The best and most enduring solution against the formation of limescale

Prevent limescale formation in domestic water systems and save maintenance time and costs with Alpwater’s revolutionary technology!

Alpwater is a magnetic device that prevents the formation of limescale while preserving the chemical composition of the water and guaranteeing hard water treatment in full respect for the environment.

The magnetic anti-limescale system for the entire home

The result of years of research, Alpwater is the unique and lasting solution to prevent the formation of limescale in domestic water systems saving on the times and costs of cleaning and maintenance.

Dishwashers, washing machines, coffee makers, boilers, and also taps, wall tiles and shower cubicles are the first to suffer the negative effects of the deposition of limescale contained in domestic water supplies.

Not only is limescale formation among the main causes of problems in home appliances and heating systems, through time this phenomenon reduces their efficiency and increases electricity consumption.

How does the ALPWATER magnetic anti-limescale system work?

Alpwater is your precious assistant to solve the problem of hard water caused by the presence of large quantities of Calcium and Magnesium.

Alpwater uses powerful magnets, studied and positioned with optimal shapes and angles, to prevent these two minerals in the water supply from aggregating to form calcium carbonate and hence preventing the formation of limescale deposits.

Calcium and magnesium are both elements with a positive effect on health. Rather than removing these two important minerals, Alpwater prevents the crystallisation process that gives rise to the formation of limescale.
