The ReliOn RCM-832 humidifier uses AC-813 ReliOn filters. It is recommended that the filter be replaced once every two months or at the beginning of each season. The filter prevents unwanted minerals and bacteria found in water from becoming airborne. AC-813 filters are also compatible with the ReliOn RCM-832N.
The ReliOn RCM-832 Cool Moisture Humidifier should be disinfected before first use or following periods of storage. When filling the humidifier with water, the filter should be removed from the unit's base and soaked in a sink full of cool water. This helps reduce mineral buildup and increases the life of the filter. Without squeezing or wringing out the filter, return it to the base.
