PearlCo Classic water filter cartridges optimize your tap water with hygienic filtration technology. The lime content of the water is significantly reduced, as is the amount of pollutants such as lead and other heavy metals. The same applies to chlorine, which affects taste, and many other substances that are undesirable in drinking water. The filtration produces aromatic, flavorful water that is often much better suited for preparing food and beverages than unfiltered tap water. The difference is particularly noticeable with tea and coffee: both beverages not only become visibly clearer but also taste significantly better! When preparing hot beverages, the advantages of lime reduction are particularly important: coffee machines, kettles, and similar electrical devices scale much less when using PearlCo-filtered water and therefore last longer.
