If the seal on your Philips Respironics ComfortFusion Nasal Mask seems to be losing its effectiveness, or is simply less comfortable than it used to be, then it may be time to change the silicone cushion on your mask.

Over time the cushion can become worn, lessening its stability and purchase. However, to make your ComfortFusion function as well as it did when you first got it, all you need to do is replace the cushion, rather than buy a complete new mask.

There are two sizes to choose from. Select whichever size corresponds to the size of your mask.

The cushion comes supplied with a new retaining ring.
