A long-selling, quiet 4 qt Ninja that Serious Eats and Food Network like, but it's small for families, and Wirecutter dismissed it for running hot and a tray that can fall out.

Common Ninja AF101 4 Qt problems

  • Small 4 qt basket

    Serious Eats says the basket may be too small for a family, Wirecutter says it fits less food than its picks, and some Amazon owners say the basket is too small for their needs.

  • Runs hot; tray can fall out

    Wirecutter says the removable tray liner falls out when you turn food out of the basket, a burn risk, and that the machine runs too hot.

What experts say

  • Serious Eats: Another great air fryer: one of the few small models that kept up with larger ones, fairly silent; buttons are tedious and the basket is small for families.
  • Food Network: Best mid-size pick ('Ninja 4-Quart Air Fryer'): sturdy, with a dehydrate function; not ideal for large households.
  • Wirecutter (NYT): Dismissed: the tray liner falls out when emptying the basket, it runs too hot and fits less food than the picks.
