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

A common concern is whether HEPA filters can filter viruses like the COVID-19 coronavirus. HEPA 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

Actually, HEPA filters work great <\/b><\/span>at capturing viruses. This is because a HEPA filter works not like a net, but through a process called diffusion<\/b><\/span>. Learn more about how this works here<\/a>.<\/p>\n<\/div>\n<\/div>\n

\n

How often should I change my QT3 HEPA filter?<\/strong><\/h2>\n

We recommend changing the filter after 450 hours of use. The QT3 has a built-in feature to remind you when to change the HEPA filter.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Can I wash a dirty HEPA filter?<\/strong><\/h2>\n

Unfortunately not.<\/b> We ran experiments to test this and found that washing HEPA filters does not prolong their lifespan<\/a>. In fact, washing HEPA filters with water actually decreases<\/b> performance. That\u2019s why we recommend you replace your QT3 HEPA filter after the maximum hours of use.<\/p>\n<\/div>\n<\/div>\n
