Of course masks help.. We always knew that. The main problem was hoarders.. which lead to medical professionals not having enough masks in supply.
3M Should be ashamed of themselves for not selling every single mask they make to Americans in America. Then we have CHINA sending us infected and defective supplies. Bizzaro World!
TP; yes.
Flour? Maybe.
MAsks? Uh; no!
Unless you were going to scalp them.
One mask is all ANYONE needs (if they are NOT interfacing with a lot of other folks).
