The threads of an N95 mask would create a gap ~27ft in diameter between them.

So this time, fouci was right, masks don't do anything.

Way back when this covid thing began, I swore they were saying that an N95 mask had a pore size of around 300um (microns) and that covid's virus was a little under that. What I read in trying to verify your post was completely different compared to a year ago. They were talking in nm (nanometers). I'm seriously confused and wondering if I wandered into another reality. I don't mind, I just wish it was a reality that didn't include anything related to covid.
