With the AquaShield, water entering the filter is forced through millions of tortuous microporous pathways. Each drop of microbe carrying water touches the Microban filter walls destroying and inhibiting the growth of water borne microorganisms such as Legionella, Fecal Coliform and Cholera. The filter is effectively protected against stain and odor causing mold, fungus and bacteria. Microban is non-leachable, non-heavy metal, tastless, odorless and colourless – it is used extensively in the medical and food industry
