I'm not saying the linked article is wrong, in fact a very cogent and intelligent argument was presented to explain just why farts get through .... clothing (being a gas which is molecular) and a virus, being amazingly BIGGER, could be stopped by a mask.
That is the main reason why I posted it. If a mask blocked a fart smell, you also wouldn't be able to get oxygen to breath.
I still believe that wearing a cloth mask or even a N95 offers very little protection you from catching the virus, but I do think it helps in keeping a person who is contagious from spreading it to others if they wear the mask properly. So to me wearing a mask, does help with controlling the spread, since many folks are tending to have minor symptoms and it is also cold and flu season. I still don't want to see a government mask mandate, unless it only pertains to government property.
Because of the nature of my job and the amount distance I travel everyday, I get tested regularly. What I have observed is that the people giving the drive up tests are wearing a mask, face shield, gowns, booties and frequently change their gloves. When I have had to go inside, the people giving the tests are also wearing some sort of positive pressure helmet and face shield.
