Focus on the cooking technology (airflow design, temperature range), control type (touchscreen vs. knob), and extra functions like bake, roast, or dehydrate. Space‑saving dimensions and basket shape matter if you have limited countertop room. Finally, check for safety features such as shake alerts or automatic shut‑off.

Touch‑screen units, like the Chefman TurboFry, let you set precise time and temperature and often include visual cues and alerts. Knob‑controlled models, such as the Bella 5‑in‑1, are simpler to operate and may be more intuitive for users who prefer tactile feedback. Both types can deliver similar cooking results, but digital displays usually add programmable presets.

The Instant Pot Vortex 2QT stands out because it combines four cooking functions (air‑fry, bake, roast, reheat) with EvenCrisp technology and a dishwasher‑safe basket at a competitive price point. The Chefman models offer solid performance and space‑saving design, but they lack the multi‑function versatility of the Vortex. For most households, the Vortex provides the most features per dollar.

Both reach up to 400 °F, but the Vortex uses top‑down airflow (EvenCrisp) that can produce a more uniform golden crust, especially on frozen foods. Chefman's TurboFry includes a shake‑notification that helps achieve crispness by prompting you to toss the food halfway through. In practice, the Vortex may finish slightly faster, while Chefman offers a helpful reminder for even cooking.

Shake alerts can improve texture by ensuring food is moved for even exposure to hot air, which is useful for items like chicken wings or fries. If you frequently forget to stir mid‑cook, the feature adds convenience and may reduce the need for manual checking. However, most users can achieve similar results by manually shaking the basket, so it’s a nice‑to‑have rather than essential.

Most 2‑quart models, including the Instant Pot Vortex, Bella 5‑in‑1, and Black+Decker Purifry, offer dedicated bake, roast, and even dehydrate functions, expanding their use beyond traditional frying. The Chefman units also list bake and roast modes, though they focus more on quick fry‑type cooking. This versatility lets you prepare everything from cookies to roasted vegetables in the same compact appliance.

All listed air fryers feature non‑stick baskets that are dishwasher‑safe, making post‑meal cleanup straightforward. The Bella and Bear models highlight removable trays and dishwasher‑friendly parts, while the Vortex and Black+Decker emphasize easy‑slide‑off baskets. Overall, you can expect minimal hand‑washing effort regardless of the brand.
