Price: Many people argue that cloth masks can’t be effective because they can’t filter out viral particles, which are extremely tiny. But, as Larry explained, most of these particles leave the mouth and nose in much larger droplets that become smaller through evaporation as they move away from the body. Trapping droplets with the mask means not nearly as many viral particles escape. So, when all parties in a gathering are wearing well-constructed, well-fitting masks, it provides an extra layer of safety for everyone. If two people are wearing masks, the viral particles can travel about 5 feet away from each individual. When an infected person is not wearing a mask, those particles can floatthrough the air 30 feet or more and stay alive for up to 30 hours.

It is pointless to try.
