Developed by DOST?s Industrial Technology Development Institute, the filter, which is lodged in a plastic container, is made of red clay and coated with nano anti-microbial agent to eliminate water-borne microorganisms. It purifies tap water, deep well water and raw water from ponds and springs. It is a more affordable alternative to regular water filters and does not need electricity.
