Did the water filter now has 3.5 weeks in use and am fully satisfied. The water in us is very rich in lime. We bought the water filter to the water for baby bottles boil before to filter because my daughter to each vial (whether baby milk or tea) had extreme abdominal pain and all thought that that may come from the high calcium content in the water. The assumption was definitely right, because since then we filter boil the water before my daughter has no problems with stomach pains after drinking the vial. We use the water filters even for `water for the coffee machine (Senseo), for drinking, for tea, ... oh yeah: the vaporiser (steam steriliser for baby bottles), we use the filtered water, had the sterilizer since 3 weeks must only 1x (!) Descale, earlier I saw him after 2-3 uses descale! Kettle and coffee machine in the three weeks I've only 1 or 2 times to descale, before every 2-3 days.
The water is fill with the automatic filling opening is no problem, you just when you see that the upper container is full (and it shows definitely) turn off the water. If you leave the tap of course still on full blast it is clear that the water wegspritzt by the closing lid on the filling hole.
This morning (3,5 weeks after commissioning) the first time I've changed the Filterkatusche. In the period were approximately 75L filtered with Katusche (had to have with quoted when I got the water filter refilled to an overview How long does such a Filterkatusche, or how many liters you can now really Filter).
