High effectiveness of mobile air purifiers and masks
Study on the effectiveness of reducing indoor aerosols by using air purifiers. A simulated session with 4 participants and simulated exhaled SARS-CoV-2 aerosols on July 7, 2021, U.S. Department of Health, CDC.gov
What is already known about this topic?
Air purifiers should be supplemented with mobile high-efficiency particulate air purifiers (HEPA) to reduce the number of infectious particles in the air.
What does the study find out?
A simulated infected meeting participant exhaling aerosols was placed in a room with two simulated uninfected participants and one simulated uninfected speaker. Using two HEPA air purifiers close to the aerosol source reduced the aerosol exposure of the uninfected participants and speakers by up to 65%. A combination of HEPA air purifiers and worn surgical mask reduced aerosol exposure by up to 90%.
What are the implications for public health practice?
Mobile HEPA air purifiers can significantly reduce indoor exposure to simulated SARS-CoV-2 aerosols, especially when combined with an additional surgical mask.
