Core S
Ultra-fine membrane post-filter for the Luna and Illumina models
Ultra-fine membrane post-filter for the Luna and Illumina models


The idea of placing the final filter stage directly at the water outlet is innovative and extremely hygienic. This is unique in this form and also very easy to use.


The ultra-fine hollow fiber membrane filter is an effective germ barrier and prevents unwanted contaminants from entering from the fresh water side.


This combination of water dispenser and ultra-fine filtration is exclusively available from The Local Water. This technology is integrated into the Luna and Illumina models.
In this special stainless steel fitting, the Core S ultra-fine filter is integrated directly into the aerator.
It acts as a reliable germ barrier, as the final filter stage is located directly at the water outlet of the fitting – in the form of an easily replaceable ultra-fine filter. A unique design. This filter must be replaced every 6 months. Our filter service will automatically remind you when it's time.


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.


Always have 1.5 liters of good water at hand. The beautiful jug made of high-quality glass automatically refills itself with fresh water after each use.
The water in the Illumina passes through the patented Core S ultra-fine filter. You can't get any more safety and protection against recontamination than that.
