That's a lot of words for "masks don't work".

People touch their face obsessively with masks on. Adjusting them, taking them off and back on again, chin strapping, throwing them in a pocket/purse/passenger seat.

If you've got a beard, they're worthless. If you've worn it more than a few hours, they're worthless. If you've taken it off and put it back on, they're worthless. If you've touched the inside face panel, they're worthless.

They're worthless.
