What's inside
The Swiss Water Cartridge at the heart of every Mam Nature system.
One filter. One installation. One 10-minute swap a year.
At the heart of every Mam Nature system is one cartridge, built around our patented filter media — natural protein fibres bonded to activated carbon. Independently tested at ETH Zürich (Bolisetty et al., 2025).
Our patented filter media is a selective-adsorption media. It binds contaminants on the fibre surface while letting essential minerals pass through. Removal rates vary with source-water chemistry and contact time — see complete ETH Laboratory Report.
Rated flow
Up to 2,000 litres / hour
How long it lasts

How easy it is to swap

Water restructuring
The Swiss Water Dynamizer — moving water like in nature (Vortex)
Purely physical. No electricity, no chemicals, no maintenance.
Water is moved as worldwide standard in straight water tubes rather than a spiral path. The Dynamizer introduces a controlled rotational flow; this is a mechanical description, not a health claim.
The natural movement of water is spiral turbulence, also known as Vortex — the chamber uses this geometry to create rotational and turbulent flow.
The Swiss Water Dynamizer swirls and structures the water in a unique way (18 principles of function).
The result
A passive whole-house spiral-flow stage. Taste is subjective; no digestion, skin, cellular-hydration or energy outcome is claimed.

Installed: 3/1/2023 · Aadorf, Switzerland
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 are very happy!!!! The water tastes much better. Thank you very much.
Cost & savings
