How the Twin Cylinder Softener Works
The two softening filters remove the hardness from the water, and once half a tonne (500 litres) of soft water has been used at home, one of the two filters completes a 9 minute regen water-powered clean.
Just 300 grams of block salt, and a few litres of flushing water are required to make the filter ready to roll.
Inside each of the two filters is high quality Ion Exchange Resin. It collects the hardness minerals as the water passes through it into your home and exchanges with sodium ions.
The easy to load 4kg salt blocks dissolve slowly down at a rate of approx. 1 block per person in 5 weeks. Note that the addition of children in a home tends to add less salt usage due to the shared use of the appliances etc.
