North CFR 1 Dust Mask nicely fills the gap between flimsy disposable dust masks and more serious respiratory protection like the Dustfoe 88. Replaceable filters (NIOSH rating N95) offer excellent dust protection. The low-profile mask body is made of very soft rubber, and is held in place with a double elastic strap. An exhalation valve vents the warm, moist air you exhale downward—helping the filter medium last longer and leaving safety glasses unfogged. All masks are size medium.
