I live in Berlin and here the water is incredibly hard. the coffee tastes really ******* s. therefore I filter now sämtliches drinking and even the flower water to the filter. It also appears the flowers do well. a buddy said, would also all drugs residues that so swim in water, so that filter out 95%. I can nothing to say, so purely emotionally, the voices, the water also do better, it not only tastes better. one must note, however, that's the thing always wet and therefore forms bacteria. I store it in the fridge and cd to rule every month first the filter. Plastic parts from the unit coming into the dishwasher. so far I have found neither the smell nor the taste any bad odors that seem to be so ok. Of course you should not leave the water filled in the container, just like other water-well, that's clear. antibacterial filter is not, by disconnecting the water then boil it in doubt once again.
