• Facing the face mask without nose clip, pull the ear band with both hands to make the nose clip above the mask.
• Please the lower side of the mask under the chin so that the nose clip is located on the bridge of the nose, place the mask over the face.
• Pull the ear band behind the ear and adjust the position until comfortable.
• Place the fingers of both hands in the middle of the metal nose clip and press in and move the fingertips along the clip to the sides until the clip is pressed close to the bridge of the nose. Using only one hand to hold the nose clip may affect the tightness of the mask. 
• After wearing, the user must check the tightness of the mask to the face.

1. For rapid breathing, if air leaks from the bridge of the nose, read just the nose clip as per step 4, if air leaks from the edge of the mask, readjust the ear band; if a good seal cannot be obtained, repeat steps 1-4.
2. If there is no air leakage, wear it successfully.
