These liners have adhesive so that they stay on the mask. You can use them for a week or more before replacing. The advertisement says a full months worth--and that means only 4 liners. So, you wind up paying the same amount for 4 of these that you do for 30 of the ones without adhesive. They are overpriced, in my opinion. $25 for 4 liners? Should be $10 at the most.

I bought these upon the recommendation of my doctor, to reduce leaking from my mask. I was having trouble with air leaking into my eyes, making it very uncomforatble. Well, the mask didn't get rid of the leak, but it does muffle and redirect it a bit. The result is that I can use my mask - it isn't pouring air into my eyes anymore - it's leaking where it is less annoying. The leak level is within tolerance, so this product was successful in that it enables me to use my mas.

I have used every type of Cpap or Bi-Pap Machine And having a beard you know how hard it is to have a seal from the mask to your face when you have high pressure. Other sealers can't compete and do what the RemZzz's can do.

Made of t-shirt cotton, these liners really helped keep me comfortable during hot flashes at night! Before, my mask would exacerbate the wet feeling, now, I’m cooler and dryer. So glad to find these.

It keeps the plastic, from the bipap face mask, off of my skin. I'm on a fixed income so I am able to wash them and use them more than once. They are expensive and not covered by insurance.
