AQUAPHOR softeners are an advanced alternative to the classic whole-home water softeners. The solution is exceptionally efficient, with low salt consumption and small amount of water needed for regeneration.

AQUAPHOR S800 contains 23 L of chlorine resistant ion exchange resin. It is a popular solution for hard water treatment — both in cottages and in city apartments. The system takes up no more space than a washing machine, so there's no need for a separate utility space.

Salt savings up to 60%
Thanks to the unique tank design and extra-fine ion-exchange resin, salt efficiency is maximized.

2-in-1: water softening & iron removal
Removal of high concentration of Fe (up to 15 mg/L concentration in water) and hardness salts.

Exceptionally small water usage for regeneration
The innovative, patented Dual Core Valves of the AQUAPHOR softener assure long-term trouble-free performance whilst wasting minimal amount of water.

Low maintenance
In addition to low salt consumption of the system, ion-exchange resin lasts 10 times longer that in typical water softeners.

Operates efficiently even at very low tap pressure

Fully recyclable body and tank

NSF certified

Aquaphor S800 suits for


• Simultaneous removal of iron, manganese and hardness
