Upgrade your HumidAire 3i Heated Humidifier (H3i) to the H4i®. Conversion kit (for HumidAire 3i docking stations: includes flip-top lid, seal and standard water chamber.
These Series 8 (S8) H4i® water chamber upgrade kits are designed to update and improve the older HumidAire 3i or H3i heated humidifier to use the newer and improved H4i® Heated Humidifier's water chamber design. Once the H4i Flip-top Lid is installed onto the H3i then the H4i® water chambers will work on both the H3i and H4i® humidifiers.
Our kits include either, the standard disposable or the cleanable water chamber and the H4i Flip-top Lid to convert H3i bodies into H4i®-style humidifiers.
The H4i humidifier has a larger chamber and heating plate to ensure humidification is optimal and available all night on one fill of the chamber.
