The cleanable water chamber tub for the H4i™ heated humidifier is the container located in the front of your ResMed S8 series of CPAP or VPAP machines.
This cleanable model allows the user to easily remove the tub for a deep cleaning of any corrosive mineral build up.
It is recommended to use distilled water to avoid calcium and lime build up that may occur from the use of standard tap water. For best results you should change the water daily.
Please Note: The machine pictured next to the water chamber above includes the H4i Water Chamber Top Lid and Seal and is NOT included with this purchase.
