Mediagon® The ecological limescale protection system without salt & chemicals

The sustainable alternative to a water softener.

Mediagon's eco-friendly technology prevents the formation of hard limescale deposits. Instead, a softer residue forms that can be easily removed with a damp cloth. This means less cleaning effort, a longer lifespan for your appliances, and noticeably improved water quality.

Unlike water softeners, Mediagon retains its natural mineral content while protecting your pipes and fixtures from limescale buildup. It's the environmentally friendly solution for hard water – maintenance-free and additive-free.

Since 1986 we have stood for 100% Swiss Made quality and supply not only private households, but also industry, agriculture, hospitals, hotels and restaurants.

Protect your home sustainably from limescale and rust – for noticeably better water quality!

TÜV-certified quality

Mediagon has been tested and certified by TÜV Germany. The test confirms both the technology and the effectiveness of the limescale protection. Independent proof of the highest quality and reliable protection against limescale deposits.

Technology

The image shows the pipe before (left) and after (right) application of Mediagon. The difference is clearly visible.

Innovative technology

Mediagon acts as a catalyst, supporting the natural processes of biomineralization in calcareous water, so that tiny lime crystals can form which no longer harden and are instead washed away with the water.

The valuable minerals such as calcium and magnesium are preserved in this physical process, and the water remains vital, stable, and healthy.

Mediagon also breaks down hard limescale deposits and promotes the formation of a thin protective layer inside pipes and boilers, extending the lifespan of installations and household appliances. No chemicals, electricity, or magnets are required.


A fine protective layer prevents rust.

Water pipes are not perfectly smooth inside – small irregularities in the material are completely normal. These are precisely where limescale and rust tend to accumulate.

Mediagon technology converts limescale in water into a fine limescale dust. This dust is then selectively deposited at irregular points in the water pipes. Instead of hard limescale deposits, a thin, even, and non-adherent protective layer forms – similar to a fine coating. This coating acts as a natural corrosion inhibitor by lightly coating the pipe material and thus effectively preventing further rust formation.
