Place OmniMask over your nose and mouth, then pull headgear over the crown of your head.
Attach the lower end of the straps behind your neck.
If this is your first time putting on your mask, adjust the length of each strap to fit using the tri-glide buckles. If there is significant excess material, you can trim it with scissors. We recommend using a heat source to seal the end of the fresh cut to prevent fraying over time.
First on one side and then the other, reach behind the side filters and pull some of the strap length from the headgear area to the neck section. The pressure in the headgear area and neck sections should feel balanced and very light when the straps are properly adjusted.
