Chlorine, pharmaceutical residues, hormones and microplastics – even in German drinking water. And it doesn't just affect your glass of water.
Chlorine, pharmaceutical residues, hormones and microplastics – even in German drinking water. And it doesn't just affect your glass of water.
German drinking water is safe – but not always optimal. A lot can happen on the way to your tap.
The water utility's responsibility ends at the house connection. The property owner is responsible for the pipes within the building.

Discover water filters nowEven if you exclusively drink mineral water: contaminants enter your body through other ways.
Your water is safe for all applications – without compromise.
Bacteria can survive at low temperatures. An invisible risk in your morning routine.
Germs go straight into your food. Absolute purity is the foundation of every meal.
Sensitive houseplants and edibles react to chlorine, lime and heavy metals. Pure water promotes healthy growth.
Maximum protection needed for a developing immune system. Zero tolerance for contamination.
Dogs, cats & co. drink from the bowl every day. Clean water free of germs and residues protects your four-legged family members too.
Water residue on dishes dries on along with everything it contains. Pure water, clean result.
Over 8 billion pills are taken annually in Germany. A significant portion of the active ingredients is excreted by the body and enters the water cycle via wastewater.
Pharmaceutical residues
Antibiotics, painkillers and blood pressure medications are not fully metabolized. The rest ends up in wastewater.
Hormonal contraception
The pill contains synthetic estrogens. These enter the water cycle via urine and are not completely removed by treatment plants.
Industrial chemicals
Plasticizers (like Bisphenol A) are endocrine disruptors and are increasingly found in groundwater.
The good news:
Activated carbon filters bind a large proportion of these organic compounds. Combined with UV-C disinfection, our systems provide comprehensive protection against these invisible contaminants.
Three coordinated solutions for different requirements – from the compact under-sink filter to the complete solution with UV-C LED disinfection and reverse osmosis.
Three ways to safe, hygienically clean drinking water straight from the tap – tailored to every need and household.
3-stage system combining pre-filtration, activated carbon adsorption and sterile filtration. Easy to install under the sink, low-maintenance and ready to use right away.
The 3-stage Home Edition system combined with UV-C LED disinfection. Eliminates up to 99.999% of all germs, viruses and bacteria – maintenance-free and chemical-free.
Reverse-osmosis system for the highest purity demands. Reliably removes nitrate, lime scale and the smallest minerals from your drinking water.
How the compact under-sink filter turns your tap water into purest drinking water – step by step.
Rust, sand and suspended solids from old house pipes are reliably retained by the 5 µm (0.005 mm) pore size.
Activated carbon block · 5 µm
Rust, sand and suspended solids from old house pipes are reliably retained by the 5 µm (0.005 mm) pore size.
Activated carbon from coconut shells (ACC matrix) binds chlorine, heavy metals, pesticides, hormones and organic pollutants – chemically and physically.

Mechanical membrane filtration with 0.1 µm pore size retains bacteria, fungi, yeasts and microplastics down to the absolute separation limit.
What the 3-stage system removes from your tap water – clearly at a glance.
Excerpt from the data sheets of the "Home Edition" water filter set.
3-stage filtration for hygienically pure drinking water directly from your tap.
The clever combination of activated carbon block and sterile filtration – for laboratory-quality drinking water. No more plastic bottles, easy installation under the sink.
Removes chlorine (99%), pesticides (97%), heavy metals like lead (95%), rust and suspended solids
Eliminates >99.9999% bacteria (e.g. Legionella, E. coli & Pseudomonas), microplastics, fungi and yeasts
High-quality activated carbon block from coconut shells with 5 µm pore size. Reliably filters macro contaminants like rust and suspended solids from your household pipes.
Mechanical membrane filtration with 0.1 µm separation limit. Important because activated carbon alone does not provide reliable protection against bacteria – they can even multiply there.
