Air fryers and convection ovens both use hot circulating air to cook food faster than a traditional oven. The difference is size, speed, and how you cook day to day.
Air fryer strengths
Compact, preheats quickly, ideal for 1–4 servings. Great for frozen snacks, wings, fries, and reheating leftovers with a crisp finish.
Convection oven strengths
Larger capacity for sheet-pan dinners, roasts, and baking. Better if you cook for a family or want one appliance to replace a full oven for most meals.
Bottom line
Choose an air fryer for quick solo or couple meals. Choose convection if you batch cook, bake, or need full-meal capacity.
