One of the most innovative and useful products by mankind for mankind. Designed by the Swiss-based Vestergaard Frandsen, the lifestraw is a handy water-filter that looks like nothing less than a chic water bottle and can always squeeze itself into a handbag or backpack. You have to slightly dip the lifestraw in water and sip like you would from a straw. It purifies the water 98.9% of many waterborne protozoan parasites before it can even reach your lips from the water surface. Not just the microbes but all the chemicals, dust and heavy metals are retained by this filter. Each product can filter 1000 litres of water per year, which is adequate for one person. It lets you drink filtered, crispy water no matter where you source it from. The water that enters the tube passes through hollow fibres which purify it. It operates based on physical filtration alone and uses no chemicals. The water is driven upward by the power of suction, similar to the pull in a normal straw.
Originally targetted for helping out the developing nations and in managing disasters, the Lifestraw is now becoming popular as a consumer product in all spheres ranging from hiking, camping and rural visits. This product is now increasingly reserving its place in emergency prepardness kits and survival kits. It goes on to limit drinking water scarcity worldwide without even having to consume electricity. While a personal Lifestraw product can filter water for a person throughout an year, the Lifestraw family can filter upto 18000 litres or 4755 gallons of water in its lifetime, thereby providing a family with clean drinking water for upto a maximum of 5 years. These two products were distributed during the following calamities-
* Pakistan floods (2010)
* Haiti earthquake (2010)
* Thailand floods (2011)
* Ecuador earthquake (2016)
