Using Snugz couldn’t be any easier. Here’s how:

First, slide your hand through the mask liner with the black line facing inward, touching your fingertips. Use fingers to spread the liner open.

Next, hook the upper outer edge of the mask liner over the top of your mask. The black line should be facing the mask. Easy enough.

Then stretch the mask liner to secure over the other rounded corners of the mask. Almost there!

Finally, achieve your desired mask coverage and comfort through minor tugging adjustments.

That’s it. Really. Now, go to sleep.


Snugz are low maintenance. Simply toss me in with your regular laundry between uses to keep me fresh. And, yes, you can throw me in the dryer as well. Don’t worry, I can take the heat.


  • What if I feel or my CPAP machine shows air leaks?
  • A better seal does not necessarily mean a more airtight seal. Snugz provide a better seal by allowing some “micro-leakage” through the fabric. This breathability not only keeps your mask feeling cooler, but prevents a sweaty, slippery mask cushion interface that will inevitably slip and lead to loud noisy leaks that wake you up. With Snugz, those leaks should be greatly reduced, if not eliminated, and your sleep quality should improve. Your CPAP machine may register some leakage and it may be possible to feel some leakage through the Snugz fabric. Modern CPAP machines, however, automatically adjust for such leakage and what matters most is your AHI and having fewer disturbances.  While it’s always smart to check with your care provider, if you are sleeping better with reduced disturbances, and your AHI is low, your Snugz is doing its job.
  • Do Snugz restrict airflow?
  • When properly placed on your mask, Snugz should not restrict air flow. Adjust your Snugz to cover only the silicone cushion of the mask and not your nostrils or mouth. Also, make sure that the CO2 exhalation ports (a set of small holes usually located on the front of the mask) are clear and not blocked or restricted. These ports are the only place you should feel air escaping. Again, if you have any questions or concerns, please talk to your sleep professional.
  • What type of cloth is used to make Snugz?
  • Snugz are proudly Made in America using a blend of spandex, moisture-wicking polyester and lycra fibers. Snugz are latex free.
  • Do Snugz contain latex?
  • No. Snugz are latex free.
  • Are there different sizes of Snugz?
  • No. Snugz is a “one-size-fits-all” liner for most full face CPAP masks. (Currently, we do not have a Snugz for the Respironics Amara View Full Face Mask. But, we’re working on it!) If you find any full face CPAP masks that do not work with Snugz, please let us know!
  • Do Snugz work on any type of CPAP mask?
  • Snugz Full-Face Mask Liners will fit all nose-and-mouth masks except for the ResMed Mirage Quattro and the Fisher & Paykel Forma XL.  They also not recommended for under-the-nose style masks such as the Respironics Amara View or DreamWear and the ResMed F30, or total face masks such as the Respironics FitLife.
  • Snugz Nasal Mask Liners will fit all nasal masks, but are not intended for nasal pillows (under the nose).
  • How many Snugz come in a pack?
  • Snugz come in packs of two. We recommend having at least one for each day of the week so that you can wash them all with your weekly laundry.
  • How do I care for my Snugz?
  • Snugz are low maintenance. Simply toss them in with your regular laundry between uses to keep them fresh. And, yes, you can throw them in the dryer as well. Feel free to use fabric softener to keep Snugz soft. Steer clear of harsh chemicals and bleach as they may irritate the skin. We recommend having at least one Snugz for each day of the week so that you can wash them all with your weekly laundry.
  • How long do Snugz last before I need to replace them?
  • Unlike other products, Snugz are made to last. They hold up well to regular laundering. For the best Snugz experience, replace them every 90 days to keep them soft, fresh, and working well.
  • Does insurance cover Snugz?
  • Not at the moment, but we are working on it!

Warnings / Cautions: If at any time you are concerned that Snugz is interfering with therapy or causing increased irritation/discomfort, stop using Snugz and ask your sleep professional.
