Indoor air quality was a significant concern during the COVID-19 pandemic, especially once scientists discovered that the virus was airborne. However, is it still as much of a priority today?
Most people primarily think of air conditioners as appliances to keep people cool. However, a 2024 study of office air conditioners shows that they promote indoor air quality by minimizing the harmful effects of bushfire smoke.
The research indicated air conditioners used in office environments can trap particles and reduce people’s exposure to harmful elements such as sulfates and nitrates. The researchers collected particulate matter from commercial air conditioner filters during the peak bushfire season in Australia. Evaluations showed the daily particulate matter levels were usually two to three times the average amount. However, some hourly maximums were 10.5 times the usual.
The team took samples for four months, finding the specimens exceeded national air quality standards 19% of the time. Analyses performed in a university showed commercially available air filters captured significant amounts of bushfire smoke, reducing the associated hazards for building occupants.
