Demineralize Humidified Air This is so important in keeping the powdered calcium off the floor, the furniture and the inside of my lungs !! needed the right product used when fireplace is in use. Defiantly needed. The cartridge is needed to keep the white dust from appearing. Good product to order on a regular basis the cartridge is one of the recommended demineralizers that I use nightly with the humidifier I purchased here. I feel that the waters quality and the mist emitted are much improved with the insertion of this product. I especially like the fact that once inserted it has a rather long life and does not have to constantly be replaced. There are several cartridges in a packet,and the price is reasonable. i would purchase again Product as described Ultrasonic Humidifier Demineralization C good product and nice price.
