Household Water Treatment: Ceramic Filtration, 2011. CDC.

Locally manufactured ceramic filters have traditionally been used throughout the world to treat household water.  Currently, the most widely implemented ceramic filter  is the Potters for Peace design. The filter is flowerpot  shaped, holds about 8-10 liters of water, and sits inside a plastic or ceramic receptacle.  To use the ceramic filters, families fill the top receptacle or the ceramic filter itself with water, which flows through the ceramic filter or filters into a storage receptacle.  The treated water is then accessed via a spigot embedded within the water storage receptacle.  The filters are produced locally at ceramics facilities, and then impregnated with colloidal silver to ensure complete removal of bacteria in treated water and to prevent growth of bacteria within the filter itself.  Numerous other locally-made and commercial ceramic filters are widely available in developed and developing countries.
