I have experience with table water filters other brands, because in Frankfurt the water is very calcareous and kinda weird tastes. Furthermore, forms when I with unfiltered water tea cooking as a funny movie on the tea. For this reason I use actually for all filtered water. The BWT table water filter is very easy to set up, to make it clean in lukewarm water and just place the new cartridge 5 minutes in cold water. Then plug it in and let go through 1x. This water discard. The nearest water is drinkable already! I'm very satisfied.
