Created by the non-profit WATERisLIFE, The Drinkable Book is a pamphlet designed to teach safe water drinking habits to residents of developing nations. The book is printed on filter paper capable of reducing the bacteria in contaminated water by 99.9-percent, a rate comparable to tap water in the US. The books are inexpensive to produce and can provide safe drinking for one person for up to four years. More information on backing the product can be found on the WATERisLIFE site.
