Are HEPA\/EPA filters effective against COVID?<\/h2>\n

A common concern is whether HEPA\/EPA filters can filter viruses like the COVID-19 coronavirus. HEPA\/EPA filters removes particles greater than or equal to 0.3 microns<\/span>, but virus particles are smaller. The coronavirus measures 0.06 to 0.14 microns <\/span>in diameter. Are air purifiers then powerless against viruses?<\/p>\n
