This Dual-Wall Spring Air Cushion is designed for use with all Mirage FX & Mirage FX For Her CPAP and BiLevel Masks. Each Dual-Wall Spring Air Cushion is coated with soft-touch frosting to provide comfort and even pressure distribution. The unique design provides an even softer texture and removed undercushion at the nasal bridge to reduce the pressure, soreness, irritation and discomfort commonly felt in this senstitive area. At the front of the Mirage FX's Spring Air cushion is an in-moulded vent ring that disperses air gently and quietly away from the user and bed partners.
SIZING: Mirage FX Series masks use a different frame size for each cushion so you should only purchase the correct cushion size for your mask frame. Cushion size is indicated on the bottom of each cushion. If your current cushion label reads "Mirage FX" then it is a Standard cushion; if it reads "Mirage FX Wide" it is a Wide cushion; and if it reads "Mirage FX Small" then it is a Small cushion.
