Step 2: Fix the mask so that the metal brace is parallel to the bridge of the nose, the bottom edge of the mask is below the chin
Step 3: Pull the strap and fix it behind the ear, adjust the edges of the mask to make the user feel most comfortable.
Step 4: Use the fingertips in both hands to adjust the metal bar, gently squeeze the metal bar inward to increase the tightness of the mask. Do not use one hand to operate because it will reduce the dust filtering efficiency of the mask.
Step 5: Check the tightness by placing your hands on the mask, being careful not to move the mask. Inhale strongly, if air leak is felt, go back to step 3 to adjust the strap and step 4 to adjust the nose brace. If the mask is flattened inward, the mask is already tight to the face
