These updated standard water chambers are compatible with all H5i Heated Humidifiers. They feature a removable top for easy cleaning. With regular care and maintenance standard water chambers will last up to 6-months on average.
Usage Information: H5i 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 "cleanable" chamber is available elsewhere on this site.
