The new and improved Franke 05 is a superb alternative to the Franke 02, Franke 01 or Franke 07, if your main concern is reducing limescale and the unpleasant scum that can form on the surface of hot drinks. The Franke 05 will also reduce chlorine to improve the taste and odour of the water and heavy metals such as lead.
The Franke 05 filter cartridge incorporates the latest carbon block technology combined with ion exchange hardness reduction resin. In addition to removing chlorine and lead the Franke 05 cartridge will also reduce the cosmetic effects associated with hard water, reducing limescale build up in the kettle and the film on the surface of hot drinks.
Water hardness varies greatly depending upon location and your Franke 05 filter cartridge will need to be replaced at 3 - 6 monthly intervals depending upon the hardness of your water and the amount you use.
