is the major cause of death among the world’s children, claiming approximately
5000 victims every day. (WHO 2005) After Hurricane Mitch in October of 1998, the
rural water supply of Nicaragua was largely contaminated. This prompted Potters
for Peace to begin a Ceramic Water Filter production workshop near Managua using
a design developed by a Guatemalan industrial engineer, Dr. Fernando Mazariegos.
The filter element is an approximately 11” wide by 10” deep open-top clay
cylinder which after firing is coated with colloidal silver, a well known
microbicide which remains in the filter for years. The rate of filtration is
determined by the mixture of combustible material, sawdust or rice husks, which
is added to the clay before firing. The fired, treated filter is then placed in
a plastic or ceramic receptacle with a lid and faucet.
In the first six months over 5000 filters were distributed through
non-governmental organizations. The workshop, called Filtron, is now
incorporated as a privately owned business. Potters for Peace has since provided
consultation and training in setting up
production
facilities around the world. Over a million filters have been
distributed worldwide by organizations such as International Federation of the
Red Cross and Red Crescent, Doctors Without Borders, UNICEF, Plan International,
Project Concern International, Oxfam and USAID. Potters for Peace has relied on
partner health organizations to provide appropriate training and education about
filter use. We have financed and or assisted in
laboratory testing and field
studies of the filter with institutions such as MIT, Tulane University
and the University of Colorado.

is simple in design, easy for families to use, and performs exceptionally well
in laboratory tests” (Investigations of the Potters for Peace Colloidal Silver
Impregnated Ceramic Filter, Report 1, Alethia Environmental). The filters remove
bacteria including E.coli and Vibrio cholera as well as Giardia and
Cryptosporidium. Research underway at the University of North Carolina indicates
that with small additions of iron oxide the filter can effectively remove
viruses as well. With proper cleaning, maintenance and monitoring this filter
technology can provide potable water for rural families that draw their water
from surface-influenced, contaminated sources such as springs, rivers, wells, or
standing surface water.

HEART for the
Nations distributes the water filters produced by Potters for Peace in
Guatemala, Nicaragua., Haiti, and Myanmar. These filters are purchased
through donations to HEART. HEART is also developing an education program
to accompany the ceramic water filters
In Haiti HEART for
the Nations distributes the water filters produced by Filter Pure located in the
Dominican Republic.
