$21 Tata Swach: The World’s Cheapest Water Purifier?

Tata Swach

India’s Tata Group is famous for launching the the world’s cheapest car, the Nano compact. Now the company is taking on the challenge of providing clean drinking water to the 894 million people worldwide who lack access to it. The Tata Swach (Hindi for “clean”) doesn’t require electricity or running water. And at less than $21 a pop, the device is purportedly the cheapest water filter in existence.


Tata plans on launching the filter first at a plant in West Bengal. Initially, the company will produce 1 million units a year, with 3 million units each year expected to be produced within 5 years. India will have first dibs on the product–a big market considering 85% of the country drinks unfiltered water–but ultimately Tata hopes to export the filter to Africa.
