This is a replacement cushion for the Fisher & Paykel SImplus Full Face CPAP. The cushion comes in three sizes: small, medium, and large.
RollFit Seal Feature
Fisher & Paykel's RollFit Full Face Seal is designed for use with all F&P Simplus CPAP. As the name suggests, the RollFit Seal rolls back and forth on the nose, auto-adjusting during sleep to reduce pressure on hard to fit areas, like the bridge of the nose, while increasing overall seal and comfort.
The RollFit Seal incorporates integrated stability panels for optimal sealing performance and stability all night long.
SIZING:Three Simplus RollFit Seal sizes are available -- Small (400HC579), Medium (400HC580) & Large (400HC581). All Simplus use a single frame size so any seal size can be used on any frame. If you would like to change the size of your mask, you can just purchase a different seal size and fit it to your existing frame.
USAGE:Simplus RollFit Full Face Seals are made up of two parts -- a silicone seal and an acrylic shell. The two parts CANNOT be separated.
