Wearing a N95 or KN95 would save 40,000 lives a year if everyone wore them. Masks are
required for the same reason you can not drive 85 MPH in a school zone. The more you wear the
masks the less of a problem it is. N95 masks stop 95% or more of viruses, smoke and other particulates.
They stop viruses down to .007 microns plus almost everything else.
