ETH Zürich-Certified Contaminant Removal
The Swiss Water Cartridge has been independently tested at ETH Zürich — 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 material chemistry alone.
Same ETH-certified cartridge
The Essential uses the exact same Swiss Water Cartridge as our larger systems. The certification 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 clean and clear, The Essential gives you the same ETH-certified filtration as the larger systems with one less component.
What's the difference between The Essential and Essential Plus?
Essential Plus adds an auto-backwash particle pre-filter, which protects the 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 material 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.
