Keith S,

I found one new 3M Cool Flow N95 Pro 8511 respirator in my tool box. I tried to give it to my son but he wouldn't take it. So we agreed that whoever takes it should be the only one who goes out to the store.

My question is, how reusable is it? I know we can't share.

Your thoughts please. I started to send this to you in a message but I thought your answer might be helpful to others.
