Frequently Asked Questions

This OEM water chamber provides reliable humidification for CPAP machines and "fits perfectly." Customers said the dishwasher-safe version is "great" and easier to clean. Some noted the chamber capacity is small and can "dry out" in cold weather or require daily refilling. Praised for quality, reasonable pricing, and no leaks.

Nice replacement

A good, named brand replacement for the chamber that comes with your AirSense 11. I bought it so that when I clean my equipment I have another water chamber to pop in and can let the washed one dry for a few days.

Fast Delivery

I got the chamber right away. The staff is super helpful.

Good chamber for a good machine

This is a very good humidifier chamber for this machine. I'm hoping for some more durability from the machine washable version of it than the hand washable one.

Great upgrade

I upgraded to the cleanable water chamber and I love it. It's sturdy and I can put it in the dishwasher and get it super clean.

Chamber is perfectly sized for warm weather but runs dry in cold weather

I use my ResMed | HumidAir Water Chamber in an AirSense 11 Sutoset CPAP, along with distilled water and a heated hose. The chamber is perfectly sized to humidify my sleep sessions when the climate is warm, but it runs dry after about 5 or 6 hours when the climate is cold. I wish Resmed would create a higher-capacity water chamber.

It is hard to clean with all the different shapes inside

Finally!

I've been laid off and was trying to save money buying a cheaper water tank. It leaked really bad. I saved up and purchased the ResMed water chamber. Not one leak. I guess the saying "you get what you pay for" is applicable here. :-)

Water Chamber - AirSense 11

Could be larger to accept mort water - easy to dry out
Very difficult to wash - it would be better if the lid is detachable

great stuff

It fits perfectly and doesn't crack like the others Ive bought.

Perfect

I happen to come upon a great deal on this water chamber. It’s EXACTLY like the original one that came with my machine. I figured I will use each chamber for four days and wash everything together once a week.
Besides my old one was getting a little finicky. A few times I had to pull it out and push it back in to get it to seal.
Got it on sale and the price was right.

Works well

I needed a second chamber in the cleaning rotation. Works great
