Fisher & Paykel Simplus Full Face CPAP Mask Parts

If you rely on a Simplus full face mask for your CPAP or BiPAP therapy, worn headgear and a tired cushion are usually what stands between you and a good night's sleep. This collection carries the genuine Fisher & Paykel Simplus replacement parts that keep your existing mask sealing properly, so you don't have to buy a whole new system to fix a leak or a stretched strap.

The heart of the Simplus is its RollFit seal. The Simplus RollFit Seal in Large (400HC581) auto-adjusts as you move, rolling on the bridge of the nose to accommodate different face shapes and reduce pressure points and red marks. Because the cushion is the part that wears out fastest — silicone softens and loses its seal over months of nightly use — most people replace it well before the frame or headgear. A fresh seal is the quickest way to stop air leaks around the nose and mouth.

For the fit that holds it all in place, choose the breathable Simplus headgear in Small (400HC582) or Medium/Large (400HC583). The open, spacer-fabric design wicks moisture and stays cool, and the straps hold their tension longer than fabric that has been washed and stretched dozens of times. If your mask lifts off your face or you're cranking the straps tighter than they should go, the headgear — not the cushion — is often the culprit.

How often should you replace these parts? A general guideline is a new cushion every one to three months and new headgear every six months, though it varies with how you clean and store them. Sizing on the seal and headgear is independent, so you can mix a Large RollFit seal with Small headgear if that's what fits your face and head best.

All items here are authentic Fisher & Paykel components made specifically for the Simplus full face platform — no third-party guesswork about compatibility. Keep a spare seal on hand so a sudden leak never costs you a night of therapy.
