Researchers from the Indian Institute of Technology Madras have developed an inexpensive water filter that could bring potable water to those who need it most (as little as $2.50 per family per year).
There have been other cheap water filters, but this one is able to remove bacteria, viruses, arsenic, lead, pesticides and other contaminants using nano particles that release streams of silver ions that eliminate microbes.
The researchers added other materials to the filter cartridge to remove pesticides, lead, and other heavy metals.
Filtration takes about an hour for ten liters of water.
People and families without access to safe drinking water, first in India and then hopefully around the globe
Identify areas in India with the greatest need and where distribution would be able to reach a wide number of people
Implement educational programs on what the technology is and how it works
Establish distribution centers where people can purchase the filters
