✓[High Flow Rate and Long Service Life]This 20-inch water filter cartridge provides a large filtration area and high flow rate of up to 12 GPM. With a service life of up to 40,000 gallons, it saves you time and replacement costs. For optimum performance, we recommend changing the filter every 6-12 months based on your water conditions.
✓[MPP Sediment Filter]The MPP sediment pre-filter is made of premium polypropylene, which can withstand corrosion. It has a triple-layer design, and can effectively trap dirt, sand, silt, dust, rust, and scale particles as small as 5 microns.
✓[GAC & CTO Carbon Filter]The premium GAC water filter with highly adsorbent coconut shell carbon densely packed for optimal chlorine reduction with lower pressure loss. The 5-micron CTO carbon block filter cartridge follows to polish water by further absorbing tastes and odors, and fine particles for further finishing.
✓[Remember to Check the O-Ring Too!]We recommend inspecting and replacing the housing o-rings each time when changing filters to prevent leaks and optimize performance.
