The DreamWear Full face mask was designed to provide a better option for sleep apnea patients who breathe through their mouths. To help combat the challenges that come with wearing a CPAP mask, Philips designed the new DreamWear Full face mask so the cushion sits under the nose, not on it. This makes it feel like there’s nothing on the face! The goal of this mask is to give patients the best chance of long-term therapy success. This mask is the large frame.
