The Rhinomed Mute Nasal Dilator for Snoring Reduction is a soft, pliable polymer stent that dilates your nose. Mute increases the volume of air travelling through the nose during sleep, encouraging nasal breathing to alleviate congestion - factors critical to help stop snoring and for a better quality of sleep. Mute has been proven in clinical trials to increase air flow through nasal passages, on average, up to 38% over nasal strips. Made from ultra-soft medical grade bio-compatible polymers conforming to the strictest medical standards, Mute stays in place throughout the night. Mute comes in three different sizes, and each device has individually adjustable left and right stents to further refine the fit. Mute nasal dilator units can be reused approximately ten times.
