AquaCera® ceramic elements all start with the CerasylTM, a 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 CerasylTM range is then expanded, to add a granular activated coconut shell carbon core for chemical reduction purposes. AquaCera® ceramics do not remove the beneficial minerals from the water, ensuring the filtered water is enjoyable to drink and yet safe from harmful impurities. comes with washer and wing nut >95% Chlorine reduction and Organics reduction 0.9 Micron absolute 100% removal of cysts >99.99% pathogenic bacteria Cleanable for prolonged life Silver-impregnated to prevent bacteria growth
