Homedics Demineralization Cartridge, 4-Pack, Ultrasonic Humidifiers Brush -6mm (1/4)Hard water is the reason an ultrasonic humidifier coats a bedside table in white powder. The misting plate cannot tell water from the calcium and lime dissolved in it, so everything goes into the air together. Dropping one of these into the tank filters the minerals out before that happens. Each cartridge is good for roughly 30 to 40 full tanks depending on how hard your water is, and the pack of four covers most of a winter. Made for Homedics
