A water-filtering straw

The LifeStraw filter removes 99.9% of bacteria and 96.2% of viruses. It was initially created for those in emergency conditions and for people living in developing countries without enough fresh clean water. However, this device became very popular among world travelers. You can use this device to drink water from a river or a lake. It can be useful when you are not sure of the quality of the water you are drinking.
