Yes, trying to fix

That's the end man

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 https://en.wikipedia.org/wiki/N95_respirator.

droplets >5µm drop within 6 ft, aerosols <5µm float for hours. cloth & surgical masks leak 40-90 % around edges, stop mostly the big drops you can see, not the tiny ones that actually carry viral load. if someone’s sick the smart move is stay home or use a fit N95, not virtue-signal with a leaky...

Would a mask filter them?

but that's not even a little funny
