The Doulton DUC-1000 W9123053 UltraCarb is a four stage ceramic filter cartridge combining the highly efficient filtration properties of ceramic with the enhanced water treatment properties of activated carbon and the heavy metal reduction capabilities of ion exchange media. These elements have been made in accordance with NSF protocols for cyst, turbidity, particulate, and chlorine reductions (Class 1).

Fits in:
  • Twin Counter Top Systems: Doulton HCPS, HCS and HCP
  • Under Sink Systems: Doulton HIP, HIP2, HIP3 and HIS
  • Pressure Housings: AquaCera Inline (IP), HIS, HCP and HCS
  • Mountain Pure® Ceramic Filtration Systems MT660 and MT662
First Stage: The first stage consists of Doulton Ultracarb ceramic which provides genuine sub micron filtration. The cartridge reduces fine particulate matter, bacteria, cysts and turbidity.
Second Stage: The incorporation of silver locked within the ceramic structure gives enhanced bacteriostatic and self sterilizing properties.
Third Stage: An inner core of activated carbon block removes chlorine and organic compounds.
Fourth Stage: Ion exchange resin reduces lead and other heavy metals.
