LifeStraw® was invented by the Swiss-based company Vestergaard in 2005 and since the technology has been deployed to almost every major natural disaster. LifeStraw® Personal is the award-winning water filter appointed "Best Invention of the Year" by Time Magazine, that enables users safely to drink water from contaminated water sources. The LifeStraw® Personal Water Filter filters up to 1,000 liters of contaminated water and contains none chemicals, batteries or moving parts as many other water filters on the market. Place the LifeStraw® directly in the contaminated water and you can immediately drink. It's ideal for hiking, backpacking, camping, travel, and emergency preparedness.
