I have this water filter in white and my mother in blue. Blue looks really good, and is something different to the same old white. Function is unsurpassed good. We have extremely hard water, so coffee machines like every month eineml the descaler want to ensure that coffee can also flow. Since my BRITA filter is there, I can let the descaler for espresso machine, coffee maker and kettle are the shelves safely. In addition, the water tastes a little better, just like a scalded coffee from the filter water. Price / performance = Buy, so that chemicals in the household has an end.
