I would offer you a lesson in statistics, but statistically I think that is a low value proposition.
Fortunately I learned how to wear a respirator so I find my N95 shop respirators leave my nose and throat dust free. If I am working with anything nastier, the N100 painting respirator comes out. It's essentially a gas mask with particulate filter.
N95 by the way does not filter virus either. The situation really is
like I said, trying to stop a mosquito with a chain link fence. That a
mask works at all is based on the idea the virus is never just out there
by itself, but is hitching a ride on a droplet. The problem with that
being droplets go down to vapor, goes down to molecules.
Anyone
who has worked in a shop as I have, worn respirators as I have, will
know perfectly well how your nose and throat gets plenty of dust. This
is with filters many orders of magnitude better than the masks we are
being forced to wear.
