The nasal cushion from Respironics is compatible with all DreamWear Nasal CPAP Masks. There are four cushion sizes available -- Small, Medium, MediumWide & Large.
The DreamWear mask's nasal cushion rests under the nose, providing airflow to both nostrils without inserting into them. Because of the cushion's low profile design there is absolutely no contact on the top of the nose or at the sensitive nasal bridge.
USAGE: Any cushion size will fit on any DreamWear 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.
