cloth masks don't work that way. Besides
that wasn't the point. The mask isn't stopping your breath which is what the virus is riding on.
I worked in a hospital for 30 years. An example I was a biomed so if I was called to solve a problem in the ICU I had to wear a jumpsuit, gloves, mask, booties, and a head covering. When I left the room I disposed of them even though I was going into the room next door and had to suit up again! Believe me a pain in the ass. Going into surgery was even worse. How often do you wash your cloth mask or change the disposable?
