FilterPure promotes Ceramic Water Filter (CWF) technology two reasons. CWFs are highly effective, inexpensive, and simple to use. Made from a mixture of clay, combustible material like sawdust, and fired in nano silver. The filter membrane sits inside a closed receptacle. When water is poured through the membrane, bacteria and pathogens are removed and killed at a rate, of 99.9%. One filter can support a family of six for at least five years and the cost per unit is roughly US$40 or less than 2 cents per day. Secondly, CWFs are appropriate technology,manufactured and distributed locally, a strong candidate for long-term sustainability. Production draws on local, knowledge and raw materials. In this way, CWFs tend to engage a community on its own terms of expertise. When the business is owned and operated locally, as FilterPurestrives for, a social and economic infrastructure is created for CWFs that has the potential to last after external reliefwork and aid ends.
