All our relatives now have purifiers, we bought the doucisseur, and after 2 months the water is really, really softer (it was very hard). it's spectacular!

EXCELLENT

Based on 1143 reviews

Reduces the creation of limescale on water supply components (pipes, valves, taps, shower heads, water heating coils on household appliances) - efficiency of 78%.

100% compatible with LaVie treatmentIt does not affect the quantity of trace elements. The little limescale that forms after installation is in the form of non-sticky dust, and can be removed with a damp cloth.

No maintenanceNo adjustment required, works with both cold and hot water.

Six-month money-back guarantee.

Put an end to limescale without maintenance or pollution
Discover Odouce

The system Odouce uses a anti-limescaleThe system consists of a galvanic membrane that automatically activates a turbine of electrodes when water passes through it.

This revolutionary technology will make it possible to forget the problems caused by limescale.
The turbulence created in the system removes a tiny quantity of zinc by ionisation (electrolysis), which modifies the calcium carbonate by forcing it to take on a non-sticky powdery form, aragonite, instead of the sticky crystalline form known as calcite. The reaction is written as  Zn2+ + 2HCO3- ZnCO3 + H2O + CO2

The result? An effective treatment against limescale and scale, which is ultra-simple to install and requires no specific maintenance. The treatment has a preventive and curative effect. On a system clogged with limescale, the aragonite will gently abrade the calcite until the pipes are completely clean. This can take up to 3-4 months, depending on the amount deposited, and you'll see white dust accumulate at the taps, which you can wipe away with a damp cloth. That's why you get a six-month trial, so you have plenty of time to see how effective the product is.

Enhance your water with Odouce! 

Protect your water heater against limescale build-up

It requires no power supply, batteries, chemicals or filters.

Without ODouce

With ODouce

These heaters underwent 40 heating cycles over 11 days in a 120l hot water tank before being dismantled.

Odouce uses a patented turbulent galvanic polarisation electrode to disrupt the formation of limescale crystals on water heater elements. In side-by-side comparative tests, the resistance of the Odouce-protected electric water heater created four times less scale (weighed with an electronic balance) than that of the water heater without the protection.

 

Odouce is easy to install and requires no maintenance. It comes with a 5-year guarantee and a projected lifespan of around 10 years. It is installed at the water meter outlet, or at the water inlet to the home. Both connections are 3/4″ female, simply follow the direction of the blue arrow printed on the body of the product to the right of the logo.

Environmental impact Positive, no chemical waste, no electricity consumption Positive, but CO2 needs to be recharged Positive, chemical-free Negative, use of salt, discharge into waste water Positive, low impact Positive, low impact
Durability Long service life Long-lasting, if properly calibrated Long term Average, depending on maintenance Medium to long Medium to long
Disadvantages Slightly higher initial investment than systems such as magnetic or electronic limescale removers High installation cost, requires regular refills of CO2, risk of corrosion if incorrectly calibrated Less effective in very hard water, higher initial cost Environmental impact, consumption of salt and water, costly maintenance Limited effectiveness in areas of very hard water, depending on the strength of the magnets Requires a source of electricity, efficiency dependent on the quality of the system
