When a cushion wears out, leaks and nightly adjustments often follow. The Fisher & Paykel Simplus Full Face Mask Cushion restores a dependable seal so you can focus on therapy rather than fussing with fit.
Built specifically for the Simplus Full Face Mask, this replacement cushion features a RollFit seal with integrated stability panels that bend and flex as you move during sleep. The RollFit design allows the cushion to gently roll on the skin rather than sliding or lifting, helping maintain therapy pressure and a consistent seal throughout the night. The silicone cushion is attached to a clear acrylic frame as a single unit and clicks directly into your existing Simplus mask frame.
Available in Small, Medium, and Large. All three sizes fit the Simplus Full Face Mask frame. The size is embossed on the cushion profile near the bridge-of-nose area for easy identification when reordering.
Note: This is a replacement cushion only. The silicone cushion is attached to a clear acrylic frame and cannot be separated. The Simplus mask headgear, elbow, and other components are sold separately.
RollFit Seal Technology — The cushion gently rolls on the skin as you move, maintaining seal alignment without sliding or lifting for fewer leak interruptions.
Integrated Stability Panels — Built-in panels bend and flex with your facial movements, helping limit shifts and maintain steady therapy pressure throughout the night.
Click-In Installation — Align the cushion with your Simplus frame and press until you hear a click. No tools, no complicated assembly.
Three Sizes, One Frame — Small, Medium, and Large all fit the same Simplus mask frame. Match your size and click in for a refreshed seal.
One-Piece Cushion Unit — The silicone cushion is permanently attached to a clear acrylic frame, ensuring proper alignment and seal geometry every time.
