Users can tear out a filter page, slide it into a custom filter box provided and pour contaminated water through. According to Dr Teresa Dankovich at Carnegie Mellon, bacteria can be reducted by 99.9%.
The paper, printed with food grade ink, is coated with silver nanoparticles which can kill cholera, E Coli and typhoid.
The paper costs pennies to produce and each filter can give up to 30 days of clean water, while each book can allow the user to produce clean drinking water for four years. WATERisLIFE plans to distribute The Drinkable Book in early 2015.
