Service frequency may vary depending in local water conditions. High sediment, chlorine, turbidity, or hardness levels may require more frequent service. The integrated 3-in-1 filter cartridge combines high-efficiency filtration and reverse osmosis technology to remove up to 99% of contaminants, including chlorine, lead, heavy metals, pesticides, fluoride, and more, ensuring clean and safe drinking water.
