I've already bought my Brita filter for the second time. Unfortunately, the first fell off and the container is broken gone. At first I had doubts as to whether you need something. When it was my break, I've noticed that it has become indispensable. Since I filter my water so, I no longer have my tea cream teas. Also, I'd say they taste better. The filtered water, I fill in a decanter and store it in the refrigerator, although the container fits even in the refrigerator. Because I use the filter several times a day, he is with me always next to the kettle, which also did not have to be decalcified since then. Even pure filtered water tastes better to me than the normal tap water. In my area but the water is also very hard. For tea drinkers absolutely necessary!
