The design of the water filter is really great and very noble. The filtering the water to work properly, as usual of Brita filters. Also cleaning is without any problems. Criticism I have only, as well as already a previous speaker, with regard to the size of the container. The height does not bother me, the container fits fine on my faucet and tilted it is also never. But the real capacity does not correspond to the amount indicated. A filling not even enough to a standard kettle with 1.5 liter capacity to be filled completely, since a large part of the specified capacity is still in the water tank, and thus still unfiltered. Only when a corresponding amount has been poured (and these are just not even 1,5l) runs after the rest. Previously I had a plastic filter of Brita, which was still operated with the round cartridges. As a filling loose enough for the kettle. As a further drawback, I feel that the water flows not only from the chute when you tend the pot a little more, but runs out under the cover edge. In addition, then runs the yet unfiltered water that is left in the tank with out. Since I am very satisfied with the filters Brita ansich for years, I do not really regret the decision to buy. The device works and looks great, what was the main criterion for the purchase for me. With a few minor improvements, the evaluation would also failed perfect. So you have to refill more often and just pour carefully which are in practice just use deductions.
