Crane Usa HS-1932 Animal-Shape Humidifier Filter - 2 Pack
Demineralization Filter Cartridge helps reduce white dust, which is a deposit of minerals caused by hard water. For best results replace filter after every 30-40 fillings under normal use or 1-2 months or when the humidifier has not been operated for an extended period of time. This filter cartridge works with Crane Frog, Penguin, Cow, Pig, Panda and Elephant Cool Mist Humidifiers.
