FAQS - RENEWAIRE ERVS AND COVID-19 - RenewAireASHRAE recommends that air filtration be improved to MERV-13 or the highest compatible with the filter rack, and [to] seal edges of the filter (rack) to limit bypass. Only HEPA filters can provide 99%+ capture of the virus particles themselves. But MERV 13 should be able to reduce aerosol transmission because they can capture some of the aerosol particles in the 0.3 to 1.0 micron size range.
