Both the Nose Cones® and Sinus Cones® are a reliable and simple solution to maximize nasal breathing during sleep. They will help to alleviate mouth-breathing dependency that will result in snoring and oral-care issues associated with nighttime dry mouth. They can also be used to help treat obstructive sleep apnea inside a CPAP mask or in conjunction with an oral appliance to maximize nasal airflow and airway patency. Specifically, the Nose Cones treat milder breathing difficulties, such as those occurring only during sleep, and the Sinus Cones treat more severe airway collapse, obstruction, and chronic sinus/nasal congestion.
