ProTec Demineralization Cartridge
This demineralization cartridge fits Honeywell Ultrasonic humidifier model V-5100 and helps reduce white dust, which is a deposit of minerals caused by use of hard water. There is 1 cartridge per package and for best results, replace as necessary (every one to two months, or 30 to 40 fillings under normal use) or when the humidifier has not been run for an extended period of time, and clean the humidifier as described in the Use and Care Manual.
