Pure Home Water is an organization in Ghana, founded by environmental engineer Susan Murcott, that has developed ceramic water filters as an innovative and low-tech solution to water purification. This device will help to provide cleaner water for people living in northern Ghana, where 50 percent of the population (about 1 million) currently obtain water from an "unimproved source."
The special filters cost about $5 each and work by removing sediment from the water as well as by killing microbes, which is done by coating the filter with silver nanoparticles. To produce and distribute the ceramic water filters, Pure Home Water has amassed a group of local residents and trained them in how to use and integrate the filters into existing homes. According to Fast Co.Exist, there are already 100,000 people involved in the project, and the social enterprise has received an order for 1,250 ceramic water filters in Ghana.
