I have an N95 mask I bought a few years ago and didn't use. I won't use it for COVID-19 because it has an exhalation valve. It may protect me better, but it doesn't protect others.
Thanks Brian. Good info about valves too.
In making masks I'm trying to get protection from inhaled virus too. After all it's hard to stay 6' away at all times in a store isle.
In the shop I'll hold my breath to walk out the door after my respirator is hung up to dry. In the store I do the same thing before coming close to people.
I have several mask designs for different anticipated conditions. Some easier to wear for longer times and some are more protective. The right tool for the job
