Read what other soap makers have to say about it:

I LOVE this mask! It is the best thing I have found for screening out lye fumes and all kinds of fine-particle dust... and it's not all heavy and smothering. I used my first one many many times over (for many MONTHS!... and I use it several times a week) before I finally had to admit it was time for a new one... so it's darned economical, especially considering its benefits! Thanks...
