As COVID-19 restrictions ease nationwide and occupancy levels begin to rise, investing in a high-efficiency particulate air (HEPA) purifier might be beneficial.

According to News-Medical, several published studies evaluating aerosols and submicron particles similar in size to the SARS-CoV-2 virion have shown that portable HEPA purifiers can significantly reduce airborne COVID-19 particles.

Ahmad Sedaghat, a University of Cincinnati College of Medicine researcher, identified the medical literature showing published studies on the effectiveness of HEPA purifiers. Air purifiers could benefit hospitals and physician offices where aerosol-generating procedures occur, but they are also useful for reducing COVID-19 transmission anywhere that large groups of individuals congregate.
