More than one billion people – one sixth of the world’s population - are without access to safe water supply. So one sixth of the world's population is suffering from waterborne diseases, of which over 6,000 – mainly children – die each day by consuming unsafe drinking water.
A product called "LifeStraw" was developed as a practical response to the billions of people who are still without access to a clean water supply. A LifeStraw is a personal, low-cost water purification tool with a life time of 700 litres – approximately one year of water consumption for one person. At less than 10 inches long, the device can filter up to 185 gallons (700 liters) of water at a low cost of no more than a couple of dollars. The device will kill 100% of bacteria and 99% of viruses in water that passes through it. The device filters water teeming with typhoid-, cholera- and diarrhea-causing microorganisms drinkable, but the device does not filter heavy metals such as iron or fluoride nor does it remove parasites like cryptosporidium or giardia.
The "LifeStraw" device is made of halogenated resin, one-micron filtration wool, and a charcoal filter to reduce odor, chlorine, asbestos, herbicides, and other undesirable properties.
