Improved Gel Cushion Technology: Respironics has improved the ComfortGel material. The gel is now softer and conforms to your face with greater ease. Use the separate silicone membrane that snaps on, over the gel cushion, to increase the life of the cushion and provides a unique Sure Seal Technology (SST), contouring a seal around the Gel Cushion.
Premium Forehead Pad: The ComfortGel forehead pad is larger with more cushioning that is easy to fit and improves comfort. The forehead support comes with a StabilitySelector, which is adjustable and allows for movement. The pad attaches to a base that can swivel up or down; accommodating the angle of your forehead.
Angled Exhalation Micro Ports: The new diffusion vent and 360 Degree elbow disperses air softer and quieter than before. The elbow angles the ports away from your bed partner and the micro size diffuses airflow quietly, reducing overall sound.
