The LifeSaver bottle is a portable water purification device. The bottle filters out objects larger than 15 nanometres. After the 2004 Asian tsunami and Hurricane Katrina disaster in the U.S., Michael Pritchard, a water-treatment expert in Ipswich, England began to develop the LifeSaver bottle after seeing that it took multiple days for water to reach refugees.

Pritchard's entire stock of 1,000 bottles sold out within four hours of the presentation. More information...
