After ten days, the display above the lid still showed quite 50% filtering capacity, then came the disillusionment. Within a short time my calcified kettle and there were even little black particles of activated carbon filter recognizable. The water had on the surface streaks disgusting than ever. To prepare baby food this water quality is absolutely no longer usable. We have to filter including pot scrapped immediately.
I feel admittedly pretty verschaukelt from what Brita offering there. In my opinion, the filling volume of the pot is simply too big for the standard Maxtra filter cartridge and this "counting" the top of the lid is completely for naught, because it understands the individual consumption yes in any way. I guess once I had eight days to install a new filter cartridge, no matter what the useless display shows the top of the lid. However, at this price I can buy three times as much bottled water.
Leaving aside my negative experiences the XL size has a crucial disadvantage: they fit into any refrigerator door into it. While this may for water, which is to be followed anyway heated in the kettle or in the coffee machine is not so important at first, but one should bear in mind here is that, like other container with food, and the water filter is not in sunlight or on a particularly warm place should be placed, since in this case nuclei are produced, and could add up quickly. So get perhaps you prefer opt for the smaller version of Marella, which can be easily stored in the fridge.
