Although in a convection oven you are able to cook food with very little use of oil, an Air Fryer doesn't require oil at all.  An Air Fryer uses hot air to evenly cook the food and pack it with flavor. Moreover, it prepares delicious crispy snacks in very little time. And when it comes to price, it is lesser than of a convection oven. On the flip side, an Air Fryer is limited to cooking a small amount of food because of its compact size.

A convection oven has an in-built fan that helps circulate the hot air over the food allowing you to cook any food item. It is usually fast, but as compared to an Air Fryer, it requires more time to prepare any given food. But like an Air Fryer, it can also make yummy snacks.  A convection oven, due to its size and capacity, is better-suited to roast large batches of meat and vegetables.

There is no comparison for the original deep-fried food when it comes to taste and flavor, but one has to think about health as well. Deep fryers require the food to be completely submerged in the oil so that the oil can fry it evenly, providing a crispy finish. Food prepared in the deep fryer has a thicker crispier crust. One of the main features of deep fryers is that it drains out the excess oil harmful for our body. When it comes to Air Fryers, these machines use hot air circulation to cook the food instead of oil. Even though there is an option of brushing your food with little oil, many people prefer without it.  Air fryers are much easier to clean as well because of the low oil usage. However, sometimes food may come out dry as compared to a deep fryer. 

Air Fryers are a healthier option than a regular deep-oil fryer. You can cook many tasty and sumptuous recipes, like restaurant-ordered french fries with an Air Fryer. By using less oil, you're likely to cut a ton of calories, fat, and harmful compounds found in the regular fried foods.  Although an Air Fryer uses less or no oil, the majority of food prepared in the Air Fryer is high in fat and calorie count. The intention of creating this machine is to offer you fried foods that are restaurant quality but, without or little oil. Therefore, to answer this question, yes Air Fryers are healthy, but only to an extent.

Brand Name 

Bigger companies like Cosori Ninja or Cuisinart put a lot of effort into their R&D to make their appliances safe and user-friendly. Also, the branded machines come with an extended warranty. Therefore, when investing in appliances, go for brands.

Wattage
