In a revolutionary move, researchers have developed a kind of paper that can filter dirty water of up to 99% of pollutants. The Drinkable Book is an instructional and functional object which can provide potable water for millions of people.

Using silver and copper nitrates as a filtration system, the pages of the Drinkable Book are not only intended to provide safe drinking water tips in writing, but can filter clean drinking water for up to four years.

The filtration system was tested in sites in South Africa, Ghana, Kenya, Haiti, and Bangladesh. Teri Dankovich, one of the project leaders from Carnegie Mellon University in Pittsburgh, says, "Even with highly contaminated water sources like (those), we can achieve 99.9% purity with our silver-and copper-nanoparticle paper, bringing bacteria levels comparable to those of US drinking water.”

One page of the book alone can filter up to 26 gallons of water. The books are cheap to produce, and designers are looking to step up production to target communities in need.

Facts about drinking water:

Currently, as many 385 million people in Sub-Saharan Africa alone do not have access to clean drinking water.

Around 500,000 people die every year from diarrhea caused by inadequate drinking water.

Globally, more than two and a half times the population of the United States lives without access to clean, safe drinking water.
