The cleanable water chambers are compatible with all H5i™ Heated Humidifiers. They feature a removable top for easy cleaning and are top-rack dishwasher safe. 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.
