This nasal cushion from Respironics is designed for use with all Wisp CPAP & BiPAP Masks. Four cushion sizes -- Petite, Small Medium, Large & Extra Large -- are available.

The Wisp's hybrid cushion design was created by combining the comfort of a nasal mask with the minimalism and seal of a nasal pillow mask.

USAGE:

Any cushion size will fit on any Wisp CPAP mask frame so if you find you want to try a different size you can simply purchase a new cushion rather than having to buy a whole new mask.
