Original Note:
There's never a naked virus floating around. Viruses attach to water droplets or aerosols generated by breathing, talking, coughing, etc. These consist of water, mucus protein and other biological material and are all larger than 1 micron. The N95 filter is around 0.3 micron https://www.usatoday.com/story/news/factcheck/2020/06/11/fact-check-n-95-filters-not-too-large-stop-covid-19-particles/5343537002/
