Who is telling you to do that?
I have 3M N95 masks I use in my shop.
There was a shortage of them for a while in the first months of the panic but the supply lines are filled back up.
My employer buys Chinese masks for covid. I don’t wear them.
Masks don’t help anyway, see post 26. I’ve been fit tested for respirators per OSHA standards my whole career. Mask hygiene is horrible, practically no one uses them properly.
Proper use of masks as PPE would be; sterile gloves on, clean mask on, do your thing, take mask off and put in garbage, take gloves off and put in garbage.
Repeat with each mask use.
Here’s a study about how viruses spread through “bring your own bag”. Covid spread that same way with masks. https://www.neha.org/node/60021
