- Removes existing scale: Soft water begins to descale your system after installation.
- Prevents new scale: Reduces new limescale formation on taps, shower screens and household surfaces.
- Protects appliances: Helps washing machines, dishwashers and showers work more efficiently.
- Kinder to skin: Soft water feels silkier and can reduce the amount of soap and shampoo required.
- Saves you money: Can reduce consumption of cleaning and washing products.
- Bath-time bliss: Less scum and easier cleaning.
