This is the replacement cushion for Respironics DreamWear Full Face CPAP Mask. Exhalation ports on the cushion, and in the mask elbow, quietly disperse excess air. The DreamWear mask full face cushion rests under the nose, providing airflow to both the mouth and nose without actually inserting into the nostrils or exerting any excess pressure. Because of the cushion low profile design there is absolutely no contact on the top of the nose or at the sensitive nasal bridge.Features :- Designed for a cozy, custom fit air tube connects at the top of the head instead of at the nose bridge for extraordinary comfort. Lightweight in frame airflow design. Provides more freedom during the night.
