Product Details
✓Compatible Models：Our demineralization cartridge is only compatible with the Dreo humidifier models HM306, HM311/311S, HM524/524S
✓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
✓Buy with Confidence：Our products are made of high quality materials, so I have confidence in our products and you can buy with confidence. Package includes 6 filter cartridges
