Using clean hands, unfold and open the mask with the nose clip at the top, pull the ear straps apart with both your hands.
Hold the bottom edge of the mask against your chin and the nose clip across the upper bridge of your nose to completely cover your mouth and nose.
Pull the ear straps behind your ears and adjust them until they feel comfortable.
Use both hands to adjust the shape of the nose clip. Place the tips of the thumb and forefinger of one hand at the middle of the nose clip and press inwards while moving your fingertips along both sides of the clip to form it to the bridge and sides of your nose. Repeat with the thumb and forefinger tips of your other hand to achieve a more even, secure seal.
Cover the mask with your hand and exhale vigorously. If you feel the air escaping from the nose clip, tighten the clip again following the process in step 4. If you feel air escaping from the sides of the mask, readjust the ear loops.
