Sterasyl Doulton Ceramic Water Filter cartridges are highly efficient ceramic micro water filters which provide genuine sub micron filtration of drinking water. Sterasyl is manufactured with the highest consistent and controlled pore structure necessary to remove a wide range of water borne contaminants over the life of the cartridge. Particulate matter, bacteria, cysts and turbidity are removed or reduced to exacting levels of efficiency. Doulton water filters exceed certification standards. The incorporation of silver locked within the ceramic structure inhibits the growth of bacteria and gives each cartridge enhanced bacteriostatic and self sterilizing properties
