Pre-filter set for ProfiLine osmosis 220 / 330 GPD
Pre-filter set for ProfiLine osmosis 220 / 330 GPD

Pre-filter set for ProfiLine 220 / 330 GPDStage 1: Sediment filter 1 micron Area of application: Sediment removal of sand, silt, rust and suspended matter (suspended solids) from drinking water. Properties: Ensures exceptional dirt holding capacity and low pressure losses Material: 100% pure polypropylene, without additives Filter material is therefore surfactant-free and contains no resin binders, lubricants, antistatic agents, release agents or other chemical additives. Stage 2: Activated carbon filter Area of application: Filtering particles from tap water Reduction of chlorine and other impurities such as organic compounds (VOCs) and dirt from tap water Reduces undesirable tastes and odours Material: Mixture of mixed activated carbon and special media Stage 3: Carbon block filter Area of application: Reduces the concentration of chlorine and organic compounds (VOCs) in tap water Counteracts bad taste and odour Properties: The high porosity of the carbon prevents the cartridge from clogging before its absorption capacity is exhausted, maximising the use of the carbon, while maintaining a low pressure drop. Improves drinking water quality through resin water softening process based on cation exchange. Material: Precise combination of mixed granular activated carbon (GAC) media mixed mild media of activated coconut, bituminous carbon and other advanced mixed filter media for effective water treatment

Bespoke Solutions

“The only limit is physics – everything else we can plan and build.”

We develop and handcraft all systems, making them individually customisable and extendable.

One key difference from many competitors: our filter modules can be replaced individually. The entire unit does not need to be replaced, only the component actually affected. This saves costs, reduces waste and extends the system’s service life.

In addition, our systems operate with significantly lower water loss (approx. 0.8 litres instead of around 5 litres) and are designed to be more sustainable overall.

Wasser ist nicht gleich Wasser

Wasser ist nicht gleich Wasser

Selbst in Deutschland variiert die Wasserqualität je nach Region erheblich. In manchen Gebieten ist das Wasser durch natürliche oder menschenverursachte Einflüsse mit verschiedenen Schadstoffen belastet, sei es in Form von Schwermetallen, Pestiziden, Medikamentenrückständen oder Mikroplastik. Herkömmliche Filteranlagen können diese unterschiedlichen Herausforderungen oft nicht effektiv bewältigen.

Pure water without compromise
Your key to health and wellbeing
 

What water would you like to drink every day?

Our bodies consist of around 70% water, and in children this can be as much as 80%. Water is the key to almost all vital processes in our bodies: from regulating body temperature to transporting important nutrients. You decide whether the water you drink every day is healthy and easy to digest. Choosing a high-quality, sustainable water filtration system is a conscious decision in favour of quality of life.

Clean drinking water cannot be taken for granted

The quality of tap water varies greatly, even within Germany, and it often contains pollutants that we cannot detect.

With our innovative technology, you can even eliminate pollutants and chemicals which, due to their small size and nature, can pass through osmosis membranes and enter your filtered drinking water.

Thanks to their flexibility, our water filtration systems can be specifically adapted to the issues affecting your tap water, for maximum purity and safety.

This means you can obtain the water you want at any time, at the touch of a button. Enjoy the difference.

Frequently asked questions

A reverse osmosis system forces tap water under pressure through an ultrafine membrane, removing up to 99% of dissolved substances – limescale, harmful substances, medication residues and microplastics.

Reverse osmosis filters at molecular level and uses some rinse water; microfiltration operates without electricity or wastewater and retains valuable minerals in the water.

Depending on water quality, pre-filters every 6–14 months; the membrane generally lasts 2–3 years.

Yes – our systems are designed for easy self-installation, with colour-coded connections and clear instructions. We will be happy to advise you personally.

Our systems achieve a unique wastewater ratio of up to 1:0.7 litres – significantly more economical than standard systems on the market.

Reines Osmosewasser ist mineralarm. Mit unserer Wasserveredelung (Oasis/Harmony) reichern Sie das Wasser auf Wunsch wieder mit Mineralien an.

A tree for every customer
Together for our forests

Forests are the heart of our planet. They provide us with clean air, store precious water and offer a habitat to countless living creatures.

In Germany, Austria and Switzerland, too, we face the challenge of preserving and sustainably strengthening our forests. This is not only about a stable climate, but also about the quality of life that forests give us. They are places of peace, inspiration and relaxation.

Climate change, storms and intensive use are taking their toll. That is why we plant a tree for every one of our customers. Together with you, we are helping to reforest our forests and preserve them for future generations.

With every tree, we give something back to nature – and to ourselves.
