1. Place the mask in the palm of your hand and position the nose clip towards the fingertips to allow the headband to sag naturally.
2. Put on a mask with the nose clip facing upwards and close to the face.
3. Use both hands to pull the headband over the top of the head. The upper headband is placed above the ears of the head and the lower headband is placed below the ears on the neck.
4. Press the fingertips along the nose clip slowly from the middle to both sides until it is close to the bridge of the nose.
5. Cover the mask with both hands and try positive and negative pressure test.
Positive pressure test: cover the mask with both hands and exhale deeply. If the air overflows from the edge of the mask it means the mask is worn improperly. The headband and nose clip must be adjusted.
Negative pressure test: cover the mask with both hands and inhale deeply. The center of the mask will be sunken. If air enters from the edge of the mask it means the mask is worn improperly. The headband and nose clip must be adjusted.
