Could Air Fryers Be Secretly Harming Our Drains? The Hidden Impact on Blocked Drains and Fatbergs

How Air Fryers Can Lead to Blocked Drains and Fatbergs

In the last five years, the humble air fryer has become a kitchen sensation. Lauded for its ability to crisp up food using little to no oil, it’s earned a reputation as the healthier, quicker alternative to oven cooking. Sales have skyrocketed, with millions of households across the UK now proudly displaying an air fryer on their countertop.

But while this gadget has transformed the way we cook, it may also be quietly contributing to a less welcome transformation, the rise of blocked drains, kitchen sink blockages, and even fatbergs. Knowing how to clean an air fryer properly can help reduce the grease and oils entering your drains.

Air Fryers: Cleaner Eating, Messier Cleaning, Leading to Blocked Drains?

Before the air fryer revolution, many of us cooked fatty foods in the oven, often laying them on trays lined with foil or baking paper. After cooking, the solidified fats and oils could be wrapped up and thrown straight in the bin. Simple, clean, and importantly kept out of the drainage system.

Fast forward to the air fryer era, and things look a little different. Cooking fatty foods now means greasy baskets and trays that need rinsing and scrubbing after every use. Because these components are cleaned in the sink, often under hot water, the resulting greasy rinse water flows straight down the kitchen sink and into the drain.

Whether we realise it or not, this small change in routine, rinsing instead of scraping, is leading to increased fats, oils, and grease (FOG) entering domestic drainage systems. Multiply this by the millions of air fryers in use across the UK, and it turns out that in our quest for healthier meals, we may be creating another problem: blocked drains and kitchen sink blockages.

The Hidden Cost of Convenience: Fatbergs and Blocked Drains

When fats, oils, and grease are washed down the sink, they don’t simply flow away harmlessly.

  • Unpleasant odours from kitchen sinks or outside drains
  • Slow-draining water or kitchen sink blockage
  • Localised flooding and damage to pipework
  • Massive fatbergs in the public sewer system

 

It’s a case of “out of sight, out of mind” until your kitchen sink starts gurgling or your road ends up flooded.
