Continuous positive airway pressure (CPAP) therapy can be an effective treatment for people with sleep apnea. CPAP machines use pressurized air to prevent airway collapse and decrease sleep apnea symptoms. A hose and mask deliver the air to the user’s breathing passages.

Some CPAP masks have a full-face design, while nasal masks cover just the nose. CPAP liners work with both mask options. Though they are not required, mask liners can increase comfort and prevent irritation. Many people prefer the soft, smooth fabric of a liner to the silicone cushion of a CPAP mask. Liners can also help cut down on excess moisture, which can be particularly helpful for hot sleepers and those who use a CPAP humidifier.

We’ll discuss our picks for the best CPAP mask liners, explaining what they’re made of, how they fit, and what types of masks they are compatible with.

While liners for full-face masks are more common, you can also alleviate discomfort from your nasal pillow CPAP mask by using a liner. These disposable liners from RemZzzs are exclusively designed for nasal pillow masks. Made of pure cotton, the liners are soft enough to glide across the skin and reduce blisters and red marks that can occur around the edges of your mask. The cotton is also highly breathable, so you shouldn’t overheat during the night.

Noise suppression is another notable trait. By forming a buffer between your nose and the mask, the liner can minimize noise that occurs due to air leaks. The liners are compatible with most Philips Respironics, ResMed, and DeVilbiss nasal pillow CPAP masks.

The liners are disposable and intended for one-time use. Each package includes 30, so your purchase should last about one month if you use CPAP therapy every night. RemZzzs also offers liners for full-face CPAP masks.

How to Choose a CPAP Mask Liner

There are a few things to keep in mind while shopping for CPAP liners. The first consideration is whether or not a liner is compatible with the mask you already own. Due to the varying shapes and sizes of CPAP masks, most mask liners are not one-size-fits-all. Choose a liner that’s designed to work with your mask. Also consider other factors like price, fabric, quality, and cleaning instructions.

What to Look For in a CPAP Mask Liner

Some companies that produce CPAP mask liners use industry jargon or marketing buzzwords to sell their products. It’s critical to look past these phrases and think about your individual needs.


The cost of a CPAP mask liner ultimately depends on its materials and quality. Most models are reusable and washable, and higher-end liners tend to hold up better to wear and tear. You should expect to pay at least $15 for a CPAP mask liner. Average liners work for about three months before needing replacement, though some can last as long as a year.


With the large variety of CPAP masks on the market, it’s important to choose a liner that’s compatible with the mask you own. If you choose one that’s not, the breathing cutouts might not line up with your mouth and nose. Retailers typically list which masks the liner is compatible with in the product description.

Moisture Wicking

Some CPAP mask liners are made from moisture-wicking materials. These fabrics help keep you dry and cool by drawing excess moisture away from your mouth and nose. Fabrics like microfiber and microfleece are particularly well suited to this task.

Quality Materials

Choosing a mask liner that’s made with high-quality fabric can help ensure that it lasts. Top-notch liners can have a lifespan of up to a year if cared for properly. Masks made with quality materials are much more likely to withstand machine-washing as well as normal wear and tear.

Cleaning and Care

Reusable mask liners should be cleaned at least once a week. Many models can be machine-washed, but avoid drying them with a high heat setting. For liners that require hand-washing, use a gentle facial soap and soak the liner, then lay it flat to dry.

What Is a CPAP Mask Liner?

A CPAP liner is a fabric barrier that fits snugly between your CPAP mask and face. The fabric protects your skin and ensures the mask doesn’t irritate your face or leave marks.

Depending on which type of liner you choose, it may also have moisture-wicking or cooling properties. Most liners are reusable and washable, though not all can be machine-washed. Using a CPAP liner can improve your comfort while sleeping and can help keep your CPAP mask clean and hygienic.

Frequently Asked Questions

How do you use a CPAP mask liner?

To create a barrier between your face and CPAP mask, wrap the CPAP mask liner around your mask and fasten it shut. Each liner fastens differently according to the mask's unique design. Some use Velcro, while others simply slide around the mask. Read your liner's instructions before use, as each one fits a bit differently.

Do CPAP mask liners help with leaks?

If worn correctly, CPAP mask liners can help cut down on leaks by preventing the mask from shifting on your face. However, you still need to ensure that the mask fits properly and that your pillow or sleeping position doesn’t interfere with your CPAP device.If worn correctly, CPAP mask liners can help cut down on leaks by preventing the mask from shifting on your face.

What are CPAP mask liners made of?

To hand-wash, fill a basin with lukewarm water and facial soap, then submerge the liner and gently scrub. Rinse it and squeeze away excess water, laying it flat to dry.
