corona is not a gas attack
masks aren't for "filtering" air, they're literally to prevent you from touching your face and getting the virus particles on your skin. You can use surgical masks but you still need to cover eyes, DONT TOUCH it, dispose of it after taking it off. DON'T use scarves, "harajuku" masks, take them off half way to have them on your chin.
Wash your hands too.
Idiots who don't understand this are the reason goverments are against using masks altogether.
