Regular use causes a CPAP cushion to eventually lose its ability to form a perfect seal. This replacement cushion for the Fisher & Paykel 407 nasal mask is simple to install, so you can quickly improve the quality of your treatment. The FlexiFit design allows the cushion to fit petite, wide, and unique facial structures, allowing everyone to have a comfortable fit. Adjustable and tapered velcro straps keep the seal stable for light and active sleepers. Enjoy peace of mind with a Remologie Sleep Club subscription! We will send you the supplies you need when you need them. You'll never have to worry about ordering sleep apnea product replacements again.
