Michael Pritchard has invented a water filter system that is inexpensive, easily transportable, and apparently very effective. For those living in developed areas, potable water isn't a daily issue for you. However, in most of the undeveloped world, drinkable water is a matter of life and death. A number of organizations have become involved in sponsoring water wells in various parts of the world. This water filter system should not be over looked if you are interested in helping provide potable water for those that don't have easy access to such.
