Face the front of the mask without the nose clip away from you, and pull the ear straps outward with both hands so that the nose clip is above the mask.
Cover your chin with the mask.
Pull each ear strap behind your ear, and adjust both the left and right straps so each feels comfortable.
Place the fingers of both hands on top of the middle of the metal nose clip and, while pressing inward, move the fingertips along the nose clip to both sides until the nose clip is fully pressed into the shape of the bridge of your nose. Using only one hand to pinch the mask nose clip may affect the tightness of the mask.
Before entering the work area, the user must check the tightness of the mask so that it adheres to the face.
Cover the mask with both hands to avoid affecting the position of the mask on the face.
Exhale quickly. If air leaks from the bridge of the nose, readjust the nose clip according to step 4. If air leaks from the edge of the mask, readjust the ear band; if a good fit cannot be obtained, repeat steps 1-4.
If there is no leak, enter the work area. It is important to press the nose clip firmly on the face to form a good fit.
Range of Use
The protective mask can be used for respiratory protection of certain non-oily particles; such pathogenic microorganisms include dust, sand, pollen, influenza virus, various types of productive dust, as well as non-volatile fog and other air pollution. It can be used as an environmental pollution protection against fine particles (PM2.5).
