CSC 20″ city water filtration station - Total protection at the entrance to the house

Why install a CSC 20″ station?

  • Protect your installations: limit the impact of limescale on your pipes, taps, water heaters, washing machines and dishwashers.
  • Improved sanitary water: reduction of tastes and odours linked to chlorine and pollutants.
  • Ecological solution: no salt, no electronics, no water waste.
  • Easy to use: no adjustment, no complex maintenance.

Note: for complete potabilization of drinking water (PFAS, nitrates, heavy metals, viruses, bacteria, new contaminants, etc.), we recommend downstream addition of a non-reservoir osmosis unit, with vortex and plant mineralization.

Ecological & economic benefits

  • No salt or chemicals required
  • No electricity consumption
  • No water discharge to treat
  • Protects your installations and extends their lifespan
  • Reduces scaling, breakdowns and costly maintenance work

How do you filter city water at the front door without a salt softener?

The CSC 20″ filtration station treats incoming general water without salt, electricity or electronic programming. It combines three complementary actions: scale inhibition (food-grade silico-polyphosphate), filtration of particles and sediments, and reduction of chlorine, PFAS, pesticides and VOCs thanks to the activated carbon block. Unlike a softener, it does not alter the water's natural mineral content, and generates no saline discharge.

What's the difference between an anti-scale filter and a softener?

An anti-scale filter modifies the crystallization of calcium carbonate to limit scale adhesion.
A salt softener exchanges calcium/magnesium ions for sodium.
The CSC station works without salt, without rejects, without electronics or electrical connections, and without water loss.

Is it possible to filter the whole house with a compact system?

Yes. Installed on the cold water inlet with by-pass, the CSC station protects pipes, water heaters and household appliances while improving domestic water quality.

Does the CSC 20″ reduce PFAS?

Yes, the activated carbon block (Ref. CSC10-3) helps reduce PFAS, VOCs and organic residues in tap water.

How do I choose between CSC 10″ and CSC 20″?

  • Choose the CSC 10″ if you live in an apartment with a water point, or if your consumption is low to moderate (smaller cartridges, shorter average life).
  • Choose the CSC 20″ if you live in a house, with several water points or higher consumption (larger cartridges, higher filtration capacity, less frequent renewal).

→ Fewer changes, fewer constraints for large families or high consumption.

Wound sediment filter: performance

No, it's deliberately selected: consisting of a wire wound around a central core, it's more mechanically resistant and better suited to the high flow rate required.

Easy renewal and maintenance

Recommended option: flexible by-pass with loose nuts. Allows you to isolate the filtration system without cutting off the general water supply.

Cartridge composition

  • 1st cartridge (Ref Filtermax): manual self-cleaning sediment filter, removes suspended solids > 100 microns (pressure gauge included).
  • 2nd cartridge: anti-scale treatment with food-grade polyphosphate (Ref CSC1-20).
  • 3rd cartridge: braided polypropylene sediment filter (Ref CSC2-20), retains rust and matter > 50 microns.
  • 4th cartridge (Ref CSC3-20): coconut activated carbon block + 10-micron mesh, to reduce persistent pollutants/PFAS, tastes and odors, COD, VOCs (iodine 800...).

COD: "Chemical Oxygen Demand", measures the quantity of organic matter in water (variable according to persistent pollutants, particularly pesticides).

VOC: "Volatile Organic Compounds" (petroleum derivatives, halogenated compounds containing chlorine, fluorine, iodine, etc.).

Filter life

  • 12 to 18 months maximum for 20″ cartridges (depending on incoming water quality and volume filtered).
  • The self-cleaning filter must be rinsed every year or as soon as the pressure increases.
  • After washing the filter holders, apply Osmodyn silicone grease to the O-rings.
  • Renewal does not require a specialist.

Secure tank opening

Transparent polycarbonate bowl to fit standard 20" filters.

Secure assembly and opening: unlike the basic/blue head model, the black head's clamping hook is positioned higher up, reducing the risk of the key slipping.

Description

1 self-cleaning filter holder + 3 20" filter holders, 20x27 connection, removal key, 1 pressure control gauge, 4 filters + by-pass option.

Installation (reminder)

  • Connect the station to your main cold water supply, ideally with a pressure reducer upstream.
  • If necessary, reposition the filter holders and cartridges in the IN-OUT direction.
  • Turn on the water and allow the air to bleed through the bleed valve.
  • Check for leaks.
  • The filtered water now circulates throughout your entire sanitary installation.
