Q: What is the difference between mask and ear style?
A: Head-mounted: 1. Face the side without a nose clip so that the nose clip is located over the mask. Hold the mask on your face with your hand and hold the mask against your chin. 2. Pull the top headband over your head and place it over your head. 3. Pull the lower headband over your head and place it under the back of your neck. 4. Place the fingers of both hands in the center of the metal nose clip and press inwards while moving the fingertips to the sides along the nose clip until the nose clip is fully pressed into the shape of the nose bridge.
Ear-wearing style: 1. Face the side without nose clip, both hands pull one ear strap, the nose clip is located above the mask. 2. Use a mask against the chin. 3. After pulling the ear strap to your ear, adjust the ear strap to feel as comfortable as possible. 4. Place the fingers of both hands on the center of the metal nose clip and press inwards while moving the fingertips along the sides of the nose clip until the nose clip is fully pressed into the shape of the nose bridge.
Before entering the work area, the user must check the mask and face adhesion: 1. Cover the mask with both hands to avoid affecting the position of the mask on the face. 2. If the mask does not have a breathing valve, exhale quickly; if the mask has a breathing valve, inhale quickly. 3. If air leaks from the nose bridge, continue to adjust the position of the nose clip; if air leaks from the edge of the mask, readjust the headband position. 4. If no leakage occurs, you can safely enter the work area.
