news-dost developed2liter ceramic water filter-09082015

To address the need for potable water in far flung areas in the provinces and as emergency water system during disasters, the Department of Science and Technology developed this ceramic water filter in cooperation with the University of Northern Philippines (UNP) in Vigan City, Ilocos Sur. The ceramic water filter is portable and uses red clay filtering agent with nanotechnology silver coating with anti-microbial feature. This system uses the principle of gravity, and the UNP-produced system can filter tap or deep well water at the rate of two liters per hour. Moreover, it is relatively cheaper than commercially available filtering systems. The filter can last up to one year before replacement.
