You know a mask is useless because the virus is so much smaller than the gaps in the weave of the fabric, right? Ok, that's not how it works, but I'll let that ride for now. Why else shouldn't I wear a mask? Because they block oxygen and trap harmful carbon dioxide; Ok, ignoring the fact that we PURPOSELY ingest carbon dioxide in fizzy drinks, which is it? Does it let the virus through or does it block oxygen and carbon dioxide? What do you mean which is it, it's both! It can't be both. A small Coronavirus molecule is 60.0 nm. Oxygen and carbon dioxide molecules are 200 times smaller at ~0.3 nm.
