A Chinese guy was caught without a mask and 3 guys (secret police from the way he was held - execution style) tied him up and forced him to wear a pink bra over his face ...
A mask is mostly a reminder not to touch your face and will not likely keep COVID9 at bay - you would need a L4 bio suit to be sure
Masks can last varying times - four hours to several days, depending on usage. You will need hundreds of N95s to be adequately supplied for a few months
I know. The average american will need to spend thousands of dollars just on one person. Can’t imagine a whole family.
Hey bras are about the right shape. You could make two masks out of one bra. They come in different sizes and colors too.
Every shop I worked at that supplied spray painting masks would buy the large size and they didn’t fit me at all. Big gaps so I bought my own. Same thing with gloves. I wear medium but the shops and hell, have the stores only have large. Dangerous to have loose fitting safety gear. I used safety harnesses when going up in the air and yup, all made for fat guys.
