"The DreamWear Full Face CPAP interface is like wearing nothing at all, making it the most comfortable Full Face CPAP interface on the market today, delivering a great seal and stability needed for a good night’s sleep. Philips Respironics new and exciting design is the soft silicone frame that directs airflow through two silicone tubes to join at the full face cushion. Because the frame is soft and flexible it adapts naturally to facial contours without pinching or pressure points, and will accommodate almost any sleeping position, giving you more freedom of movement, and a wide open field of view. A real plus among CPAP users. Unlike most full face interface that rest on the bridge of your nose the DreamWear Full Face interface fits just under the nose, providing a secure seal without all the annoying red marks on the top of your nose, discomfort or irritation in the nostrils. Features: • Silicone Frame: The soft frame directs airflow through two silicone tubes to join at the full face cushion. The frame is soft and adapts naturally to facial contours without pinching or pressure points, and will accommodate almost any sleeping position. • Under the Nose Cushion: The interface's full face cushion rests under the nose, providing airflow to both the mouth and nostrils without actually inserting into the nose. There is absolutely no contact on the top of the nose or at the sensitive nasal bridge. Exhalation ports on the cushion, and in the interface's elbow, quietly disperse excess air. • Headgear and Tubing: Soft, single strap headgear rests at the back of the head, stabilizing the interface without requiring over-tightening or excessive contact. The tubing elbow is located on the top of the head where it can swivel freely to help reduce drag. • Open Field of View:The interface provides the user with an open field of view for reading, talking or watching TV before bed. • Cushion Sizes:The full face cushions are available in four sizes, Small, Medium, Medium-Wide & Large, to fit a wide range of noses. If you're unsure of which size to choose, download the sizing guide available elsewhere on this page to determine your best fit. All DreamWear parts are interchangeable so any cushion will work with any frame size."
