How to Use Your N95 Respirator

Your N95 must form a seal to your face to work properly. Your breath must pass through the N95 and not around its edges. Jewelry, glasses, and facial hair can cause gaps between your face and the edge of the mask. The N95 works better if you are clean shaven. Gaps can also occur if your N95 is too big, too small, or it was not put on correctly.
