Replacement water chamber for a ResMed H4i heated humidifier. Provides optimal performance for H4i humidification system.
This standard humidifier water chamber (with a frosted tub) will last for 6-12 months on average with proper care and maintenance. 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.
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.
