The LifeStraw is a water filter designed to be used by one person to filter water for drinking. It filters a maximum of 1000 litres of water, enough for one person for one year. It removes almost all of waterborne bacteria and parasites. In addition to the classic LifeStraw, the manufacturer also produces other styles on the LifeStraw product: the LifeStraw Family, a larger unit designed for family use, and the LifeStraw Go Water Bottle, which incorporates a LifeStraw filter into a plastic sports water bottle.
The LifeStraw water filters are designed by the Swiss-based Vestergaard Frandsen. While originally developed for people living in developing nations and for distribution in humanitarian crisis, the LifeStraw has gained popularity as a consumer product. The LifeStraw is now used as a tool for survivalists and packed in emergency preparedness kits in addition to being used to help combat clean water scarcity worldwide. LifeStraw personal filters can provide clean water for up to a year, and the LifeStraw Family filters a maximum of 18,000 litres of water, providing safe drinking water for a family of five for up to three years.
LifeStraw and LifeStraw Family were distributed in the 2010 Haiti earthquake, 2010 Pakistan floods, 2011 Thailand floods, and 2016 Ecuador earthquake, among other crises and initiatives. In the Mutomo District in Kenya which has suffered from long term drought, the Kenya Red Cross supplied filters to 3,750 school children and 6,750 households. In 2015, LifeStraw filters were deployed in Rwanda.
