Original Note:
Viruses don't float in the air on their own, they're attached to tiny water droplets called aerosols (from coughing and breathing). These are ~1µm in size. A good N95 mask is designed for particles between 0.1 and 0.3µm, so masks are very effective at capturing airborne viruses https://www.usatoday.com/story/news/factcheck/2020/06/11/fact-check-n-95-filters-not-too-large-stop-covid-19-particles/5343537002/
