Snugell CPAP Mask Liners Full-Face (4-Pack) – White – Compatible with F20 and Most Full Face Masks – Soft Cotton Fabric CPAP Skin Protector for Universal Fit – Reusable & Washable for 6-Month Supply

Fits my mask perfectly. Works great

"Universal" fit is like saying one size fits all or most. I use a small size face mask, but I find this only covers the plastic exterior of the face mask, and doesn't cover the foam interior that rubs skin. I don't feel like it is effective to minimized air leaks or give comfort to skin. The cotton fabric is like quality T-shirt material, which is why I chose to purchase this product, but I find they don't use enough fabric to work well.

They work one time but once the fabric is stretched, they're useless.

Great for folks who don't like the feel of the mask touching your face all night. I've got oily skin and drool when I sleep. These things do affect the mask seal, slightly... but the advantages far outweigh the slight reduction in functionality for me. Machine washable too, but they're made of cotton and will shrink a bit in the dryer. You'll need to play around with the fit, over your mask, but it made sleeping much more comfortable, and I feel less gross in the morning.

The liner has thick elastic that goes over the top of the mask, but nothing to hold it in place on the side where it meets the cushion, and your face.This has the effect of pulling it back towards the front, and away from the area that you are trying to shield..your face, which is then right back on the mask cushion! I wind up having to adjust it frequently during the night.When it’s where it needs to be, it does stop the annoying leaks that result in that horrible “farting” sound but, as I said, needs frequent readjustment during the night.Would I buy again? Not as these are constructed, No.it needs to have some kind of way to secure or make it with a smaller opening somehow.

If the liner stays in place reduces my air leakage quite a bit. however it slips the majority of the time, have tried several different ways to keep it in place, still no real results. Reached out to Snuggle & can't get a straight answer. Will continue my search for the right mask liner for my Fisher & Paykel Simplus Seal Mask (small).

Soft but needs to be about an inch wider. My daughter has a Siesta mask and it's not quite wide enough to cover all the way around it. She loves the purple color. The elastic is sturdy - very nice feature since it has to be able to withstand use by an adult with Down Syndrome.

I struggled with finding a good mask liner. My doctor recommended Remzzz mask liner but they kept pocking me in the eye and they were very uncomfortable. I found these mask liners that are washable and reusable. I can sleep at night without any problems and no itching problems. I even recommended them to my doctor for others who may be having problems with mask sealing. I am very happy with them and I am already using from my second order.
