H4i Water Chamber for ResMed S8 Series

ResMed H4i Standard Water Chamber Tub

The H4i™ standard water chamber is used with the S8 series of CPAP and VPAP machines. For best results to maintain the ResMed S8 water chamber, it is recommended to use distilled water and rinse daily to prevent mineral build up. Long term use of tap water and not rinsing will result in corrosive build up on the water chamber plate. The H4i™ and H3i™ water chambers are different and can be identified by the model sticker on the front of the humidifier.

Important Product Note

The H3i™ Humidifier will require the original H3i Humidifier lid to work. You will need the H4i™ Lid to be able to use the H4i™ water chamber in your H3i™ Humidifier. Questions? Call our staff at  1-800-274-1366 for assistance.
