The Urspring in connection with a biofilter with Antical converts the lime in the water in such a way that it no longer precipitates in the pipes and water heaters, but is rinsed out with the drinking water. Limescale stains, just like the lime that accumulates in the kettle, can then be easily wiped off. At the same time, the Urspring removes all microorganisms from the water, so that the formation of biofilm in the water system in your house is greatly reduced. This can also be seen in the significantly reduced formation of biofilm with calcium deposits in toilets and toilet cisterns, on shower heads, but also in coffee machines and much more. In contrast to conventional water softeners, the Urspring Biofilter Antical does not replace the hardness component calcium with sodium, but leaves the calcium in the water.
