@conbo61 nails this here ......... I concur.
That being said, please go to this forum, upper right corner and search for "mask recommendation" ...it comes up with 237 posts. Not all of them are exactly what you're looking for, but there's enough info here for you to read about masks for days and days!
I did the search here, and I copied the link for you, I hope it works. If it doesn't work, let me know ....
PLEASE .... DON'T
