This year Pack I have now already ordered the 2. because all other offers but are relatively expensive. I need my filter jug not only for drinking but also for the treatment of water for the production of tea, coffee and cappuccino. Therefore, the filter jug is several times a day in use. The limescale in pots, kettles and other equipment to be supplied with water is visible, because we have very calcareous tap water. So highly recommended!
