Most non-idiots (or non red hats) figured out two years ago that most non n95 masks don't filter out virus of a certain size. They also figured out virus travel in microdroplets which do get trapped by some masks, and that the biggest impact is in disrupting airflow during exhalation/inhalation. Hence why the preferred gater worn by redhats does fuck all.
I put someone on ignore, but then follow their threads!
No wait, sorry...that's you.
