Air fryer owners are destroying their heating elements with foil

We all love a good kitchen hack, especially when it saves us from the dreaded washing up. For thousands of British households, the ultimate shortcut has been lining their beloved air fryer with aluminium foil. It catches the grease, keeps the basket spotless, and seems perfectly safe. But appliance experts are now issuing a stark warning: this common trick is quietly destroying your air fryer’s heating element.

The hidden danger of tin foil

Air fryers work their magic by circulating super-heated air around your food at high speeds. This rapid airflow is what gives your chips that perfect crunch. However, when you cover the bottom of the basket with a solid sheet of tin foil, you completely block the meticulously designed vents.

• Air fryer owners are destroying their heating elements with foil
• Storing olive oil next to the cooker destroys its antioxidants
• Pruning tomato plants from the bottom reduces your summer yield
• Washing microfibre cloths with fabric softener ruins their cleaning properties
• Retinol users over 50 are accelerating skin ageing before bedtime

With the airflow restricted, the hot air has nowhere to go. The heat bounces back up towards the heating element at the top of the machine. Over time, this intense, trapped heat forces the element to work overtime, causing it to overheat and, eventually, burn out completely. What started as a clever way to save five minutes at the sink could end up costing you the price of a brand new machine.

What you should use instead

Does this mean you have to go back to scrubbing baked-on grease? Not at all. The secret is maintaining that crucial airflow whilst still protecting your basket.

Instead of kitchen foil, experts highly recommend using specially designed perforated parchment paper liners. These clever liners feature pre-cut holes that align with your air fryer’s vents, allowing the hot air to circulate freely whilst catching the worst of the crumbs and grease. If you do find yourself in a pinch and absolutely must use foil, ensure you only wrap the food itself loosely, rather than covering the entire base of the basket.

Stop sacrificing your expensive appliances for the sake of an easy clean-up. Ditch the foil today and keep your air fryer crispy, safe, and fully functional for years to come.
