Ceramic Water Filters

Silver enhanced ceramic water filters were first developed in Guatemala in 1981 by Dr. Fernando Mazariegos. The filters caught on in 1994 when an organization promoting health education found that chlorine tablets were being widely rejected by rural Guatemalan communities. In 1998, Hurricane Mitch tore through Central America, leaving millions without food, water or shelter. In response, Potters for Peace (PFP) began a major effort to mass-produce affordable, silver-coated ceramic water filters. Since then PFP has established ceramic water filter factories in thirty two countries around the globe.

In Kenya, the ceramic filter factory (Chujio Ceramics) was established in 2007 by Ron Rivera of Potters for Peace with the assistance of Kaira Wagoner and Reynaldo Diaz of Claysure USA.

The ceramic water filter is a point-of-use water treatment technology that is effective in reducing bacterial contamination in water and the risk of water borne illness.  The ceramic water filter works in two basic mechanisms, gravity filtration and disinfection with colloidal silver.   Filtration removes contaminants from water through sorption and screening.  
Sorption is the settling of particles onto the filter surface while screening is the prevention of particle movement through the filter pores due to size restrictions. With time and continual use, the pores of the filter diminish in size due to clogging and therefore become more efficient in retaining particulates from the water.   
As water passes through the ceramic water filter it is disinfected with colloidal silver.  Silver acts as an antimicrobial agent which kills the microorganisms in water.

Drinking untreated water can result in exposure to harmful microorganisms and an increase in waterborne diseases. Proper use and maintenance of the filter is therefore advised. Please read and follow the instructions manual carefully before using your Chujio water filter.

Chujio water filters do not remove chemical contaminants and viruses therefore it cannot be used to treat water from agricultural areas, mining wells and water that contains chemical contaminants or particles smaller than 0.2 microns.
