Key Advantages

Why Choose the Aquaphor S800?

Up to 30%

Lower Salt Use

Fine-mesh resin and efficient regeneration reduce salt demand compared with conventional designs.

Up to 5×

Less Regeneration Water

Aquaphor's Dual Core valve design is engineered to minimise the water discharged during regeneration.

23 L

Fine-Mesh Resin

A high-capacity bed of tightly packed, chlorine-resistant ion-exchange resin provides a large treatment surface.

22.7 L/min

Service Flow

Specified service flow at approximately a 1 bar pressure drop for everyday whole-home use.

Whole-Home Protection

Reduce Limescale Throughout the Property

The S800 removes the calcium and magnesium hardness minerals responsible for limescale. Installed on the incoming mains supply, it provides softened water throughout the home.

This helps reduce scale around taps and showers while protecting boilers, cylinders and water-using appliances from ongoing mineral build-up.

  • Helps protect heating and hot-water equipment
  • Reduces scale in kettles and household appliances
  • Less visible limescale around bathrooms and kitchens
  • Metered regeneration based on actual water use

More Than Standard Softening

Hardness and Dissolved Iron Treatment in One System

The S800 combines conventional hardness reduction with the ability to reduce elevated dissolved ferrous iron. Aquaphor markets the system for iron concentrations up to 15 ppm, while its published technical specification lists a 12 ppm ferrous-iron reduction rating.

Hardness Reduction

Reduces dissolved calcium and magnesium responsible for hard-water scale.

Iron Reduction

Designed for water with elevated dissolved iron, subject to incoming water chemistry and installation conditions.

NSF/ANSI 44

Aquaphor states that the system conforms to NSF/ANSI 44 for specified performance claims.

Efficient Regeneration

Designed to Use Less Salt and Less Water

The S800's compact resin bed and patented Dual Core valve architecture are designed to improve contact between the water and ion-exchange media while reducing the resources required during regeneration.

Installation Planning

Check the Space and Plumbing Before You Order

The S800 has a larger cabinet than the S550, but remains compact for a 23-litre resin system. Allow clearance for the plumbing connections, drain, power supply and routine salt replenishment.
