Fisher & Paykel Eson Nasal CPAP Mask

The original Fisher & Paykel Eson nasal mask with RollFit self-adjusting seal and three-part design. Replacement seals and headgear available. Note: parts are NOT compatible with the Eson 2. Small, Medium and Large.

The Fisher & Paykel Eson is the original Eson nasal mask — a compact, three-part design built around F&P's RollFit™ seal that self-adjusts on the nasal bridge as you sleep. A proven and well-liked mask among long-term users, the Eson remains a solid choice for existing wearers who know it works for them and want to reorder or replace parts. Replacement seals and headgear are available separately.

Key Features

• RollFit™ seal — the silicone cushion rolls back and forth on the bridge of the nose in response to your movement during sleep, automatically adjusting to maintain a consistent seal and minimise pressure on the nasal bridge; the same core technology that underpins the updated Eson 2
• Three-part design — simple to clean and reassemble — the mask consists of just three main components: the cushion, the headgear, and the frame; disassembly for daily cleaning is quick and reassembly is straightforward
• Compact, low-profile frame — the slim frame sits close to the face with minimal contact points and a clear field of vision; no forehead support pad or bulky headgear architecture
• ErgoForm™ headgear — breathable stretch and non-stretch headgear panels provide structure and comfort; the headgear self-locates high on the rear of the head, allowing natural head movement without dislodging the mask
• Three sizes — available in Small, Medium, and Large cushion sizes

Who Is This For?

If you are new to CPAP therapy and considering an F&P nasal mask, the Fisher & Paykel Eson 2 is the updated version with over 20 design improvements — including a lighter RollFit seal, an eco-friendly washable diffuser, and improved headgear — and is the recommended starting point for new patients. For the newest F&P nasal mask technology, the Fisher & Paykel Nova Nasal Fit Pack features SwingFit one-click headgear and an updated RollFit cushion.
