The Swiss Water Cartridge — ETH Zurich Certified Contaminant Removal

Our 100% natural Mam Nature Swiss® exclusive filtration technology combines natural protein fibers with activated carbon to achieve perfect filtration — a world first. The Aqualen™ fibers use molecular-level protein adsorption to selectively capture PFAS (forever chemicals), heavy metals (lead, cadmium, arsenic), drug residues, chlorine, pesticides, BPA, and even radioactive substances at retention rates of up to 99.98%.

Unlike reverse osmosis, the mineral ions your body needs — calcium, magnesium, and potassium — pass through unchanged. The result is water that is not only exceptionally pure but also naturally mineralized and pleasant to drink.

As a whole house solution (POE), the Swiss Water Cartridge eliminates contaminants while preserving minerals and trace elements naturally present in water — delivering filtered water to every tap in your home without any noticeable pressure loss.

Certifications held: ETH Zurich Filtration Performance Certificate · ISO 13485 Quality Management · Swiss Safety Center Pressure Test Certificate (16 bar) · All components manufactured in 316L medical-grade stainless steel with no lead-containing brass parts.

What contaminants does the Swiss Water Cartridge remove?

Certified by ETH Zurich, the cartridge removes PFAS (forever chemicals), heavy metals (lead, cadmium, arsenic), BPA, pesticides, chlorine, pharmaceutical residues, aluminum, and even radioactive substances — all at retention rates of up to 99.98%. It also reduces fluoride by 57.9%.

Does the cartridge remove beneficial minerals?

No — this is the core advantage of the Aqualen™ protein-fiber technology. Unlike reverse osmosis, which strips everything including minerals, the selective adsorption targets harmful contaminants while allowing beneficial mineral ions (calcium, magnesium, potassium) to pass through unchanged. Your water remains naturally mineralised.

How often does the cartridge need to be replaced?

The Swiss Water Cartridge is replaced once per year (or after 150 m³ of water, whichever comes first). Replacement takes approximately 10 minutes and requires no tools — simply unscrew the housing, swap the cartridge, and close.

What is the flow rate?

The cartridge delivers up to 2,000+ liters per hour — among the highest in the industry. This means zero noticeable pressure loss and instant access to filtered water from every tap, even when multiple outlets are running simultaneously.

How is this different from a Brita or jug filter?

Jug filters are countertop devices that filter only cold drinking water at a low flow rate, typically replacing carbon every 4 weeks. The Swiss Water Cartridge treats all water entering your home, achieves up to 99.98% removal of PFAS and heavy metals (vs. partial removal by carbon jugs), lasts 150 m³ per cartridge, and is certified by ETH Zurich — a standard no consumer jug filter meets.

Is the cartridge compatible with all Mam Nature systems?

Yes. The Swiss Water Cartridge fits into the Water Fine Filter housing, which is included in all system sets (Complete Set, Complete Set Plus, Essential, Essential Plus, Eco Set). It can also be purchased separately as a replacement.
