Original Note:
Air filter material exploits physics to catch particles of all sizes, incl ones much smaller than the gaps between fibers. Surgical masks are inappropriate for airborne hazards due to gaps at the edges, not the material itself. N95s are very effective when used correctly. https://www.youtube.com/watch?v=eAdanPfQdCA https://www.air-quality-eng.com/air-cleaners/filtration-mechanisms/
