The “drinkable book” contains tear-out pages, each one nanoparticles of silver or copper. As bacteria move through the paper filter, they absorb some of these nanoparticles, which leads to their death. These pages can kill 99.9% of harmful bacteria in the water.

A single sheet of paper can purify up to 26 gallons of water, and a single book can supply a person’s water needs for up to four years.

The filter book is inexpensive, easy to use, and can be used to distribute information along with the materials.
