ResMed Standard Water Chamber for H4i™ Heated Humidifiers

4.86 Average Rating of 14 Reviews Read Reviews



USAGE: Each standard water 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.

COMPATIBILITY: This chamber is compatible with all H4i Heated Humidifiers. It is also compatible with HumidAire 3i (H3i) Humidifiers that have been upgraded with the H4i Upgrade Kit. If your HumidAire 3i has not been upgraded; then your 3i Flip Top Lid will need to be replaced with an H4i Flip-Top Lid (Part 26953) prior to using this chamber.

  • Thank Goodness

    While on vacation my water chamber of many years fell apart. I went online and ordered a new one from Direct Home Medicsl and it was waiting for me when I got home. It fit perfectly and works great!

  • Perfect fit. Great price. Arrived quickly.

    Quicker and easier than going through the insurance company and medical supplier.

  • Needed a new lid, but had to purchase this compatible chamber

    At first I was a bit upset about needing to purchase this chamber just because I needed a new lid for the humidifier. But I really like the way this one is made better than my older H3i chamber. Glad I bought it.

  • Great price

    Very happy with DHM's pricing and shipping of this. Product itself is good but slightly difficult to clean after some time.

  • I like the new replacement

    I have a Resmed 3i that I had to convert to accept the 4i tank. It works like a charm.

    I am so happy that I found this company. I get the same quality product for much less. The one company that I used to get my supplies from won't even sell these to me as they claim they don't get enough money from insurance--so customers are on their own to find them.
