Snugz Nasal Mask Liner Instructions & Tips

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

First, slide your hand through the mask liner with the black line towards your knuckles. Use your fingers to spread the liner open.

Next, stretch the liner over your nasal mask so that it covers the rubber mask cushion. Easy enough.

Then, pull the the end of your Snugz with the black line so that it extends about a half an inch (1.25 cm) past the rubber cushion.

Finally, use your thumbs to fold your Snugz inside the mask so that the black line is behind the inner edge of the mask cushion. That’s it. Really. Now go to sleep.

That’s it. Really. Now, go to sleep.

  1. Give your Snugz a few stretches before applying if you feel it is too tight on your mask.
  2. Make sure that the black seam is pushed inside of the mask enough so that it ends up behind the inner edge of the mask cushion.
  3. Note that the breathability of Snugz will leave you with a different sensation on your skin— your skin will feel cooler and dry. For some patients, this can take some getting used to, but it will help keep your skin irritation-free.


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.
