- Designed to reduce chlorine taste and odor and utilizes a natural, polyphosphate additive known as Siliphos to soften and condition your water.
- Protects hot water system corrosion and maintains energy efficiency
- 2.5 x 20 Inch, Made of Carbon Block Construction
- KW2520CB-SlowPhos is also an ideal filtration selection for commercial ice machines and commercial coffee makers

The KW2520CB-SlowPhos is a compatible replacement to the Aquios RCFS220 filter. 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.
