Water filtering is one way of purifying water it may be a rain water , water from a water pump or deep well and tap water. Why filtering? Diarrhea, gastro enteritis diseases , typhoid fever and other waterborne diseases are the causes of death among children and adult are alike . Based on the research of the World Health Organization’s every year more than 3.4 Million dies as a result of waterborne diseases and death around the world (http://www.voanews.com)
In a place where there is no pollution rain water is clean enough as a source of drinking water ( TAO Workshop, 2008) and rainwater harvesting is a safe sustainable water source( Rainwater Harvesting, 2008) . Rain harvesting is common for those villages that have no water available in their community. However, rainwater is now saturated with pollution coming from factory , CFC , smoke belching and other sources of pollutants , so people use water filter to harvest the rain.
Usually people use machine to filter water, however in a place where life is simple we do require an innovation and improvised materials. How we can filter water in a simple way?. The above illustration shows us how.
On the other hand filtering can remove the visible bugs but the invisible bugs remain. After filtering it is recommended to purify the water using a number of methods, like boiling and bleaching treatment.(www.wilderness-survival-skills.com) .
Boiling is reaching the 100 degree Celsius boiling point, and bleaching treatment; add two(2) drops of household bleach per quarter per liter for clean looking water . Add four (4) drops of household bleach per quarter on not clear looking water.(Ibid)

Safe drinking water is the sum of filtering and purifying” (Brian, 2003)".Sources:
