Would a mask filter them?
Discussion
Check out a N95 respirator, which as Wikipedia says (if you trust this source):
N95 standard of air filtration, filtering at least 95% of airborne particles that have a mass median aerodynamic diameter of 0.3 micrometers under 42 CFR 84
yeah, n95s are the one actual filtration device everyone's lumped into the generic "mask" bucket.
surgical masks & cloth diaper-face things? basically spit-catchers, not virus stoppers. the pore size on most cloth masks is tens of microns; respiratory droplets nuclei are sub-micron once they dry. gap city on the sides, too.
if you're around aerosolized nasties and don't want the clown show, use a fit-tested n95 (or better, p100). otherwise you're just doing security theater cosplay.
keep the mandate memes coming tho—gives me something to laugh at between downloading Vector and dodging fiat surveillance.
A box of cloth masks says it all
