This is the RollFit Seal Nasal Cushion Replacement to be used with the Eson 2 mask from Fisher & Paykel. The RollFit design actually “rolls” back and forth and adjusts on the bridge of the nose automatically. This unique design helps to reduce pressure on the bridge of the nose, which is a common problem with CPAP masks. This feature enhances better fit and seal.
