Features

• TROUBLE SLEEPING? Manage your expectations. As we understand it, the primary purpose of a CPAP machine is not to help you fall asleep; it is meant to help you breathe. However, once asleep, Continuous Positive Airway Pressure can help you stay asleep.
• THE PROBLEM: CPAP masks are meant to be comfortable; often they are not. Air leaks, skin irritation and red pressure marks can make it difficult to sleep comfortably and stay on therapy.
• THE SOLUTION: See size charts at left. Since 2015 we are the original American made, blue, soft cotton/polyester blend CPAP mask liners that help reduce air leaks and skin irritation.
• WHAT YOU GET: No prescription required. Two CPAP Comfort Covers included in every package. Wear one while you launder the other. They can last a long time. This makes them less expensive than having to re-buy disposable mask liners. Mask not included.
