Shudh Pani is a water purifier that costs approximately $1.50 and uses cotton, sand and charcoal as purifying agents. These elements together can purify 98 percent of the water, thus avoiding diseases like cholera and diarrhea. The purifier is made to sit on top of the traditional matka (water pot) that villagers already own so the purifier can become a natural addition to their way of life. The only maintenance required is to wash and dry the cotton cloth and the pot.
