Many people tend to open their mouths at night while using nasal and nasal pillow masks for CPAP and Bilevel therapy. ResMed's chinstrap gently holds your mouth closed at night, eliminating issues like snoring, dry mouth, and air swallowing. Not only does this result in more effective therapy, but can also improve your sleep. This chinstrap fits over and under a massive range of CPAP masks, so you can continue using your favourite mask without any issues.

Plus, maintenance is a breeze. The same neoprene that makes the chinstrap so comfortable is washable with warm water and mild detergent.
