Meme error.
N95 masks are 95% effective at blocking particles 2.5 nanometers in diameter, or larger.
Covid-19 is a wee bit smaller than that.
Even N99 masks are only 99% effective against particles 2.5nm and larger.
HEPA13 filters take it to 99.9%, still, only against particles 2.5nm and larger.
Pretty much ALL OF THEM these days tell you right on the box that they
are not effective against Covid-19.
Resist the gaslighting.
