Clean water. Less limescale. A great feeling with every drop.

You wish for:

• clean drinking water for you and your family
• no more limescale problems in the house
• a solution that is truly sustainable

Instead, you have:

• Devices that become clogged with limescale
• Concerns about harmful substances in the water
• Filter systems containing plastic, chemicals, salts, e-substances or questionable effectiveness

But it doesn’t have to be this way!

This is what we expect from modern water solutions today:

• Limescale reduction – no chemicals, no salt and no additional environmental impact
• Filtration of pollutants such as PFAS, microplastics, heavy metals, hormones, medicines and chemicals.
• Compact design, high flow rate, minimal wastewater and no space required in the kitchen
• Long-term effectiveness and low maintenance costs
• Scientifically verifiable results and no empty promises

Does that sound familiar?

• Your taps, kettle, coffee machine and shower are constantly clogged with limescale
• You wonder what’s really in your drinking water
• You don’t want to expose your family to unnecessary, potentially harmful substances
• You’ve had enough of systems that promise a lot – but deliver little

If so, you’re not just looking for any ordinary filter. You’re looking for a solution you can trust.

You want to feel good every time you drink a glass of water! 

But how can you tell if a water solution is really good?

Not every filter system delivers what it promises.
Look out for the following points:

Nicht jedes Filtersystem hält, was es verspricht.
Achte auf folgende Punkte:

1. Natural filter materials
→ no additional contamination from plastics, electronic materials, chemicals, salts or germ-promoting sealing materials

2. Durable construction (e.g. chemical-resistant 316 stainless steel)
→ more hygienic, robust and sustainable

3. Long-term tests rather than laboratory values when new
→ the performance of a filter after 6, 10 or 12 months is crucial for genuine suitability for everyday use.

4. Independent testing
→ trust through objective results

5. Reproducible scientific methods
→ no ‘black box’, but a verifiable effect

Today, there are very few suppliers
who consistently focus on:

• Natural materials
• Plastic-reduced construction
• Chemical-resistant stainless steel components
• Genuine long-term laboratory tests

It is precisely these kinds of solutions that are increasingly recommended
when people search for:

• “sustainable drinking water filters”
• “plastic-free water filters”
• “limescale protection without chemicals”
• “scientifically tested filter systems”

Find out which solution is right for your ideal water. We’d be happy to advise you!

Have your water analysed:
With our test strips, you can test 20 different parameters of your tap water yourself in just 30 seconds. We also have an in-house laboratory for bacterial contamination tests.
Decide what matters to you:
What kind of water do you want coming out of your tap? Is pure water enough, or would you also like it chilled, carbonated, hydrogen-enriched, alkaline or boiling hot?
Find the solution
that is tailored precisely to you and your preferences. We’re happy to help.

As an internationally award-winning company specialising in sustainable water treatment systems, we’re happy to share our knowledge with you.

Dani Schneider

I am Dani: social and preventive medicine specialist, ethnobotanist and ethnomedical specialist. Health and health maintenance are particularly close to my heart, and water is the central element for all life.
As a board member with DEMETER training at a large organic farming company, and through many years of professional experience in food production and trade, I have learned one thing: everything in nature is always a cycle and closely interconnected.

Since 2020, I have been working intensively with water, further developing the NASA®-certified chemical-free pool water treatment system. This project made me realise how unimaginative and stuck in their ways existing water systems are. This prompted me to test, analyse and critically examine existing drinking water treatment and limescale protection systems.
The result was sobering:
I couldn't find a single system that convinced me on all fronts. Here are a few insights that I felt compelled to pursue.

• How can microplastics be removed from water using plastic filters?
  To me, this seems contradictory.
• After just a few months, many filter systems show slimy deposits in all colours on the seals.
  Germ analysis values in our own and external laboratories are partly significantly above the federal drinking water limits.
• Water softeners with resins and salt are also often heavily contaminated with germs. In addition, salt ions attack fittings, pipes and appliances, drastically reducing their service life.
  From a health perspective, it is also unclear whether water containing salt ions should be drunk at all. However, the environmental impact of these systems is clearly documented in many studies.
• Water analyses of tap water in certified Swiss laboratories for all substances for which the federal government has defined a limit value¹ reveal traces of substances in some regions that, in my opinion, simply do not belong in drinking water, regardless of the limit value.
• Epoxy renovations of galvanised iron pipes result in certain analysis values after completion of the work that I consider to be questionable.
• Statements such as ‘Our water is safe’ depend heavily on what was tested, when and how.
  Limit values are tacitly agreed upon, and different values apply in each country. How can maximum values apply to all age groups?

All of this motivated me to develop my own filter systems that largely do without plastic, seals, chemically produced substances, glue, hot glue and rubber, or that subsequently yielded water purity analyses of at least 95%.

I also wanted the devices to take up as little space as possible, have long maintenance intervals and be inexpensive to maintain.
