A filter with this property can remove or significantly reduce the chlorine content in water. Chlorine is commonly used for disinfecting drinking water in the water supply network, where it ensures its health safety. However, for coffee preparation, its presence can be undesirable, as it negatively affects the coffee's resulting taste and aroma. Coffee prepared from chlorinated water may have an unpleasant chemical aftertaste. Filters for chlorine removal most often use activated carbon, which is a porous material that effectively binds chlorine and other organic impurities. As a result, the filtered water is taste-neutral and allows the natural flavor of the coffee used to fully emerge.
