According to 3M, which says it is the largest manufacturer of N95 respirators in the United States, their masks can be reused as long as it “still forms a good seal to the face and is not dirty, damaged, or difficult to breathe through.” The company said to store the masks in a “breathable paper bag,” and to wash your hands between uses.
