Bongo Rx is a CPAP alternative that eliminates the use of a CPAP machine, mask, or hose. This all-new device is an FDA cleared, prescription device that focuses on treating mild to moderate obstructive sleep apnea (OSA) in patients who naturally breathe through their nose. These nasal cones are designed for patients who have already used the Bongo Rx Starter Kit and are looking to replace their current nasal cone. Available in 4 replacement sizes: Small, Medium, Large, or Extra Large. For best results, it is recommended to replace these seals every 90 days to continue receiving the full benefits of the Bongo Rx.
