Combating limescale

Thanks to its magnetic action, this ring acts against limescale deposits in your toilet, reducing the growth of bacteria !

It extends the life of your equipment and reduces the consumption of detergent products. Its action is continuous for many years.

The anti-limescale ring has become a highly effective classic for combating limescale.

It's a clever product that deserves to be better known, because few people use it any more ! And yet there are so many advantages: easy to use, economical and environmentally friendly, the anti-limescale ring generates real savings on detergent products.

The magnetic effect will enable you to significantly reduce limescale deposits in the toilet bowl and its frequent cleaning with aggressive and expensive products.

As a result, the bowl will give off fewer unpleasant odours and be more hygienic, as scale deposits are a breeding ground for bacteria.

The principle is simple

A ferrite magnet is inserted into the ring, generating a magnetic field. This field momentarily modifies the structure of the limestone crystals dissolved in the water (transformation into discoid crystals). This modification reduces the tendency of limescale to adhere to surfaces, including inside the toilet cistern. The result is a reduction in limescale deposits in the toilet cistern.

The disadvantages of limescale

The presence of limescale in the toilet cistern is mainly due to the quality of the water used to supply your home. When water flows through soil and underground rocks, it can dissolve minerals, including calcium carbonate. This calcium carbonate then finds its way into the tap water, and when it fills the toilet cistern, limescale deposits form over time. This is a common phenomenon in regions where the water is hard, meaning that it contains a high concentration of minerals such as calcium and magnesium.

Limescale deposits mainly in the form of scale, which can lead to a number of problems in the toilet. Limescale deposits can clog valves and internal tank mechanisms, which can reduce flushing efficiency and lead to leaks. What's more, limescale can cause unsightly stains inside the tank and on the toilet bowl.

How do I use this anti-limescale ring ?

Simply place the anti-limescale ring in your toilet cistern. It works without any chemicals, so your toilet always stays spotless (it eliminates bacteria, bad smells, etc.). Wear-free, it requires no maintenance.


Ferrite magnet and ABS plastic.

Precautions for use

The anti-limescale ring is magnetic. Be careful not to place it near other devices such as mobile phones, smartphones or pacemakers. The magnet loses its effectiveness after about 5 years. Don't forget to replace it !
