N95 mask is designed to stop 95% of the particles 0.3 microns in size - that is 300um (nanometers) the average size "virus" size ranges from 70-140um. So the pore size on the surgical grade masks are at least twice as big as the "virus" - only through bridging can the N95 mask have any effect and that is after many particles get past it. Bacterial Meningitis killed the majority of people in 1918 - from wearing face diapers.......time to drop the masks and be sheep no more.
