Crane Accessories, Replacement Demineralization Filter, Hello Kitty and Train Humidifiers

Helps reduce white dust, which is a byproduct of minerals caused by hard water. For best results, replace filter after every 30-40 fillings or every 1-2 months under normal use, or when the humidifier has not been operated for an extended period of time. To install, simply replace tank cap with filter and insert into full water tank. Place full water tank back on the water basin and wait fifteen minutes for the water to pass through the filter before starting the humidifier. Fits Crane Hello Kitty and Train Specialty Humidifiers.
