This replacement frame is for the Philips Respironics DreamWisp Nasal Mask. The frame is made of latex-free silicone and is used to deliever CPAP air flow to the nasal cushion. The light and flexible frame has 2 slots at the top and 2 circular openings at the base to connect the headgear. Optional fabric wraps can be used to soften the side sections even more. This frame is a one size fits all, but can be adjusted by purchasing a different size Connector. The Connector is used to attach the left and right frame sections at the top of the head. If the mask frame falls backward and is too close to your ears, you may need a smaller sizing connector. If the mask frame falls forward on the head and is too close to your eyes, you may need a larger sizing connector.
