With a water filter from The Local Water, you'll always have plenty of good water in your home and automatically drink more! You'll never have to lug crates or return deposits again. You'll save tons of money, significantly reduce emissions, and support the preservation of a decentralized water supply.


Good water is also used for cooking. Undesirable substances such as pipe particle residues, hormones, or chemical compounds that cannot be boiled out will no longer contaminate your valuable food. If you have a good water filter, you should also cook your spaghetti in that water.


It is preferable to wash, rinse, or soak healthy vegetables, delicious salads, and protein-rich legumes with the high-quality water from your water filter. All harmful substances that do not enter your body relieve your immune system and facilitate detoxification processes.
The Core+ OS filter cartridge is used in all our reverse osmosis systems for effective pre-filtration and must be replaced every six months. This not only ensures the performance of the entire system but also protects the more expensive high-performance membranes. Adhering to these replacement cycles consistently significantly increases the service life of the membranes.




This prefilter is a special version of our Europe-wide renowned Core + activated carbon block filter. Not as fine and powerful, but still effective. It also serves as a sediment filter and filters out many pollutants and chemicals, especially chlorine, from the water. The high-quality activated carbon is obtained from coconut shells, as is usual for us.

Unsere Core+ hat ihren Ursprung in der Schale der Kokosnuss. Kokosnüsse sind Teil unserer Ernährung und Körperpflege. Statt Schalen-Abfälle wegzuschmeissen, kann man sie hervorragend zur Herstellung hochwertiger Aktivkohle nutzen. Mit einem speziellen patentierten Verfahren werden daraus in einem deutschen Familienbetrieb die Core+ Filterpatronen für The Local Water gefertigt.
