More than 40% of the people who live in Yemen don't have access to clean drinking water. People often use scarves to filter out large pieces of debris, without realizing that the real dangers in the water slip right through. Those are the microbes that cause debilitating diarrhea.
The Silver Filter Company recently introduced silver-clay filters that kill microbes. The filters sort of look like clay pots you'd use for planting. They are that simple. Yet the silver kills the microbes in the water on contact. (Small amounts of silver are used; they don't affect health.) These filters are improving lives for children and adults alike.
