Snugz Mask Liners, by WakeWellReviews of sleepsnugz.com

This C-pap full mask liner did decrease mask leaks, but it was warmer on my face than my mask without this liner and for me I did not like it. It also for me still left red mask lines after I got up.

Advertised to fit most masks. I have to stretch it beyond belief to fit my large airfit20. It’s a struggle every night

When first used felt comfortable however in middle of the night when I got up to go to bathroom it seemed the fabric had fluffed up and it felt suffocating. Removed for reminder of the night.

They are slipping off.

They are comfortable but they are a bit of a stretch to get them over the face mask and to get them to cover all of the plastic parts of the mask that would irritate your skin. I tried to make my own using a pair of old socks, but the mask liner couldn't go around the full mask fully without lots of excess material that makes you feel claustrophobic when using the mask. These snugs ones are good enough, but not seen how they wash yet.

I really wanted to give more stars and maybe this would work with bigger masks… I have just a nasal mask and this liner bunched up underneath and filled my mask making it hard to breathe. I tried adjusting it but there was just too much material.

Bought to reduce red lines from a full face mask. Still have the red lines

Not sure it is me or not but I don’t believe that one size fits all. I have a medium full face mask it seems to small and squishes tha mask too much. I will give it a few more tries.
