Specially chosen by the experts at Doulton®, our limescale water filter can be installed ahead of the ceramic water filter cartridge to reduce the build-up in your water. As well as protecting your appliances, this water filter for limescale removes its characteristic chalky taste – so is ideal for use in hardwater areas.
