Fisher & Paykel Eson 2 Nasal CPAP Mask? the newest generation of Fisher & Paykel?s easy-to-use masks features a slim frame and headgear combination. It has the RollFit Seal that is designed to deliver an effective seal and precise fit by automatically adjusting on the bridge of the nose. The Eson 2 is built with the user in mind and its specifications are meant to provide maximum comfort to the users. F&P?s intuitive high-quality headgear is completely redesigned to provide excellent fitting options for patients while they also have the option to stretch the mask directly over the head. The Eson 2 features Easy Frame that has a narrow frame that comfortably fits all three size cushions and offers a clear line of sight while remaining stable. The full motion elbow moves in 360 degrees, thus decreasing the issues of dragging the mask. Assembling and dissembling the mask is also very easy with the VisiBlue. Adding to its comfort, the Fisher & Paykel?s innovative Eson 2 operates too silently to disturb the wearer as well as his bed partner, thanks to the washable diffuser.
