There are significant differences that mainly concern energy efficiency and structure. The convection oven, especially the built-in one, has a much larger cooking chamber and this implies a greater energy consumption to reach and maintain temperatures. In addition to the different consumptions, this difference translates into different times It is important to remember that there are also differences related to the versatility of the two products. With the air fryer, in addition to frying without oil, it is often possible to carry out other types of cooking such as grilling, roasting or cooking while whipping, while the oven in most cases only performs its classic function.
