This Whisper Swivel is used to remove excess waste gasses from some older Respironics CPAP/BiPAP masks. It should only be used on Reusable Silicone Contour Masks, Gold Seal Masks, and some older ProfileLite Masks that did not come with a swivel.
Respironics Simple Strap Headgear is designed as an alternative headgear for many nasal and full face CPAP/BiPAP masks. It will work with most Comfort Series masks as well as the ProfileLite, Gold Seal and reusable Contour masks. It includes a QuickClip to make the headgear easier to put on and take off without losing your size adjustments.
