This is the replacement cushion for the ResMed Activa LT Nasal Mask and for the ResMed Mirage SoftGel Mask. The cushion includes the cushion clip as shown.

ActiveCell Technology accommodates movement during sleep, which results in fewer mask leaks for restless sleepers. The bubble-like membrane surrounding the dual-wall cushion expands and contracts to varying pressures and allows for different sleeping positions during the night. The new ActiveCell membrane is less cumbersome than the original, but still prevents CPAP users from over-tightening the mask headgear to create a secure seal. A looser fitting mask reduces pressure points and prevents red marks.
