Research Products hydrol Hydrocore Water Panel Cartridge

Product Description

The RESEARCH PRODUCTS hydrol is a replacement water panel cartridge designed for the AprilAire 720 Series humidifier. It functions as an all-in-one, pre-assembled unit that pops in and out for straightforward annual maintenance. The cartridge absorbs water and allows it to evaporate into the airstream, maintaining indoor humidity levels during the heating season. The frame is constructed from recycled plastic, and the evaporator media incorporates aluminum, making the entire assembly recyclable at end of service life. Licensed HVAC technicians and experienced homeowners perform this swap as part of routine humidifier upkeep.

The hydrol cartridge fits the AprilAire 720A and 720M whole-home bypass humidifiers. These are flow-through evaporative humidifiers typically installed on the supply or return plenum of a forced-air gas or electric furnace system. The cartridge is sized at 16 inches high by 10.75 inches deep by 3.57 inches wide, matching the OEM cavity dimensions of the 720 Series cabinet. Annual replacement is recommended to prevent mineral scale buildup and maintain rated evaporative capacity. The unit arrives fully assembled with no field modifications required.

Installation Notes

Installation is performed by a licensed HVAC technician or a qualified service professional as part of annual humidifier maintenance. Before servicing, shut off power to the furnace and humidifier at the disconnect or breaker and close the humidifier water supply valve. The existing cartridge slides or unlatches out of the cabinet, and the replacement drops in without additional hardware. Verify the humidifier bypass damper and solenoid valve are functioning correctly while the cabinet is open.
