This is the replacement cushion for the Mirage FX Nasal CPAP mask. The gel cushion is comfortable, and the replacement will attach easily to your mask.
Spring Air Technology
ResMed's patented Spring Air technology makes your cushion lightweight and unobtrusive. Unlike some cushions, the cushion for the Mirage FX is filled with air on the inside, so it's less bulky and more comfortable than most cushions. Additionally, the gel pad won't rub up against your face, and won't leave facial blemishes.
