KN95 Disposable Protective Face Mask（Head-strap Type）
1.Take out the mask from the packaging. Unfold the mask and place mask against face with the nose clip across the bridge of nose, and the bottom under the chin. Hold the mask on the face with one hand. With the other hand pull the bottom securely under the chin.
2.Pull the top strap over your head resting it high at the top back of your head. Pull the bottom strap over your head and position it around the neck below the ears.
3.Adjust the mask for a comfortable fit as necessary. Make certain hair, facial hair and clothing are not between your face and the mask as they will interfere with fit. Make certain mask is completely opened and edges lay flat against the face.
4.Perform a User Seal Check. To check the mask-to-face seal, place both hands completely over the mask and exhale. Be careful not to disturb the position of the mask. If air leaks around the nose, re-adjust the nose clip. If air leaks around mask edges, adjust position of strap and make certain mask edges fit snugly against the face. If you CANNOT achieve a proper seal, DO NOT enter the contaminated area.
