CPAP and BiPAP machines require different accessories for effective treatment of sleep apnea. These supplies include nasal masks, tubing, and cleaning wipes. It is important to regularly clean your CPAP supplies so that they work properly. Express Medical Supply carries disposable mask wipes that quickly and conveniently sanitize your CPAP mask. Keep in mind, even with regular cleaning these accessories will need to be replaced every few months or as directed by your pulmonologist.
