A water softener, what for?

Water softeners: salt machines

From very useful to bought by mistake, let's take a closer look at the results of these salt machines ...

Some of you have already taken the plunge, but are still confused about what has changed.

Let's take a chemistry tour around the calcium ion, which is the dissolved form of limestone, or tartar, the one that exists in the water inlet of the meter.

This trace element is one of the most important for our body, it allows among other things to transport the electrical signals that our brain sends to our muscles. We try to absorb it in mineral water, cheese, milk etc...

Preserve the trace elements in tap water with LaVie

bouteille purificatrice d'eau LaVie pure

LaVie UV-A water purifiers® work without filters or maintenance and allow you to purify your tap water in 15 minutes.

They use an innovative technology, patented and exclusive to LaVie®: the photolysis of chlorine by UV-A radiation.

This treatment allows the removal of chlorine and its derivatives, chemical compounds such as certain pesticides or traces of medication, and tastes and odours that can be found in tap water.

The result, which is very qualitative, makes it possible to draw a definitive line on the consumption of water in plastic bottles.

The carbon footprint linked to the manufacture of the aluminium tube of the UV water purifier is neutralised in a few days of use compared to the equivalent consumption of water in plastic bottles.

Why not drink calcium ion available in tap water?

False rumors blame him for kidney stones, this is completely false. All excess calcium is eliminated by our body, so we do not need a water softener for our drinking water, on the contrary, it is a necessary element in order to qualify the water as "drinkable".

On the other hand, there is a mineral that our body cannot reject if consumed in excess in our diet, and that is salt.

Well, it's odd to say the least, but a water softener replaces calcium with the same amount of salt, yes the famous NaCl from our salt shaker!

In addition, a water softener requires maintenance, from 135 € / year for a contract that includes maintenance, filters and salt (source https://www.savadou.fr)

This takes place on what are called ion exchange resins.

These resins need maintenance and replacement once or twice a year, and generate pretty pollution in the process, mainly because of the cleaning water that will come out salty, not kind to our water tables. Maintenance also consumes a lot of water. Resins if not maintained can cause bacterial pollution, as can a filter jug ​​filter not replaced in time.

So the seller’s argument remains: it will extend the life of your water heater and appliances. I advise you to ask them for the study that proves it before signing any commitment: Removing calcium makes the water acidic, adding salt makes it ultra corrosive to metals.

Just as it is easy to throw two spoons of citric acid in your washing machine or coffee maker to melt the limestone, so it is impossible to regenerate the corroded metal by this pickling and salty water.

Conclusion, if you can avoid it, do not use a water softener, nature will thank you for it.

If you have one, try to make a bypass upstream to fill your bottle with drinking water, this is our advice.

We will explain to you in a future publication how to avoid transforming the calcium ion into its crystalline form, until then, know that there are systems to neutralize the lime by injection of CO2, without environmental damage, respectful of your health.

We are confident that you now know enough to make a more informed choice, be well aware that the cure may be worse than the ailment.


  • Bonjour Ghyslaine,
    La solution se nomme anneau sialex, elle est disponible chez notre partenaire Ethic Process qui distribue aussi les solutions LaVie, qui fonctionnent en parfaite symbiose avec ce produit.
    Ses coordonnées sont là : https://eau-traitement.com/

  • Bonsoir Ghyslaine,
    Il existe de solutions bien plus écologiques et saines que les adoucisseurs à sel, je les décrirais la semaine prochaine dans cet article. L’une est à base de Co2, l’autre à base d’un anneau à monter sur l’arrivée d’eau, et dans les deux cas, il n’y à aucune nuisance environnementale, et cela reste moins onéreux qu’un adoucisseur à sel.

  • Bonjour, par quoi remplacer un adoucisseur alors? chez moi, l’eau est très dure et abime tous les appareils ménagers. Que proposez vous comme solution? je ne parle pas de l’eau à boire, bien sûre.
    Merci d’avance, cordialement, Ghyslaine

  • Bonjour,
    j’ai un adoucisseur ET un osmoseur. Dans ma région, l’eau est très calcaire ce qui abime à priori les appareils ménagers. Quelle est votre solution? je voudrais bien arrêter mon contrat à sa prochaine échéance et je cherche des substitutions au sel.
    Cordialement, Ghyslaine
