iSpring FKG15Q Quick-Change Inline KDF/Carbon Filter for Under Sink Water Filter System

The CU-A4 3rd Stage filter cartridge features KDF (Kinetic Degradation Fluxion) media combined with activated carbon. KDF is known to effectively remove a variety of contaminants, including unpleasant taste and odor, hydrogen sulfide, iron, lead, nickel, chromium, cadmium, calcium, aluminum, mercury, arsenic, and other organic compounds. When used in conjunction with carbon, the KDF media can extend the carbon filter's lifespan by up to 8 times. Additionally, the filter adds a healthy dose of zinc ions to the filtered water.

To ensure optimal freshness, the filter cartridges are individually wrapped. The 1/4" Quick-Change connections allow for easy and convenient filter replacement. The CU-A4 3rd Stage filter is compatible with the iSpring under sink ultra filtration system models RE4T and RE5T, as well as the CU-A4 and CU-A3 models.
