But incoming through your mouth doesn’t matter for most infection vectors.How so? Non-oriented fibers filter both directions.
Not only is your mouth generally a hostile environment (better to be bitten by a dog than a human, as I understand!), but your eyes are far better ways to take in whatever is in the air.
The mask over the nose and mouth, with the eyes exposed, is kind of like the “chainmail bra” on the covers of books about warrior maidens . . . uhh, sure, no-one will swing a sword at her exposed belly (and no germs will be so ungentle as to enter through your eyes). Or locking the door to your car, but not wearing a seatbelt . . .
[sidenote: for a downright hysterical discussion/explanation of the magical properties of the chainmail bra, there is a novel called “heroing”, in which it ex matter of factly explained {tongue in cheek, too}.
no. They are designed to keep germs in your breath on the face side, not viruses on the outsideThe masks are intended to protect against droplets (cough. sneeze) which contain the virus.
yes–and the infection is through the eyes (or hand to eyes), not your mouth.but it only takes one infected person to cough or sneeze within 5-6 meters and you risk infection. That has been documented.
