How does the ceramic pot become so porous?
Ceramics are inherently porous. However, our specialized process of firing the clay and rice husk mixture causes the rice husks to completely burn away in the intense heat of the kiln. When the rice husks burn out of the mixture, micro pores remain in the newly created ceramic filter which allow for a perfect seepage of water minus the harmful microbes that once infected it. Question: What maintenance does the ceramic filter require? Answer: If the water is turbid or cloudy or has a lot of solids in it then it needs to be periodically cleaned with a soft bristle brush.

Question: How do you know that it works in the village? Do families really use this? Answer: Part of the commitment RDI has for maintaining a its community focus for sustainable change is to insure the viability of the filters. The fil
