Great Purchase

I needed a new water chamber for my ResMed AirSense 10 CPAP machine and this was exactly like the original. My old water chamber had become yellowish and quite frankly well used after two years of use. The new chamber is exactly the same as my old one, when it was new that is, and I'm pleased with my purchase. Shipping was fast and I would order again from CPAP.com

Love it

This was a no-brainer because my water chamber had got a little funky despite my cleaning efforts. I can tell such a difference in my air quality after replacing the chamber. I will remember to wash in the dishwasher also. I had not done that before.

Great Deal

Excellent price on authentic water reservoir for PR System One CPAP machine. It is easy to clean and add distilled water. My only suggestion is that the manufacturer should make the fill line more visible.

Best Of The 3 Machines That I Have Owned

This is the third CPAP machine that I have owned. I bought it after the first one that I owned finally gave up the ghost. This machine is much much quieter than either of the other machines that I had - so quiet that I can't hear it most of the time. It also starts up as soon as I put my mask on - no more exaggerated breathing to turn it on. My other machines claimed that they would turn off if you took your mask off, but they never did. This one turns off in about 10 seconds. The machine also has a helpful report that tells you about the number of episodes you had overnight.

Delighted With My Purchase

I have an older model CPAP machine and when I need replacement items, such as a new water chamber, I have used CPAP.com because they always have what I need, at one quarter of the price of my local supplier, the transactions are easy and my parts arrive quickly.
