At the heart of every Doulton ceramic filter is the "Sterasyl" ceramic microfilter with embedded silver. The Doulton W9121709 features silver locked within the ceramic structure which inhibits the growth of bacteria and gives the ceramics self-sterilizing properties. Doulton ceramics do not remove the beneficial minerals from the water, ensuring the filtered water is enjoyable to drink and yet safe from harmful impurities. The Doulton Super Sterasyl Ceramic Filter Candle is a self-sterilizing filter with submicron filtration at an economical cost! The Doulton Super Steralsyl W9121709 is a three stage cartridge combining the highly efficient properties of ceramic with the enhanced water treatment properties of activated carbon. The W9121709 has three filtration stages within a single candle and is fitted with a threaded plastic cap on one end. The first stage reduces fine particulate matter, bacteria, cysts and turbidity. The second stage inhibits the growth of bacteria and gives enhanced bacteriostatic and self sterilizing properties. The third stage removes chlorine and organic compounds.
