The advantages of the air fryer are as follows:

1. The air fryer does not require preheating and has high heating efficiency. If the oven at home is a common size of 30L, the heating machine will take half an hour to heat it, but with the air fryer, you can just put the food in directly. For example, medium-sized chicken wings and crispy pork, a dish can usually be completed in more than ten minutes.

2. The air fryer occupies a small area. If your kitchen is not large, a large oven will take up a lot of space, but an air fryer is usually slightly larger than a rice cooker and is very easy to move.

3. The air fryer can be regarded as a smaller version of the oven, but it is not interchangeable with the oven. It is most suitable for small families with 2-4 members.

4. In terms of taste, the air fryer is suitable for those who prefer fried food on weekdays. The air fryer does not necessarily use no oil at all. The ideal state is to simply brush a layer of oil on the surface of the food to simulate the best fried food effect.
