IQ Swiss is a Swiss-technology brand specializing in physical limescale protection for buildings. Its systems are designed to reduce scale deposits in pipes, household appliances and on surfaces without using salt or chemical additives. Installed directly on a building’s main water pipe, each unit sends electronic impulses through the pipe to alter the crystal structure of the water’s scale components. The company says this process leaves the water’s mineral content unchanged while helping limit deposits.

IQ Swiss offers three models for different needs: the IQ Swiss 10 for one- or two-family homes, the IQ Swiss 20 for multi-family buildings and commercial premises, and the IQ Swiss 30 for high-rise buildings and industrial applications. The systems are promoted as maintenance-free and energy-efficient, with low power consumption and a 10-year warranty. They are compatible with metal or plastic pipes installed horizontally or vertically. Customers can compare models, request information and try a system free for two weeks. IQ Swiss also provides product guidance and customer support from its base in Greußenheim, Germany.
