Chowdhury, 26, co-founded Drinkwell to provide affordable filters to clean up contaminated drinking water. The US$8,000 filter is now used at over 200 water sources for 250,000 people in Bangladesh, Cambodia, India, Laos and Nepal. Drinkwell Systems’ filters are 40 per cent cheaper and produce 60 times more water than current best options. Local entrepreneurs sell the water and keep most of the profits.
