A Portable water purification tool

LifeStraw is a portable water purification tool that cleanses surface water and makes it safe for human consumption. It is just 25 cm long and 29 mm in diameter and can be hung around the neck, it doesn't require electrical power or spare parts, can filter up to 700 litres of water and effectively removes most of the micro organisms responsible for causing waterborne diseases.
LifeStraw contains a specially developed halogen-based resin, an extraordinarily effective material that kills bacteria on contact. Textile pre-filters are used in the LifeStraw to remove particles up to 15 microns. Active carbon withholds particles such as parasites.
