Pocket-sized Arsenic Filter to Purify Drinking Water

According to an InvenTeam student presenter, "Arsenic causes an estimation of 25,000 deaths in Bangladesh." The InvenTeam calls its filtering process the KOOL-AID® effect, because the media pills turn the water red when it extracts the arsenic. The red water then passes through a small filter, which screws into the bottle opening, making the water clear. The filters can be used up to ten times, and the filter system costs only five cents. This portable device can be carried in a person's pocket and fits on any two-liter water bottle. A Baptist-youth group organizer successfully tested the filter system in Nepal.
