Place thumb at center of nosepiece and unfold the respirator by pulling top part (with nosepiece) up and bottom part down so the respirator is open all the way(1). Straps should be held on the top panel.
Bend nosepiece slightly around thumb at center of nosepiece.
Perform a User Seal Check. To check the respirator-to-face seal, place both hands completely over the respirator and exhale (5). Be careful not to disturb the position of the respirator.
If air leaks around the nose, readjust the nosepiece as described in step 4. If air leaks around respirator edges, adjust position of straps and make certain respirator edges fit snugly against the face.
DO NOT utilize the respirator for flu protection if you cannot achieve a proper seal.
