Filtration – Your path to the purest drinking water
Tap water in Germany is considered the most rigorously controlled foodstuff. Nevertheless, developments are increasingly emerging that fall outside the scope of existing regulations. Environmental pollution is now introducing substances into drinking water that we consciously choose not to consume – such as microplastics, pharmaceutical residues, and PFAS (persistent phenolic compounds). These long-lasting industrial chemicals are spreading globally, accumulating in soils, waterways, and human tissue, and can cause serious health problems. Even the plumbing system itself can contribute to contamination if rust particles, turbidity, or off-flavors from the pipes leach into the water.
We also face a future in which safe and healthy drinking water will become increasingly precious, expensive, and difficult to access – even here. Plastic pollution and the issue of PFAS will continue to worsen, while truly comprehensive solutions at the political and regulatory levels will take a great deal of time. Time we simply don't have. That's why it's better to take responsibility ourselves.
Check with your water supplier to find out exactly what kind of water you receive through your tap. Specifically ask about the levels of plastic and PFAS contamination and check the quality of your home's plumbing. If you determine that action is needed, we strongly recommend the viwa filter system .
With viwa , you bring your own spring water directly into your kitchen. Viwa filters, revitalizes, and mineralizes your tap water, transforming it into premium drinking water. Water you can not only taste, but also see and feel – clear, fresh, and full of life.

Why activated carbon filters?
Activated carbon is one of the most effective methods for water filtration. Unlike reverse osmosis, it does not remove all minerals from the water, but selectively filters out pollutants – while preserving valuable nutrients that our bodies need.
Retention capacity of viwa (tested in the laboratory):
- Drug residues: > 96%
- Free chlorine: > 98–99%
- Plant protection products: > 92–99%
- Microplastics: 99%
- Heavy metals: > 92%
- PFAS: 61.5 – 99.9%
- Sand/Rust: 99%
- Bacteria & germs: 99% (with sterile filter)

viwa is the first choice
The viwa drinking water filter transforms your tap water into an experience of purity, vibrancy, and taste. What remains is the essential – crystal-clear water, free from unwanted impurities – and what is added is the special touch: minerals, vitality, and a taste reminiscent of pristine springs.
In the first step, activated coconut carbon ensures that your water is freed from pollutants, turbidity, and taste-impairing substances. The result is impressive, with measurable performance: pharmaceutical residues are filtered out by over 96% , free chlorine by 98–99% , and pesticides by over 92–99% . Microplastics are almost completely removed ( 99%) , heavy metals are retained by over 92% , as are sand and rust (99% ). Even the particularly concerning PFAS ("perpetual chemicals") are reliably reduced by up to 99.9% by viwa. With the optional sterile filter, bacteria and germs are also removed by 99% – for peace of mind with every glass.
But viwa can do even more: With optional mineralization, your drinking water is enriched with valuable magnesium and zinc. This creates a slightly alkaline water with a pH value of 9 to 9.5 – pleasantly soft in taste and beneficial for the body. Zinc strengthens the immune system, while magnesium counteracts over-acidification. Together, these create water that not only refreshes but also noticeably benefits your health.
The transformation is completed by the revitalization unit. Here, the water is enlivened through vortexing and magnetization, regaining its natural energy. Crystal analyses show that viwa water forms structures that are virtually indistinguishable from original spring water. A difference you can not only see, but feel with every sip.
With viwa, you bring a piece of mountain spring water into your home – premium drinking water straight from your tap. Clear, vibrant, and full of energy.

Comprehensive advice from your water sommelier
I not only support you with my products, but also with expert advice in the field of water filtration. For example, as part of the PFAS expert forum of the Rastatt municipal utilities, I tasted, evaluated and compared the freshly drawn Rastatt drinking water – with excellent results.
If you are interested in a personal water quality assessment or a customized filtration solution for your home, business, or community, please feel free to contact me. I will work with you to analyze existing contaminants, determine appropriate measures, and show you how the right filtration system can help you achieve maximum quality and safety.
"Tastes like spring water. We didn't expect the improvement to be so significant. For the first time, tap water actually tastes really good. The filter also seems high-quality and isn't some flimsy, rickety thing. Highly recommended :)"
“ A noticeable difference in taste! We live in an old building and the water previously tasted metallic. Now it tastes much fresher and somehow softer. We are thrilled!”
