Note: Every time you wear a mask, please check the airtightness of the mask as follows:

1. Positive pressure tightness test

Cover the mask with both hands and exhale vigorously. If the air overflows from the edge of the mask, it is improperly worn. The headband and the metal strip of the bridge of the nose must be adjusted again until there is no air leakage.

2. Negative pressure tightness test

Cover the mask with both hands and inhale vigorously. If the center of the mask sinks, it means it is worn correctly. Otherwise, it needs to be adjusted by 2-4 steps until it is airtight.

Note: If the mask has a breathing valve, apply force to inhale. If air enters from the edge, adjust the mask and repeat steps 2-4 until it is airtight. Before entering the work area.
