Aquios RCFS220 Compatible Filter, KleenWater Brand KW2520CB Replacement Carbon Block Water Filter Cartridge, Chlorine Cloramine Sulfur Odor Pesticide Contaminants Dirt Sediment Filtration;

The KW2520CB-SlowPhos is a compatible replacement to the Aquios RCFS220. Aquios describes their filter as a softener which can fill the consumer with unrealistic high expectations that likely will be unfulfilled. A water softener operates on the principle of cation exchange which removes hardness cations and replaces them with sodium ions. Soft water is absent of dissolved mineral that cause harness i.e. calcium and magnesium. Our water filter does not soften the water but the Slow Phos polyphosphate does sequester the hardness cations thus inhibiting mineral scale formations and minimizing corrosion throughout the water system. Also the activated carbon content will adsorb chlorine and chemicals yielding very high quality water.

The cartridge dimension is 2.5" (W) X 20" (L) and is of carbon block construction. It will allow up to 5 gallons per minute flow rate and will remove chlorine for 7,000 gallons. This cartridge size can lead to restricted flow rates and reduced pressure. Removes dirt and sediment down to 5 microns.
