This anti-scale filter is easy to install on the standard supply piping of the washing machine without needing any intervention on the water system.
The DOSAL washing machine anti-scale filter eliminates all problems related to deposits and limescale, polyphosphates dissolved in water have a conditioning effect on carbonates preventing them from depositing onto pipes and heaters.
