These chambers are compatible with all H5i Heated Humidifiers. Each chamber will hold 380 ml of water (when properly filled to the fill line). 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. A Long Life dishwasher-safe chamber is available elsewhere on this site.
