In this case, you can go ahead and judge a book by its cover.
Across the globe, 3.4 million people die each year from water-related diseases. The statistic is particularly staggering considering that many people at risk of such preventable deaths have no idea that the water they imbibe is contaminated.
To educate people about the need to filter water, and to provide the tool to do so, WATERisLIFE teamed up with researchers from Carnegie Mellon and the University of Virginia to develop the Drinkable Book.
Costing just pennies to produce, the innovative book both teaches water hygiene (i.e. keeping trash and feces away from water sources) and serves as a filter that kills deadly bacteria.
The book functions much like a scientific coffee filter. When water passes through it, more than 99 percent of the harmful bacteria are killed, making it comparable to the tap water in the U.S.
