The DreamWear masks full face cushion rests under your nose, and provides airflow to both the nose and mouth without actually inserting into the nostrils or exerting any excess pressure. There is absolutely no contact on the top of the nose or at the sensitive nasal bridge, like a typical full face cushion, because of this cushion's low profile design.
Usage Information: Full Face Cushion size is indicated with an abbreviation (i.e., M for Medium, S for Small, etc.) in black on the side of the cushion. A black arrow next to the size indictor helps to determine proper placement of the cushion in the mask frame. Any cushion size will fit on any DreamWear Full Face mask 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.
