The POU filter consists of all three filters that previously had to be installed separately. The fine filter prevents the penetration of impurities, rust particles, or sand; the activated carbon filter removes unpleasant odours, residues of substances such as chlorine or pesticides, and more from the water; and the capillary filter is effective against microorganisms and bacteria.

Despite its packed content, the filter has retained its compact small size and is easy to install directly at the point of use, ideally in the cabinet right under the sink. It is advisable to leave enough space underneath it to accommodate a bowl for the water that will flow from the filter during backwash. Thanks to the possibility of cleaning with backwash, the cartridge lasts much longer and does not need to be replaced again after a short time.
