The original LifeStraw saw no shortage of merited coverage for long after its introduction. A simple device that can inexpensively filter a whole year's worth of water with little chance of failure? What's not to love?
Apparently, the taste of iodine—an unfortunate side-effect of the filtration process. Now a new version almost completely mitigates the iodine aftertaste, making it even more likely that people will use the LifeStraw to clean up their drinking water.
