M Series Whisper Cap

Would not buy again

Great product!. I had used this before until the little plastic hinges on the back broke and I began literally attaching it to the machine with duct tape. BUT, it really does make the machine run quieter and my wife appreciates that.

My CPAP is much quieter now

Major difference on my M series machine. Cannot explain why there is such a wide range of review results. For the price worth the gamble. My wife is very pleased with my quiet machine.

I was amazed at how much this cap reduced the noise of my cpap. Well worth the cost.

No noticeable reduction in the noise level of the cpap machine. Useless.

I've been using my Remstar M series for over 4 years and thought I'd give this a try. I can definitely tell there is a reduction in noise but not enough to make me give it any more than 3 stars.

This is the second purchase for me with this one. Once having it then not having it you can really tell the difference.

It really cuts the noise down on the CPAP, not to nothing, but it almost sound like a small white-noise machine instead of bulldozer outside your window.

What an incredible difference. Its so quiet now I notice other sounds that annoy me... Like a mastiff snoring at the foot of the bed.

This reduced the noise factor to about half. It is worth the effort to get.

My previous whisper cap broke when I twisted it too tightly, though it did last several years. The whisper cap does keep down the noise on the apap.
