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 (HumidAire) Heated Humidifiers as well as H3i (HumidAire) Heated Humidifiers that have been upgraded using the H4i Upgrade Kit.

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.

Needed a new lid, but had to purchase this compatible chamber
Written By: Bill, Santa Clara 7/21/2017
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.

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

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