The Replacement filters maintain the high levels of filtration that the Watts 4 stage system provides, maintaining your, virtually, pure water.
The water passes through a pre-filter which takes out particles larger than 5 micron. A carbon filter then removes chlorine, cysts and trace organics before being forced through a 0.001 micron membrane thus creating the finest filtration, flushing away any impurities and allowing only the purest of water through to the pressurised holding tank. When the tap is opened filtered water is passed through an in line activated carbon filter which effectively polishes the water prior to consumption. Creating the purest water you are ever likely to taste.
The replacement filters offer almost pure water filtering out up to 98% of the impurities and minerals.
The filters are sold as a set. The set contains a 5 Micron Pre-filter, Carbon Block Filter and In-line Activated Carbon Filter
