We previously had a water softening system and were dissatisfied with the water quality. After the exchange with a Mam Nature water dynamization, we are highly satisfied and now drink our water from the tap with great pleasure. Mam Nature filters and revitalizes the water and has also solved our limescale problem. The lime is now powdery and no longer settles. We are very satisfied and can recommend the Mam Nature solution.

Oliver HintermannInstalled: 7/1/2022 · Riedt-Neerach, Switzerland

We replaced our water softener system with a Mam Nature water treatment system because we were dissatisfied with the water quality. Double lime conversion, fine filtration and water revitalization transform our water from tap now in a very good water quality. We are very happy and now drink our new water with joy. The limescale problem has also been solved. The lime is now powdery and easy to wipe off and there are no more hard limescale deposits.

The water refining system is now in operation with us and I am very pleased with the new drinking experience! Wonderfully velvety soft water that I don't want to miss anymore, and my wife remembers the drinking feeling in Sri Lanka because of the earthy/loamy taste.

We have had the Mam Nature water treatment system since April 2023 and are very satisfied. When Mr. Hüppi did the water tasting with us, you could see the difference before and after the treatment. The treated water was much clearer and much gentler to drink. This system does what it promises.

As discussed with you, our message after the installation of the Mam Nature water refinement system. The installation was carried out successfully. After a few weeks with the new system, we can confirm that the water quality is excellent and we are very satisfied with it.

We are completely satisfied with the new Mam Nature water refinement system (after the water only flushed the pipes again for the first few days). The water is less calcareous, tastes finer / softer / better in the mouth and Diana, for example, feels a positive effect on the hands, which feel softer and used to be a little rougher.

We are very enthusiastic about the new Mam Nature water quality. The water is much fresher, gentler and makes you much more interested in drinking and showering. Angelica: My skin is less dry and therefore I need fewer skin creams. My afro hair was difficult to care for with the hard water. Now with the dynamized water, the care of my hair has become much easier and showering and washing my hair is much more fun.

It took a while, but a few days after the installation of the system, the quality of the water changed significantly. The water is softer and easier to drink. When compared with my still existing reverse osmosis system, the comparison is even more extreme. They didn't promise too much. In the meantime, I feel it is a waste to use the good water for rinsing. Thank you and greetings to Switzerland.

Taking care of our health and after a few years of reflection and research, we equipped ourselves with the Mam Nature system to purify and revitalize our water. We observed: the energy it has brought to our family, which set in at very short notice; the good taste of the water; the "lightness" of water, which allows us to drink more without realizing it; the softness of the skin when showering. We could also see that this water benefited our plants. For example, an old orchid that had survived for many months, without changing location or touching, just by watering with this new water, very quickly turned green at the roots, the leaves became thicker, and a nice surprise was that we had flowers that never stop blooming.

Independent Comparison

Every Water Treatment System — Compared

Tap water, bottled water, pitcher filters, reverse osmosis, softeners and UV purifiers — all measured against the criteria that matter for your health.

Reverse osmosis wastes 3–4 litres for every litre filtered. Softeners strip beneficial minerals. Mam Nature does neither.

The only system to simultaneously remove PFAS, retain minerals, protect against limescale, and cover the whole house — without salt or electricity.

Frequently Asked Questions

Quick answers to the most common questions about our water treatment solutions.

Our Swiss Water Cartridge, certified by ETH Zurich, removes PFAS (forever chemicals), heavy metals, BPA, pesticides, chlorine, drug residues, and more — at retention rates of up to 99.98% — while preserving essential minerals like calcium and magnesium.
Mam Nature offers several tiers to suit different budgets. From The Essential to the Complete Set Plus (which includes anti-limescale, particle filtration, contaminant removal, and water dynamization), there's a solution for every home. Visit our shop to see current pricing for your region.
Dynamized water is water treated using calibrated vortex flow technology that measurably reduces surface tension and increases dissolved oxygen content. Our Swiss Water Dynamizer uses a precision-engineered spiral flow chamber — no electricity, no chemicals, no maintenance — with a 10-year warranty.
Unlike salt-based softeners that remove beneficial calcium, Water LIME physically transforms limescale into a non-adhesive form. It uses zero salt, zero electricity, zero chemicals, produces zero waste, and requires zero maintenance — ever.
The Swiss Water Cartridge needs replacement once per year (or after 150m³). It's a simple 10-minute operation that requires no tools — the only maintenance your system needs.

Honest Questions Buyers Ask Before Ordering

The questions that actually block purchase, answered in plain language.

The amyloid hybrid filtration technology was developed at ETH Zürich and published in peer-reviewed Royal Society of Chemistry research (Bolisetty et al., 2020). Mam Nature engineers the housing and integrates the system; the filtration media is licensed from that university research. The same media is used in nuclear medicine departments to capture radioactive isotopes from hospital wastewater.
No. The system uses standard 1-inch threaded connectors (3/4" adapters in the box) and installs on the main water line after the meter — a routine job for any qualified plumber. Typical install time is 2–3 hours; expect a plumber bill of €200–350. We're currently building a vetted installer network in Switzerland and Germany — contact us if you'd like a recommendation in your region.
Wall space required: ~55 × 55 cm next to your incoming main water line, after the meter. Tools needed: standard plumbing kit + Ø12 mm masonry bit. The housing mounts directly on the pipe; the cartridge slides in. Detailed drawings, video walk-through, and a printable drilling template are linked from each PDP. Most installs are completed in a single visit.
The 10-year warranty covers manufacturing defects on the 316L stainless steel housing. The housing itself is built to last decades — there are no consumable parts inside it. After year 10, you simply continue replacing the annual cartridge as before. We've never seen a housing fail in normal residential use.
Cartridges are manufactured in-house at our Spinnereistrasse 16 facility in Rapperswil-Jona, Switzerland — not contract-manufactured. We carry forward stock and own the production line. If for any reason cartridge supply were ever interrupted, the housing accepts standard 20" Big Blue 4.5" filter cartridges (the industry-standard form factor), so you'd never be stranded without an option.
