Too bad that I have found this alternative not sooner. The expensive BRITA water filter I saving my future. I have found no weaker effect - what the Kalkfilterung terms - rather even better but as I have no possibility to measure and this is my only subjectively, this statement is not now binding ;-) The last BRITA filter that I had had, even if the water has a strange aftertaste, which my jasmine no longer tasted - only in this way I looked for alternatives and found it here. Am satisfied. Even my water and I refer in the east of Munich (Zorneding), so not very good but the lime water Munich forth like this, if that's helpful for someone to mention it.
