resplabs CPAP Mask Liners Full Face Masks sleepliners, AirFit F20 Style Liner, Medium 4 Pack

REDUCES MASK LEAK AND RED MARKS: The cotton liner sits between your skin and the F20 silicone cushion. You get a better seal without cranking your headgear tight. Most users notice fewer air leaks and less facial redness from the first night. CUT SPECIFICALLY FOR THE F20 MEDIUM: This isn't a generic sheet you trim with scissors. It's pre-shaped for the ResMed AirFit F20 and AirTouch F20 cushion in Medium. Stretches over the cushion in about 10 seconds. REUSABLE, NOT DISPOSABLE: Each liner lasts 2-3 nights before washing. Machine wash cold, air dry. The 4-pack gives you 2-4 months of liners at pennies per night. Most competitor liners are single-use felt pads that you throw away every morning. YOU CAN ACTUALLY LOOSEN YOUR STRAPS: Here's what most people don't realize. The liner adds surface area between your face and the cushion. That means the mask seals with less strap tension. Less tension = fewer pressure lines on your cheeks and nose bridge. SIZED FOR YOUR SPECIFIC F20: This is the Medium. We also make Small and Large because fit matters with liners. Check the size printed on your mask frame if you're not sure.
