The main differences between an air fryer and a deep fryer lie in their cooking methods, health implications, taste and texture of the food, versatility, and ease of use and cleaning. Here's a detailed comparison:

1. Cooking Method
Air Fryer: Uses rapid air technology to circulate hot air around the food. This cooking method mimics the results of frying with little to no oil. More suitable for home use。
Deep Fryer: Cooks food by immersing it completely in hot oil. The oil conducts heat and cooks the food quickly, creating a crispy outer layer. Large oil capacity, high efficiency, fast recovery times, advanced burner design, built-in filtration system. It's more suitable for restaurant, fast food restaurant, snack bar. 

2. Health Implications
Air Fryer: Generally considered healthier because it uses significantly less oil, reducing the fat and calorie content of the food.
Deep Fryer: Although foods cooked in a deep fryer absorb more oil, but make the food more crisp outside juicy more delicious, than the air fryer for a wider range of applications. 

3. Taste and Texture
Air Fryer: Can achieve a crispy texture, but some people find the results less similar to traditional frying. The texture might be closer to oven-baked rather than deep-fried.
Deep Fryer: Produces a classic, deep-fried taste and a very crispy, crunchy texture that many people prefer for fried foods.

4. Versatility
Air Fryer: More versatile in terms of cooking different types of food. It can bake, grill, roast, and even dehydrate in addition to air frying.
Deep Fryer: Primarily designed for frying, and while it excels at this, it has limited versatility compared to an air fryer.

Air Fryer: Often easier to use and clean. Many parts are dishwasher-safe, and there’s less mess since there’s minimal oil usage.
Deep Fryer: Cleaning can be more cumbersome due to the large amount of oil used. The oil needs to be filtered or disposed of after cooking, and the fryer itself can be messier to clean.

6. Cooking Speed
Air Fryer: Generally cooks food faster than an oven but may take slightly longer than a deep fryer for some items due to the lack of direct oil immersion.
Deep Fryer: Cooks food very quickly because the food is submerged in hot oil, providing direct and even heat.

7. Safety
Air Fryer: Generally considered safer to use as it involves less hot oil, reducing the risk of burns or fires.
Deep Fryer: Requires careful handling due to the large quantity of hot oil, which can pose a risk of burns or fire if not used properly.
