Clean Air Fryer = Cleaner Air Indoors

Summary
- Air fryers produce fewer pollution particles than other frying methods.
- A dirty air fryer can negate its air quality benefits.
- Regular cleaning of air fryers is crucial for optimal results.

Cooking with an air fryer, even for fatty foods, generates fewer air pollution particles than conventional frying methods, according to a University of Birmingham study. Researchers analyzed 12 popular foods, including onion rings and sausages, finding that air frying produced substantially less particulate matter (PM) and volatile organic chemicals (VOCs) compared to deep or shallow frying.
However, the study highlights a critical factor: the cleanliness of the air fryer. Repeated use without thorough cleaning can negate the air quality advantages. Tests showed an air fryer used over 70 times emitted significantly more VOCs and PM particles than a clean appliance. This underscores the importance of regular maintenance and proper ventilation.
The findings suggest that air fryers can be a more environmentally friendly kitchen option. By ensuring regular cleaning and adequate ventilation, the reduction in cooking emissions makes them a viable alternative for domestic settings where indoor air quality is a growing concern.
