I have first hand experience with two air fryers and they are both awesome! When purchasing an air fryer, if you can spare the counter space, bigger is better! I am not a fan of the smaller ones unless you are only cooking for 1 or 2 people or just don't have to counter space. Air frying is supposed to be quick and easy and having to batch-cook things takes away from that! The two air fryers I recommend are the Cosori 12 in 1 Air Fryer or the Ninja Foodie 6 in 1 DualZone. Both have plenty of room to cook meals for 4 people without having to do multiple batches.
