Good article at university of Mn that explains the efficacy of different type masks. Google it. I’m too lazy to link it.
No- I don’t think a cotton mask offers you any protection. For gawd sakes ticks crawl through cotton. Virus can’t even be seen with a light microscope- it takes an electron microscope to see one. 2000 fit on a single pollen grain.
N95 - some protection there.
