Specifications:

• British Berkefeld Sterasyl: ceramic outer shell core 7 inch (L) Gravity Filter Cartridge.
• 0.9 Micron absolute; >98% Efficiency at 0.2 micron; >90% Efficiency at 0.05 micron; 100% removal of cryptosporidium; 100% removal of cysts.
• Cleanable for prolonged life.
• Silver-impregnated to prevent mitosis.
• British Berkefeld Slimline elements are only available in candle format (for use in the Doulton/British Berkefeld rangeof gravity housings) all measuring 2 inches in diameter.
• All ceramic elements are based upon the Sterasyl outer shell with various types of core materials for different applications.
• Water passes through the filter candles from outside to in leaving contaminants on the surface.
• Clean water passes out through the candle mount.
• Filters out: Pathogenic Bacteria (cholera typhoid salmonella E-coli etc.) Giardia Cryptosporidium and other parasites.
• All types of particle contamination.
• Made from food grade polypropylene for strength and resilience.
• 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.
• Doulton ceramic filters are manufactured to a diameter of 2 inchs/50mm with a 1/4 inch BSP threaded mount.
• 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.
