Although they are known for cooking food in a healthier way, air fryers have another previously unknown benefit.
As air fryers They have become a popular kitchen appliance for their efficiency, affordability, and ability to cook healthier meals. Now, a new study from the University of Birmingham reveals another reason to use them: air fryers emit significantly less indoor air pollution.
The study examined five common cooking methods while preparing chicken breast in a controlled environment. The researchers measured the levels of particulate matter (PM) and volatile organic compounds (VOCs)both harmful air pollutants.
Among the methods tested, air frying produced the lowest levels of pollution. The researchers found that air frying emitted just 0.6 micrograms of PM per cubic meter of air and 20 parts per billion of VOCs.
In comparison, pan frying – the most polluting method – emitted 92.9 micrograms of PM and 260 parts per billion VOCs. Even cooking, often considered the least polluting method, released slightly more pollutants than air frying.
Particulate matter consists of microscopic particles that can be inhaled, potentially causing respiratory and cardiovascular problems, explains the . VOCs, in turn, are gases that include chemical substances associated with various health problems.
Exposure to these pollutants is particularly concerning as people spend more than 80% of their time indoors, according to the study.
Indoor air pollution has been linked to a range of health risksfrom respiratory irritations and asthma attacks to more serious conditions such as heart disease, neurodegenerative diseases and an increased risk of cancer.
The researchers emphasized that improving ventilation, such as using exhaust fans or opening windows, can help reduce exposure. However, choosing less polluting cooking methods can also make a significant difference.
Christian Pfrang, lead author of the study recently in the journal Indoor Air, noted that while factors such as the amount of cooking oil and stove temperature can influence pollution levels, air fryers consistently emit less pollution. Pfrang also advised continued ventilation after cooking, as pollutants remain in the air for more than an hour afterwards.
