Verdict: if you already have a convection oven, you probably do not need an air fryer. An air fryer is a small convection oven with a more concentrated fan. The cooking method is the same. The box is smaller.

Pick an air fryer if

  • You cook for one or two people most nights.
  • You mostly reheat, crisp frozen food or cook small cuts.
  • Your oven is slow, old or has no fan.
  • You want a short wait between "hungry" and "eating".

Pick a convection oven if

  • You cook for three or more people.
  • You bake, roast whole birds or cook on two trays at once.
  • You already have a fan setting on your oven and have never used it.
  • You do not want another appliance on the counter.

The difference that matters

Batch size. Air fryers do small batches well and large ones badly. Overfilled baskets steam instead of crisp, because the air cannot move. Count how many portions you cook on a normal night. Two or fewer favors the air fryer. Four or more favors the oven.

Check your oven first

Look for a fan or "convection" symbol on the dial. Many ovens have one that sits unused. Try it with a tray of fries or wings on a rack before you buy anything. If that gives you what you want, the question is closed. The method we use for every comparison starts with the same step: define the job.

Energy use varies by model and by how often you cook. Check the maker's rating and the ENERGY STAR site if you want a figure for a particular product.
