Frequently Asked Questions

Mam Nature Swiss uses a patented protein-fiber adsorption technology, laboratory confirmed by ETH Zurich University. Unlike conventional filters, our system retains PFAS at >96–>98.5% and heavy metals at up to 99.98%, while also reducing pesticides and preserving essential minerals like calcium and magnesium. This means you get pure water that is still healthy and mineral-rich. On top, as the final treatment stage (in the Complete Set & Complete Set Plus), our Swiss Water Dynamizer changes the molecular structure by extreme turbulation & frequency transmission.

Yes. Our filtration performance has been independently laboratory confirmed by ETH Zurich University, one of the world's leading technical universities. The retention rates are documented in our scientific Filtration Performance Report. Additionally, our systems are manufactured under ISO 13485 quality management standards and hold Swiss Safety Center certification.

Independent laboratory evidence includes the ETH Zurich University Filtration Performance Report. Certifications include the Swiss Safety Center Pressure Test Certificate and ISO 13485 Quality Management Certificate. All documents are available on our Reports & Certifications page.

Yes. Mam Nature Swiss AG is a Swiss company located in CH-8645 Jona / Switzerland, and all our products are engineered and manufactured in Switzerland. Swiss precision engineering ensures the highest quality and durability.

Dynamized water (also called structured or revitalized water) refers to water treated using calibrated vortex flow technology. Our Swiss Water Dynamizer uses a precision-engineered spiral chamber that measurably reduces water surface tension and increases dissolved oxygen content. In nature, high-quality spring water flows in continuous vortex motion — the Dynamizer replicates this natural movement. No chemicals, no electricity.

The Dynamizer uses a precision-engineered spiral flow chamber to create a natural vortex effect. This has a quintuple action: (1) it restores natural water movement and dissolved oxygen balance, (2) it distributes minerals more evenly throughout the water, (3) it maintains these improved properties long-term, (4) it transmits a natural frequency set (from lava power) to the water, and (5) it protects the water from radiation employing an intelligent layer technology. It's a purely physical process — no chemicals, no electricity.

Yes. The following scientific studies showed scientific evidence of dynamized water:

1. Dynamized Water examined by the GDV Method: "Experimental data in a double-blind experiment over 3 months demonstrated a statistically significant effect of using dynamized water on the energy state of a group of people compared with a control group."

2. Dynamized Water examined by the Bioscope System: "Significantly improved electrical quality of dynamized water: an increase in the electrical signal flux (average spectral phase) indicates that the water carries an increased electrical potential (greater electronegativity). This has a positive impact on the growth and state of any living species."

3. Dynamized Water examined by the MicrotoxO Method: "Usual tap water compared with dynamized water exposed to pathogenic germs clearly showed that dynamized water inhibits the growth of pathogenic germs (E. coli) compared with untreated tap water."

4. Effects of Dynamized Water in the in-vitro multiplication of banana plants: explants placed in the structured (dynamized) water medium showed differences in morphogenetic responses compared to explants in the conventional medium. An improvement was evidenced for each parameter studied — most notably in shoot emission and weight gain — placing structured-water treatments above conventional ones.

5. Water-crystal photographs of untreated & dynamized water: due to its long path through straight water pipes, normal untreated tap water loses its capability to form regular, hexagonal water crystals. After being dynamized, the same tap water regains its capability to form beautiful hexagonal water crystals.

6. Biological stability of dynamized water: dynamized water shows extreme biological stability. In the present sample, dynamized water kept in a transparent glass bottle exposed to normal daylight showed not the least sign of algae or organic degeneration over an observation period of more than 16 years.

7. Partial integration of oxygen in dynamized water: the dynamized-oxygen water showed a capacity for partial linking-in of oxygen in water. This had never been measured previously. The difference compared to other oxygen waters is highly significant and reproducible at any time.

8. Flushing out of 25 heavy metals in urine by dynamized water: the study showed a remarkable reduction of heavy metals with dynamized water — by over 50% within about 1 year — in a test person over 50 years old.

9. Electroluminescence and germination with dynamized water: the electroluminescence test and the germination test show a significant trend indicating that treatment of the water leads to different results. The germination test suggests the influence of treatment is positive.

10. Strong reduction of uranium in water having passed a water-dynamization device: reduction of uranium concentration in water from 7.8 and 7.2 µg/litre to 0.006 µg/litre — a reduction of over 99%.

Important comment: there was no application of any kind of filtration or other manipulation to retain any substance in the examined water-dynamization device.

No. The Swiss Water Dynamizer has zero moving parts, requires no electricity, no cartridges, and absolutely no maintenance. It is built from highest-quality materials with a 10-year manufacturer warranty and unlimited capacity at a water volume of 5,000 liters/hour.

Our Swiss Water Cartridge retains PFAS (PFOA, PFOS, PFBA and more) at >96–>98.5% and heavy metals (lead, cadmium, arsenic, chromium, copper, manganese) at up to 99.98%, while also reducing pesticides, chlorine, pharmaceutical residues, BPA, aluminium, and radioactive substances. This is laboratory confirmed by ETH Zurich University and documented in our scientific performance report.

PFAS (Per- and Polyfluoroalkyl Substances) are synthetic chemicals known as "forever chemicals" because they don't break down in the environment or the human body. They are found in tap water across Europe and have been linked to cancer, immune system damage, and hormonal disruption. Our filtration system removes PFAS at rates of >96% to >98.5%, laboratory confirmed by ETH Zurich University.

No — this is a key advantage of our protein-fiber adsorption technology. Unlike reverse osmosis systems that strip everything from water, our cartridge selectively targets harmful contaminants while preserving essential minerals (calcium, magnesium, potassium) that your body needs. You get pure water that is still naturally mineral-rich.

The Swiss Water Cartridge should be replaced once per year (or after 150m³ of water). The replacement process takes approximately 10 minutes and requires no tools. This is the only maintenance your system needs.

Rated flow is up to 2,000 liters per hour — among the highest in the industry. Independent testing documented application flow above 1,800 L/h under the test conditions documented in the ETH report. This means nearly zero pressure loss and instant access to filtered water from every tap in your house, even when multiple taps are running simultaneously.

The Water LIME doesn't remove calcium from water — it physically transforms limescale's crystal structure. Using powerful permanent magnets, it converts scaling Calcite into non-adhesive Aragonite. This means much less limescale deposits on pipes, appliances, or surfaces, while all the beneficial calcium minerals remain in your water.

Traditional salt-based softeners remove calcium entirely (which your body needs), use salt and chemicals, consume electricity, waste water, and require regular maintenance. Water LIME uses zero salt, zero electricity, zero chemicals, produces zero waste, and requires zero maintenance — ever. It's a 100% physical, one-time installation.

Absolutely not. Water LIME has no consumables, no moving parts, no electricity requirements, and requires zero maintenance once installed. It comes with a 10-year manufacturer warranty and is designed to last without any upkeep.

No. Since Water LIME works by physically transforming limescale structure rather than removing minerals, it preserves the natural taste and mineral content of your water. Many users report that their water actually tastes better because the restructured minerals are more evenly distributed.

Mam Nature systems range from €1,090 for The Essential to €3,598 for the Complete Set Plus (EU pricing; other regions shown in the shop). The only recurring cost is the €240 Swiss Water Cartridge, replaced about once a year. Installation is a 2–3 hour job for a qualified plumber — ask for a fixed quote, as rates vary by region. Use our savings calculator to see how much you save vs. bottled water.

The Complete Set Plus includes 4 integrated components: (1) Water LIME — anti-limescale protection, (2) Particle Filter — removes sediments, with automatic backwash included, (3) Fine Filter with Swiss Water Cartridge — retains PFAS at >96–>98.5% and heavy metals at up to 99.98%, while also reducing pesticides, and (4) Swiss Water Dynamizer — restores natural water structure. Together, they deliver pure, soft, and revitalized water from every tap.

Professional installation by a qualified plumber is recommended for all whole-house systems. The installation is straightforward thanks to our compact, modular design and 360° connectors. Most installations are completed in 2–3 hours. We provide detailed installation guides and our support team is available to assist.

The only maintenance is replacing the Swiss Water Cartridge once per year (or every 150m³) — a 10-minute, no-tools-required operation. The Water LIME is maintenance-free for life, the Particle Filter backwashes itself automatically once or twice a year, and the Dynamizer requires zero maintenance. Our systems are designed for minimal upkeep.

While our systems are designed for simplicity, we recommend — also to ensure continued coverage from your water-damage insurance — professional installation by a qualified plumber for whole-house systems (Essential, Essential Plus, Complete Set, Complete Set Plus). This ensures proper integration with your home's water supply. The Swiss Water Cartridge replacement, however, is a simple DIY operation requiring no tools. For clients who prefer a replacement service done by a professional, we offer such in selected markets — or you simply ask your sanitary installer.

The modular design, compact housing, flat sealing connectors and a borehole plan streamline the process. We provide comprehensive installation guides with each system. However, each installation situation is different and has to be evaluated by the executing sanitary installer.

Our components are built to last: the Water LIME and Dynamizer come with a 10-year warranty, the system housing is made from 316L stainless steel, and the only consumable is the Swiss Water Cartridge (replaced annually).

The system is installed on your main water supply line, typically near the point of entry right after the water meter (basement, utility room, or garage). This ensures every tap, shower, and appliance in your home receives treated water. The compact design requires minimal space of about 66 × 83 cm.

We ship to Switzerland, Europe, Morocco and worldwide. Delivery typically takes 3–7 business days depending on your location.

All Mam Nature products come with the following manufacturer warranty: metal parts (connectors, housings, Water LIME, Dynamizer) carry a 10-year warranty on the 316L stainless steel. Filters and non-metal parts have a 2-year guarantee.
