Martin Lewis' warning to anyone who uses an air fryer instead of an oven Martin Lewis, the go-to guru for financial tips, has issued a word of caution to those swapping out their ovens for air fryers in a bid to cut costs.
"A microwave is also 1000W so per minute it's the same cost as an oven, but things done in the microwave when you're cooking a one-off, a one off jacket potato for example, is far more efficient because it's 10 minutes in the microwave, it might be an hour and a half in the oven.

When comparing this to traditional ovens, Lewis detailed: "Now an oven is typically 1-2000w so you're paying around 34p or 68p an hour.
