ETH Zürich-Laboratory Confirmed Contaminant Removal
The Swiss Water Cartridge has been independently tested at ETH Zürich University — consistently ranked among the world's top 10 universities. Verified retention rates across major contaminant categories:
Selective filtration: contaminants out, calcium and magnesium left in.
Why choose The Essential
100% passive — no electricity
No power, no salt, no chemicals, no controllers. The cartridge does all the filtration on water pressure and filter media chemistry alone.
Same ETH-laboratory confirmed cartridge
The Essential uses the exact same Swiss Water Cartridge as our larger systems. The laboratory confirmation doesn't change with the system size — only the surrounding components do.
Preserves natural minerals
Selective filtration removes contaminants but leaves calcium, magnesium and trace minerals intact — your water stays mineral-rich.
Compact, modular footprint
One housing, one connection. Fits into nearly any utility space, and you can add the particle pre-filter, Water LIME and Dynamizer later as standalone upgrades.
Frequently asked questions
Who is The Essential right for?
Sediment-free supplies, smaller households (1–2 people), apartments, or anywhere rust and sand aren't an issue. If your municipal water is already filtered by an existing Particle Filter, the Essential gives you the same ETH-laboratory confirmed filtration as the larger systems with one less component.
What's the difference between The Essential and Essential Plus?
Essential Plus adds an automatic (optional) backwash particle pre-filter, which protects the Swiss Water Cartridge from sediment and rust and extends its practical life. If your supply has visible particles, the pre-filter is worth it. If not, The Essential is enough.
How often do I replace the cartridge?
Once a year, or every ~150 m³ — whichever comes first. Replacement takes 10 minutes with no tools.
Is electricity required?
No. The Essential is fully passive — no power, no salt, no chemicals. The Swiss Water Cartridge does all the filtration on water pressure and filter media chemistry alone.
Can I upgrade later?
Yes. The Mam Nature system is modular — you can add an auto-backwash particle pre-filter (becomes Essential Plus), Water LIME for limescale, and the Swiss Water Dynamizer for taste, one at a time.
