I have a box of masks which I bought around 20 years ago. I originally got them for when I mow the lawn but just quit mowing when it is dry.
A couple of weeks ago I got the box out and read the directions. They basically said they were not good for anything. At least they qualify as masks,
Yep. I have a pack of masks from several years ago that were for residential use, to block paint fumes, sawdust, all that. I could slap one on and go anywhere, and they aren’t worth a warm bucket of spit.
