Scale Prevention

The scale prevention takes place within the filter cartridge without adding any salt or chemicals into the water. The filter does this by using a process called Template Assisted Crystallization (TAC), which basically conditions the water and converts the hardness minerals in the water (Calcium and Magnesium) into harmless, inactive microscopic crystals. This prevents the Calcium and Magnesium from bonding together to form limescale, and also over time will descale existing pipework and appliances. Because of this process no natural minerals are lost from the water, and no chemicals or salts are added either. Water which has undergone this filtration process has a softening effect which prevents scale from forming in pipework and appliances, around sinks and washbasins, and will help prolong the life and efficiency of your appliances. The scale prevention media is effective even in the hardest water areas has been tested independently against the international protocol for scale prevention with a 99.6% effectiveness rating. You will need to replace this second filter on the system just once every 3 years (depending upon incoming water quality).
