Real-world data show that filters clean COVID-causing virus from air
11 July 2022
- The results suggest that air filters could be used to reduce the risk of patients and medical staff contracting SARS-CoV-2 in hospitals, the study’s authors say
- The study used high-efficiency particulate air (HEPA) filters, which blow air through a fine mesh that catches extremely small particles. The researchers collected air samples from the wards during a week when the air filters were switched on and two weeks when they were turned off
- In the general ward, the team found SARS-CoV-2 particles in the air when the filter was off but not when it was on
