According to the Environmental Protection Agency (EPA):
When used properly, air cleaners and HVAC filters can help reduce airborne contaminants, including viruses in a building or small space. By itself, air cleaning or filtration is not enough to protect people from exposure to the virus that causes COVID-19. ( Air Cleaners, HVAC Filters, and Coronavirus [COVID-19])
However, air filtration, in conjunction with other best practices recommended by the Centers for Disease Control and Prevention (CDC), can help reduce the potential transmission of COVID-19. To read the CDC’s recommendations for employers to reduce virus transmission, visit https://www.cdc.gov/coronavirus/2019-ncov/community/guidance-business-response.html.
Portable air cleaners are designed to draw in air and move it through a filter before returning the now clean air to the room. To reduce virus transmission, the purifier needs to be capable of removing particles less than 1 µm. Air cleaners are rated by how much air they can filter, their clean air delivery rate (CADR) per square footage in an hour. For instance, an air cleaner listed for a 500 sq ft. room might exchange the air in that space five times in an hour, but if placed in a larger area will only exchange the air three times, making it less effective. Five or six air changes in an hour are recommended to reduce virus transmission. Visit https://schools.forhealth.org/ventilation-guide for a ventilation rate assessment guide to help you determine the size of purifier needed for your space.
When used as part of an overall plan to improve air quality, air purifiers can help reduce the transmission of the virus that causes COVID-19, especially in poorly ventilated spaces. To be effective, air purifiers should have a HEPA filter rated to remove particles less than 1 µm and exchange the air in the area five or six times per hour. For more information, contact
