I test a lot of the best air fryers, and I like to think I have a close connection with the distinguished kitchen appliance. I know what to look for when I'm reviewing them: even cooking, straightforward cleaning, fast heating time, and reliability.

But even if an air fryer ticks all those boxes, there's still one major factor that is, arguably, the most important of all. Price.
