Step 1 - Remove head strap from the mask.

Step 2 - Open both velcro straps so that the clips can slide freely on the head strap.

Step 3 - Pull the strap around the crown of your head.

Step 4 - With velcro still open, slowly pull the magnetic clips down to the base of your nose. The strap should now be at the appropriate length for your head.

Step 5 - Secure the velcro so that the straps can no longer slide on the head strap.

Step 6 - Take your mask. Notice the small notch in the face seal. This is the top side of the mask.

Step 7 - Attach one of the magnetic clips to either side of the mask. Place the mask on your face and pull the strap around the back of your head.

Step 8 - Attach the clip to the mask.

Step 9 - If necessary, adjust the mask so the bottom is sitting at the base of the chin. The mask should not be sitting too high on the face or nose.

The mask should be snug but not too tight. Remove the velcro and readjust the length of the head strap if necessary.

Some customers prefer to wear the head strap around the neck and under the ears.
