I am pretty convinced this saved me from a COVID infection.
I was stuck in a meeting with a bunch of knuckleheads in a small conference room for 4 hours, none of which were wearing any mask. I wore mine Polygiene mask the whole time.
A number of people ended up infected out of this meeting, including one near me. I did not.
