Which is better: an air fryer or a microwave?

It depends on how you cook. A microwave uses radiation heating to vibrate water molecules, making it the fastest option for reheating liquids, defrosting meats, and steaming vegetables. An air fryer uses convection heat (circulating super-hot air) to give food a crispy, golden texture with minimal oil. For crispy chips, chicken wings, or baking, choose an air fryer. For speed, defrosting, and quick meals, a microwave is essential.
