VITOPURE S3: soft water throughout your home
Viessmann S3 filters soften your domestic water by extracting minerals like calcium or magnesium to prevent limescale and to increase the lifetime of your water-using appliance. At the same time, soft water is ideal for hair and skin care. S3 filters are high-capacity devices which are available at two or three cubic metre flow rate per hour.
Benefits at a glance:
- Reduces water hardness by filtering minerals like calcium and magnesium
- Prevents scaling and increases the lifetime of home appliances
- Protects skin and hair
- High capacity filters for constant soft water supply
- Auto-program for easy operation

Resin and salt for filtering and regeneration
Viessmann water softeners work through a process called ion exchange which eliminates minerals like calcium and magnesium from the water. Resin neutralizes the minerals. Given its smooth surface, it makes water purifiers run efficiently for a long time. Adding salt to the purifier enables the regeneration of resin - minerals are flushed away with waste water.
