What is the benefit of using an additive salt in a water softener?

AQUA PROTECT® tablets contain an exclusive active agent: s-Protect®, which removes metallic deposits from the water softener resin that could otherwise clog it.

This helps the resin last longer. AQUA PROTECT® salt is therefore more effective against certain elements:
• 20% more effective against limescale 
• 3 times more effective against lead 
• 2 times more effective against iron 
• 2 times more effective against aluminium
