Lol, uh, you're right, since it doesn't offer 100% protection it isn't worth
wearing. My N95 respirator mask only offers 95% protection from aerosolized particles to .3 microns. And since the SARS-cov-2 virus can be airborne in droplets down to a micron in size, it's just not worth wearing. Lol. But my N95 is years old (they won't take it as a donation) so its especially not helpful.
And since keeping a 6 ft. social distancing isn't 100% either, uh, it's not great either. So lets not bother. Lol.
