With the Brita Fill & Enjoy Marella XL you always have filtered drinking water at home. 2 liters of water is what you drink daily, so you have fresh filtered water every day. The jug filters 2 liters of tap water in one go. Filtered water is not only used for drinking, but is also used in household appliances such as an iron. As a result, descaling is no longer necessary. You keep the jug with the filtered water in the door of the fridge, so it stays nice and cold. The electronic memo gives you a reminder so that you know exactly when you are replacing the filter cartridge.Please note: only the Brita Filter cartridges Maxtra+ fit in this Brita Fill & Enjoy Marella XL.
