H4i Heated Humidifier Water Chamber Overview

The replacement Standard Water Chamber for ResMed's H4i Heated Humidifier used with the ResMed S8 should be replaced every 6 to 12 months to keep your CPAP equipment working like new. The Standard Water Chamber easily lifts up to be cleaned and refilled, and cannot be cleaned in the dishwasher.

The replacement Standard Water Chamber is the same chamber included with the H4i Heated Humidifier at the time of purchase.

This product only includes the water chamber.

What's Included:

  • 1 Replacement Humidifier Chamber

This product is the water chamber only and does not include the heated humidifier or any other parts or accessories.

Humidaire H3i Water Chambers are no longer available. H3i users can use a H4i chamber with their H3i Humidifier if the H4i™ Heated Humidifier Top Cover Lid and Seal is purchased. CPAP.com offers two upgrade kits which include this item as well as either a Standard or Dishwasher Safe chamber:

  • H4i™ Water Chamber Upgrade Kit for HumidAire 3i™ Heated Humidifiers
  • Dishwasher Safe H4i™ Water Chamber Upgrade Kit for HumidAire 3i™ Heated Humidifiers

    Maximum Fill Level Tips

    • Do not fill the water tank above the maximum fill line. Damage to the humidifier or therapy device may occur. If the water tank is overfilled, water may leak out of the tank inlet (located on the back of the tank) when installing the tank lid.
    • When disconnecting the hose from the tank outlet, be careful to ensure that the hose is not holding water. Water could travel through the hose and into the machine.
    • Use only room temperature distilled water in the tank. Do not put any chemicals or additives into the water. Possible airway irritation or damage to the water tank may result.
    • Remove the tank, empty all water, and replace the empty tank before transporting the humidifier base.
    • Do not attempt to fill the water tank while it is inside the humidifier.
    • To avoid spilling, do not disconnect the humidifier from the therapy device with water in the tank. Remove the water tank from the humidifier before disconnecting the therapy device.
    • Do not turn the humidifier on without the water tank installed. The Humidifier number setting must remain on 0 if there is no water in the water tank.
    • The humidifier door must be set in the open position before removing the water tank. Do not remove the water tank without making sure that the humidifier door locks into the open position.
    • Do not move the humidifier while the water tank has water in it.

    Please note: The manufacturer warranty is voided by water damage or misuse of the machine.
