3-Layer Filtration System：The outer layer adsorbs impurities; the ion-exchange resin in the middle layer filters heavy minerals, such as calcium and magnesium ions; and the inner layer traps additional impurities before the water is released
Efficient Purification：The demineralization cartridge filters hard water, preventing the formation of scale and white dust for a more comfortable humidification experience; it also improves humidifier efficiency and extends humidifier life
Replacement Cycle：For a better experience, we recommend that you replace the mineral cartridge about once a month – a single cartridge can purify up to 40 gallons of water – depending on your water quality
