3M™ NIOSH N95 Masks - H PPE Supply
Every 3M respirator mask is rated N95 by NIOSH, an American standard for personal protective equipment that certifies the mask to filter out 95% of all airborne non-sticky particulates. This means that, when properly worn, a 3M N95 mask protects not only the people around the wearer, but also provides significant protection to the user as well.
