This standard humidifier water chamber (with a frosted tub) will last for 6-months on average with proper care and maintance. It is compatible with all H4i Heated Humidifiers as well as HumidAire 3i (H3i) Heated Humidifiers that have been upgraded using the H4i Flip-Top Lid with Seal (Part 26953) or the H3i-to-H4i Upgrade Kit (Discontinued).

Usage Information: Each chamber will hold 390 ml of water (when properly filled to the fill line). Chambers should be filled with clean water each night. Using distilled water is not required, but it will maximize the life of the chamber and reduce mineral deposits. The metal heating plate on the bottom of the chamber should NOT be removed for cleaning.

  • Just What I Needed


    One of my old water chambers developed a leak. I have an older CPAP and was afraid I wouldn’t be able to find a replacement. I went ahead and got two just in case!

  • Aways a good experience


    My original water chamber (9 years) was still working, but I was pushing my luck with it, so I purchased a new one from cpapXchange to be on the safe side. I have purchased many items from this vendor and have always had a smooth experience. Prices are the same as everywhere else (I checked) and they even delivered it faster than expected from the NE USA. This is my go to place for cpap parts and supplies.

  • Water Chamber


    Product needed some shims to stop noise from air leaking. Once installed, everything is fine.

  • Poor construction


    The interlocking plastic that holds the heat exchange plate to upper body of the container fails within 8 to 12 months. This typically occurs without warning and results in the container leaking water.

  • Same tank as sold by local medical supplier but cheaper


    No difference between this tank and the tank sold by my local medical supply outfit, other than this one costs me far less. My last tank lasted several months before developing a leak for some reason.
