How does Maitron LimeSafe work?
Maitron LimeSafe changes dissolved limescale in the water into a form that no longer adheres stubbornly to surfaces. This helps protect plumbing, water heaters, fixtures and appliances from hard limescale buildup – without salt, chemicals or electricity.
The Basic Principle
Inside the Maitron LimeSafe unit is a specially developed granulate with an active surface. When water flows through the unit, tiny limescale seed crystals form on this surface. These crystals are carried along with the water and continue to bind dissolved limescale.
This creates fine limescale crystals that no longer attach firmly to surfaces. As a result, hard limescale deposits are significantly reduced.

The minerals remain in the water – but no longer stick
Maitron LimeSafe does not remove limescale from the water. The minerals remain naturally present, but they lose their ability to form hard, stubborn deposits.
The water keeps its natural composition and is not altered by salt or chemicals. The unit works without any special maintenance.
- no salt
- no chemicals
- no electricity
- no consumables
- maintenance-free
Why limescale stresses technical systems
Minerals dissolved in water can build up in pipes, water heaters, shower screens, ceramic surfaces and fixtures as hard deposits.
Limescale on heating elements acts like an insulating layer. This means more energy is required to heat the water, and the service life of technical equipment can be reduced.

The difference compared to traditional water softeners
Traditional water softeners usually work with salt, regeneration cycles and regular maintenance. Maitron LimeSafe works without salt, without chemicals and without changing the natural mineral composition of the water.

Existing deposits are gradually reduced
In existing installations, old limescale and corrosion layers can gradually be loosened and reduced. This process may take several months, depending on the condition of the plumbing system and the amount of water used.
During this initial phase, slight cloudiness or particles in faucet aerators and shower screens may occur. This can be a sign that existing deposits are being loosened.
Good to know:
After installation, older plumbing systems may temporarily release particles into faucet aerators or shower heads. These can usually be rinsed out easily during the first weeks.
