North CFR 1 offering 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.
