Perry Alagappan is already a Water hero

Perry invented a filter through which toxic heavy metals from electronic waste could be removed from water. This first-of-its-kind filter removes over 99% of heavy metal contaminants from drinking and industrial wastewater.

Perry became interested in water purification after visiting his grandparents in India, seeing first-hand how electronic waste severely contaminated the environment. Three years after he returned home, after intensive research and experimentation (Perry is interested in water and nanotechnology), Perry won the Stockholm Junior Water Prize for his invention.

Instead of patenting his discovery, Perry wants to launch his study as an open source technology that others can use and build upon in their research. Now that’s a waterhero.
