Exactly!why do all the vaping supply company have masks and the general public does not?
It sure is!That’s a good question!
My two dear neighbor Ladies (upper 80's and early 90's) surprised me with these a few weeks ago. Complete with metal strips for the nose and all. How sweet!

I use them all the time when I have to go out and about. And they get very thoroughly cleaned when I get home, big time!
