A large percentage of the world’s population does not have regular access to clean drinking water. Now there’s a possible solution; a personal water-filtering device called LifeStrawR. At about 12 inches in length. 1.2 inches in diameter and weighing less than two ounces, LifeStraw looks like a big fat drinking straw. But this “straw” removes nearly all bacteria, viruses, parasites, and even dirt from virtually any water supply. The device relies solely on the sucking action of the user to draw water through special filters. It’s effective for about 1,000 liters of water.
Currently, most LifeStraws are distributed through international aid agencies to people in poor countries who do not have access to clean water. There have been criticisms that the device is still a little too expensive for its intended market, but that may change over time, especially if similar devices eventually come on the market. In the U.S., LifeStraw is available only through several online sellers.
Disclaimer: I do not have a financial interest in LifeStraw. I just think it’s a clever solution to a worldwide public health problem.
