steel interiors, robust dual heating elements, and premium coatings that resist wear, as seen with the Cuisinart and Ninja Pro XL. Budget models may use thinner plastics and fewer safety features, which can affect lifespan. Investing in a well‑built appliance can reduce replacement costs and maintain consistent cooking quality over years.

Touch‑screen interfaces, like those on the Instant Pot VersaZone and Chefman TurboFry, provide clear visual feedback, programmable presets, and easier cleaning of the control panel. Dial controls, found on the Cuisinart, are often more intuitive for quick adjustments and may be more reliable over long term use. Choose based on your preference for modern aesthetics versus straightforward mechanical operation.
