Zest CPAP Mask Parts & Replacements

The Fisher & Paykel Zest nasal mask has earned a loyal following for its lightweight frame and forgiving fit — but like any CPAP mask, its cushions, seals, and headgear wear out with nightly use. This collection brings together the genuine replacement parts that keep your Zest, Zest Q, or FlexiFit setup sealing quietly and comfortably, so you don't have to replace the entire mask when only one component is worn.

Most Zest users find the silicone seal and foam cushion are the first parts to go, softening and losing their leak-tight fit over months of use. The Fisher & Paykel Easy-clip Silicone Seal and Foam Cushion (400HC542) in Standard size restores that quiet, stable seal in seconds — no tools, just clip and go. If comfort has slipped because the straps have stretched, the Stretchgear Headgear (400HC314) fits across various FlexiFit, Zest, and Zest Q series nasal masks, giving you back secure, even tension without over-tightening.

Starting fresh or need a smaller fit? The Zest Mask Kit without Headgear with Petite Cushion (400HC559) includes the frame and cushion, letting you pair it with headgear you already own — a practical choice if your current straps are still in good shape or you want a more contoured seal for a smaller nose bridge.

A common question: how often should these be replaced? As a general rule, cushions and seals every 1–3 months and headgear every 6 months, though heavy use or facial oils may shorten that. Replacing on schedule protects therapy pressure and skin comfort alike. All parts here are single-patient-use and made for the Zest system specifically, so sizing and clip compatibility are straightforward.
