The Doulton Cleansoft Reduction Cartridge is made in Britain by Doulton. This ceramic filter element protects against the damaging effects of hard water by using the Doulton CleanSoft limescale reduction cartridge in the first chamber of the DUO drinking water filter. This will reduce temporary hardness in drinking water, reduce limescale build-up in your appliances and prevent an unpleasant film forming on the surface of tea. It is an effective, WRAS approved, limescale water filter containing a highly effective ion exchange media to also help reduce the unpleasant chalky taste often experienced with hard water.

The Doulton Cleansoft Limescale Reduction Cartridge is suitable for the following models:

  • Doulton HCP Duo
  • Doulton HIP Duo
