Introducing F&P Eson™, Fisher & Paykel Healthcare’s nasal mask, designed to perform in tune with you and your needs. The RollFit™ seal, ErgoFit™ headgear and Easy Frame all work in harmony. The RollFit seal adjusts automatically by rolling back and forth on the bridge of your nose for a comfortable fit. The ErgoFit headgear is designed to self-locate high on the rear of the head, allowing for movement. The low-profile Easy Frame is stable and durable, and ensures a clear line of sight.
