New research by the University of Birmingham suggests that air fryers can help improve indoor air quality compared with traditional deep-fat frying, as they emit far fewer volatile organic compounds and other airborne particles during cooking. However, the study, published in the American Chemical Society journal ES&T Air on January 28, warns that keeping the appliance clean is essential, as residue buildup increases emissions over time.
Proper kitchen ventilation can further help disperse pollutants, making air frying a cleaner cooking option overall.
Beyond the science, the air fryer’s rise has been driven by changing cooking habits. Introduced in 2010, the appliance surged in popularity during 2020 as people sought healthier, faster ways to cook. Since then, its sleek design and speed have made it a kitchen staple. But does it sacrifice flavor, or deliver a time- and energy-efficient way to eat more vegetables?
