After a few months of use, the nasal mask cushion softens and air starts to leak towards the eyes. The reflex is to tighten the headgear, but this eventually puts pressure on the bridge of the nose. Replacing the Mirage FX cushion restores the original seal without having to buy a whole new mask.

• The cushion is the only part that touches the skin, so it's almost always the reason for recurrent leaks.
• It removes and replaces on the existing frame, without tools and without readjusting the entire assembly.
• A cushion in good condition maintains a seal with looser headgear, meaning fewer marks upon waking.
