WHOLE-HOUSE WATER FILTRATION
Essential Plus
Family-sized protection. Same ETH-laboratory confirmed cartridge, longer service life.
Best for: Families · 2–4 people · Sediment-prone water
The Mam Nature Essential Plus is among our most popular whole-house systems. It pairs the ETH Zürich-laboratory confirmed Swiss Water Cartridge with a high quality particle pre-filter, so every tap delivers clean, mineral-preserving water — and the cartridge lasts longer thanks to upstream sediment protection.

What's inside Essential Plus
Two components, installed at your home's point of entry, working in sequence to clean and protect your water before it reaches any tap.
Auto-Backwash Particle Pre-Filter
High quality Particle Filter at 90 µm. Removes sand, rust and sediment before they can load the cartridge or damage downstream appliances. The optional automatic backwash runs the backwash cycle according to your individual needs – typically 15 seconds once or twice a month – and shows the next cycle on its display.

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 families choose Essential Plus
Longer cartridge life
The pre-filter catches sediment before it loads up the cartridge — practical service intervals extend, especially in homes with rust or sand in the supply.
Salt-free, chemical-free
No salt, no resin, no chemicals. The cartridge is fully passive; the particle filter's only "active" part is its low-voltage backwash controller, which runs once or twice a year on its own.
Preserves natural minerals
Selective filtration removes contaminants but leaves calcium, magnesium and trace minerals intact — so your water stays mineral-rich.
10-minute annual maintenance
Replace the cartridge once per year — no tools, no plumber. The particle filter handles its own backwash automatically, and the display tells you when the next cycle is due.
Frequently asked questions
What's the difference between Essential and Essential Plus?
Essential Plus adds a high quality Particle Filter. It removes sediment, sand and rust at 90 µm before they reach the Swiss Water Cartridge. In homes with sediment-prone water, this can significantly extend cartridge life — the cartridge stays cleaner for longer.
How often do I need to replace the cartridge?
Once a year, or every ~150 m³, whichever comes first. The Particle Pre-Filter doesn't need any kind of Cartridge Change – however, the Particle Pre-Filter protects the Fine Filter Cartridge from Particle Charge and needs to be backwashed (optional automatic backwash) usually once a month for 15 seconds.
Does Essential Plus protect against limescale?
No. Essential Plus is designed for contaminant removal. If you also need limescale protection, the Complete Set adds Water LIME — a magnetic anti-limescale converter that requires no salt or electricity.
Is electricity required?
Only for the particle filter's optional automatic backwash unit, which runs the self-cleaning cycle once or twice a year and shows the next cycle on a small display. The Swiss Water Cartridge itself is fully passive — no power, no salt, no chemicals — and it does the actual filtration.
How long does installation take?
Installing the Essential Plus Set can be done with ideal conditions in 2–3 hours. Compact dimensions and 360° connectors make it straightforward to fit in most utility spaces. Due to the usual conditions of your Water damage insurance, the installation should be executed by a professional plumber.
