How to Adjust the fit of the ResMed Quattro FX Full Face Mask?

Place your mask against your face with the lower headgear clips released. Position the mask so the top of the cushion rests on the bridge of your nose and the lower portion sits between your bottom lip and chin.

As you hold the cushion in place, pull the headgear up and over your head. Feed the lower headgear straps beneath your ears and clip them into place on the cushion frame.

Use the Velcro straps to adjust your headgear so the mask sits securely on your face. Don’t overtighten; pulling too tightly will create face marks and may result in air leaks during therapy. The mask should feel secure, yet still, be able to move with you as you change sleeping positions.
