Thank you greymouser7, all that stuff "Can" work but I believe the masks (blue ones) definitely are the biggest joke of the equation. They're no way near a n95 which isn't good enough to stop a virus. Virus particles are smaller than the scent of a fart which can be smelled ( lol actually tasted) easily through an n95 mask, in my opinion would be a bare minimum. Funny thing is they all disappeared off the shelves and I hardly seen anyone wearing them, something to think about.
