A potentially good idea! In principle the "idea" was great until I attempted to fit over mask...but it kept slipping off..so should it be made of a more "bandage quality" material , impregnated with a "grippy edge" , so that it stays on the mask and protects your face.As it stands I found it costly and ineffective...try again "Snugz mask liners"

It is soft and feels great against the skin, I have a nasal mask, but I have not been able to use it as an hour or two into sleeping it becomes very noisy and the sound wakes me and my husband. The cover would be better if it was about an inch longer so it could then fit on my mask the way it is supposed to. At the current length I cannot get it to tuck over the way it should.

Better fit Gave this product a long use of several months before I made up my mind. This product helped my mask fit better over the bridge of my nose and keep the top of the mask from pushing into the tear ducts of my eyes making it more effective and more comfortable fit.

Sure makes the mask more comfortable… Sure makes the mask more comfortable and no leakage! Was having so much trouble with leakage around my eyes! Just had cataract surgery and was very irritated. This solved the problem completely.
