Our built-in filter systems are all made in Germany and tested for a service life of over 50 years. They are guaranteed free of harmful substances such as PFAS, formaldehyde, and bisphenol A (BPA).
Thanks to internationally recognized medical approvals (FDA, USP Class VI, and ISO 10993-5 / -10 / -11), we offer maximum safety—for your health, everyday life, and home.

With nearly 40 years of experience in water treatment and as a long-standing testing laboratory for international filter manufacturers, our products stand for the highest quality. Not only doctors and alternative practitioners rely on them, but also renowned partners such as Bionade, Chantre, and Charité Berlin.

Our water filters are created using a patented process that combines state-of-the-art technology with genuine craftsmanship—for quality that sets standards worldwide.

We show what goes into our products—from the materials to the manufacturing process. Anyone who wants to can even visit our factory and see for themselves.

Anyone can easily install our filter systems themselves. No special tools are required. If necessary, we also provide our customers with free support via video conference or with technicians on site.

The Local Water is owner-managed, cooperatively organized, and completely debt-free.
Our financing from pure cash flow makes us independent in the long term and commits us to a single goal: quality without compromise.

Our products are sold directly from the workbench to the customer. This has the advantage that the customer receives high-value products at very attractive conditions, as there are no large sales structures to serve.

The Local Water is a German brand product with the highest quality standards. These filters are also in high demand internationally and are already in use on every continent except Australia. That is why, since 2025, we have also been active locally with a branch in Indonesia, a rapidly growing country popular with many expats, and a location in England will also be opened this year. Further countries are in the pipeline.

Als Manufaktur realisieren wir auch individuelle Sonderanforderungen und fertigen Lösungen nach Maß. Von der kompletten Hausanlage bis hin zu Sonderanpassungen an den bestehenden Produktserien in Bezug auf Aufstellort oder Leistungserweiterungen. 

Als echter Hersteller beschäftigen wir nicht nur namhafte Verfahrenstechniker, sondern betreiben schon seit Jahrzehnten Forschung und Entwicklung im Bereich Wasseraufbereitung. Das im Unternehmen gebundene und in der Form einzigartige Know-how ermöglicht die Herstellung besonders sicherer Produkte.

Die von uns angebotenen Wasserfiltern sind immer nachhaltiger als jedes Flaschenwasser. Doch zusätzlich zu diesen Vorteilen, optimieren wir unsere Herstellungsprozesse ständig und setzen auf natürliche Rohstoffe wo wir können ( z.B. Bio-Kunststoffe)

Reine Aktivkohle-Blockfilter und Umkehrosmose sind zu Recht die marktbeherrschenden Filtertechnologien. Wir bieten für beide Varianten langzeiterprobte Produkte in Premiumqualität, gefertigt in unseren Manufakturen in Deutschland.
