NOZOVENT Free nose Stop Snoring Well being Stop snoring and improve nasal breathing. Snoring not only disturbs the sleep of others, but also disturbs the quality of sleep of the snorer, with consequences for their well-being and health. Nozovent dilates the narrowest and most flexible part of the nostril. This has the effect of decreasing the speed of air passing through the nostrils by increasing the volume of air, making breathing easier. As a result, the soft palate does not vibrate as easily. The effort to breathe is less and snoring is reduced.
