Studies on the ceramic filters have been conducted at over 40 universities including MIT, John’s Hopkins, Yale, Harvard, and Rice, in the USA, Cambridge in the United Kingdom, and UNICEF and the American Red Cross to mention just a few. These studies have proven the filter’s effectiveness of 99% removal of all fecal coli form, e coli and streptococcus bacteria. Many university studies have led to the establishment of filter factories in the third World. Here are some interesting documents and research studies written over the past decade.
