No, the Ninja Foodi and an Air Fryer aren't quite the same. The Ninja Foodi is a pressure cooker AND an air fryer, while an air fryer is just... well, an air fryer. The Ninja foodi can boil and cook food under pressure.  It also roasts, grills, steams, bakes, and dehydrates ingredients. An air fryer fries food by circulating hot air, as the name suggests. A Ninja foodi has all the features of the air fryer and then some.
