A Dust Mask That Actually Works
By Michael the Builder from Western North Carolina on June 19, 2010
These are great masks. I do residential remodeling, and often deal with plaster/drywall dust, sawdust, fiberglass, etc. The masks are durable and I get several usages out of one before tossing it. I have a beard that I keep trimmed short (about 1/4") and the masks seal great over it. I buy 2 cases at a time and keep them in the truck.
