Featuring a flexible and lightweight gel nasal cushion, the Philips Respironics ComfortGel Blue Nasal CPAP Mask covers your nose and is anchored in place by a forehead pad to create a reliable and secure seal. To achieve a peaceful night of quiet sleep, the ComfortGel Blue's angled exhalation micro ports direct exhaled air out and away from you and your partner, while the redesigned ComfortGel Blue mask reduces red marks and causes less irritation by conforming to the contours of your face.
