[quote]Masks are stupid. They don't even do that much. I mean, yes, they help, but they don't make a huge difference. Plus, breathing your own air is bad for you. It's toxic, and can kill your brain cells. You're supposed to breathe different air, not your own air!! Please don't start a war in the comments. I can have my opinion. Goodnight! So far, not so great. Dammit people![/quote] The mask mostly work if enough people are wearing them. They help prevent you from spreading but are ok at the other way around. Most people don't store mask correctly and I don't either. I try to but mask aren't magical. The carbon thing isn't that big of an issue. Its just something your body need to get used to. I used to get headaches when I wore my mask. But you get used to it and you don't notice. Front line workers go hours with mask on.

Viruses are larger than air particles. The air particles pass through the mask fine

It keeps your spit from flying all over everything. It really has nothing to do with the air. And if everyone wore theirs, this pandemic would most likely already be over.
