• At the heart of every Doulton and British Berkefeld ceramic filter is the Sterasyl silver impregnated ceramic microfilter.
• The incorporation of silver locked within the ceramic structure inhibits the growth of bacteria giving the ceramics self-sterilizing properties and removes the need for boiling of the filter to remove or kill the impurities within the ceramic pores.
• The Doulton range of ceramic filter elements starts with the Sterasyl and with added core medias can become a three stage filter in one eliminating the need for expensive 4 and 5 stage systems.
• 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.
• They have the highly consistent and controlled pore structure necessary to remove a wide range of water borne contaminants over the life of the filter.
• All genuine Doulton ceramic filters are manufactured in accordance with ISO 9001:2000 quality assurance procedures which ensures highly consistant product quality with full batch traceability in operation.
