The ComfortGel Blue Medium Nasal CPAP Mask by Respironics has angled exhalation micro ports to help reduce airflow noise. This is a nasal mask that covers solely the nose to deliver air. The ComfortGel nasal mask frame has not changed, so the new ComfortGel Blue Nasal Cushions and Original Gel Nasal Cushions are interchangeable. The headgear is not included.
