2 Pack Enhanced Comfort Replacement Water Chambers for AirSense 11 and AirCurve 11 FSA or HSA Eligible Water Tanks Heated Humidifiers Replacement CPAP Supplies

This unit sadly doesn’t work properly. It is not hinged and uses a clip on type lid that apparently impedes functionality. The chamber leaks during usage which could cause other issues like mold inside the unit. I thought at first it was a defect in the first of the two units received. It was not. It is a horrible design flaw. I hate saying this but I would give ZERO STARS if I could. ☹️

What a vale. Matched my cpap machine (Resmed 11) perfectly and cheaper than the cpap websites. Seals great !

For some reason, this manufacturer decided that instead of functional hinges, these reservoirs needed a simple hook clasp that is both hard to get together and comes off completely every time you open it. The components are also only spot welded together (or whatever the term is when it's plastic), instead of fully sealed, so every time you turn it on, a lake forms under the machine. At least it seals to the airflow, so it's got that going for it... Overall, I am severely unimpressed. I guess this is a "you get what you pay for" scenario. These are the cheapest on here, and they function like it.

Junk. Low capacity seal leaks all the way around doesn't hinge it's two separate pieces heat plate leaks water in multiple spots complete garbage.

They work well! You most definitely need to be careful with the lid there not hinged so it takes a minute to get it to close right w/o breaking the tabs.

Pieces come completely apart to fill and not easy to put back together. Decent for the price , but overall not great. Fits in machine perfect and does the job.

I so wanted this to work, but it wasn’t meant to be apparently. It was hard to get to the max water line as I had to raise the lower to make it level. The non-hinged design is great for cleaning only. It fits great, but is the only positive. I woke up to water everywhere including the machine itself. I am glad that I have a tray dedicated to the CPAP. I am more that sure that I got zero humidity as the water leakage was equivalent to what I use nightly. Great idea with terrible execution. I should have read the reviews before purchase.

I used one of the water chambers of 2 weeks and it started to leak. I looked it over and don't see why its leaking, but it is frustrating when I had to use the second water chamber so quickly. This is a very poor product if it starts to leak after only a couple of weeks.
