The ResMed Mirage FX nasal mask offers the perfect balance of lightweight comfort and simplicity. Built with patients’ convenience in mind, the Mirage FX is made up of only four parts, making it easy to clean and re-assemble. It's also engineered to deliver maximum comfort while patients sleep - the dual wall, Spring Air™ cushion is soft on the face, and the ultra-flexible forehead support reduces contact with the skin.
