Are you looking for a product that will perform in line with what you need? The breakthrough for Fisher & Paykel Healthcare offers an interface that is low maintenance but still meets your needs. It is made out of three small parts that all work together to provide comfort and great performance. The seal on this is extremely good with very low leakage levels and was the number one nasal interface for a long time. This has now been superseded by the Eson 2 but this is still is popular with many users. Made of three components, the interface is easy to fit. The Rollfit seal allows for the cushion to self-adjust on the nose bridge easily. Additionally, to further aid stability, it has Integrated Stability Panels that offer sealing stability throughout the night. The headgear has been designed in such a manner that it can self-locate while worn, to allow the head to move around which prevents dislodging. The frame is a one size fits all, but stays out of the line of vision. The frame has a ball and socket joint that allows for the frame to move freely.
