Refills For The Double Dome Well Water Filter System


SKU: 20112211WWR

1.5LB of KDF 55 and 1.5LB of KDF 85 Refill Cartridges.

This dual cartridge (double dome) drinking water filter uses a unique combination KDF® 55 1.5LB and KDF 85 1.5LB filters. KDF filters are high grade performance filters that removes oxidation agents (such as chloride), heavy metals (such as lead, copper, iron and hydrogen sulfide) and prohibits the growth of bacteria and algae in the cartridge.

This unit filters more than 600 contaminants from water, using a combination of trace minerals (copper and zinc in the patented form of KDF filters) and coconut shell carbon.
Water from countertop filters comes out of a spout connected at the faucet by an aerator (double diverter). This allows you to have filtered water or unfiltered water as needed.


  • Easy to install with complete instructions
  • Includes filter housing, chrome faucet diverter, twin filter cartridge set
  • Filters last 12 months/30,000 gallons
