The water crisis is so far reaching that it's just not possible to dig a well and get clean water to everyone who needs it. At least not all at the same moment. The pipe filter is a low-cost solution that allows people to drink from contaminated water sources without getting sick. Using a pipe filter, you can avoid guinea worm and other diseases.
Life Straw is one of the pipe filters that's being widely distributed to people who can't get clean water. It has been hailed as an innovation of the year, perhaps the century. Check out how it works. You can also find out how to use it at Point of Use Technologies, an organization that promotes the use of products that reduce illness without requiring infrastructure.
