CPAP chin straps are designed to keep your mouth shut throughout the night during therapy. If you use a nasal or nasal pillow mask and breathe through your mouth, or your mouth tends to open while you sleep, it can cause pressure leakage and reduce the quality of your therapy. Chin straps for CPAP help prevent pressure leakage and side effects like dry mouth and sore throat, making therapy more comfortable and effective. Made from soft, adjustable materials, they wrap around the top or back of your head for a secure fit. If you're trying to switch from a full face to a smaller mask or you struggle with pressure leaks, chin straps are a great option to help you better manage your sleep apnea. If you already use one, we recommend replacing it once every six months.
