This solution works because it's simple, effective, and lasts a really long time.
The HydrAid™ Water Filter encloses four layers of sand, gravel and a biological surface layer where bacteria consume the microorganisms and pathogens to clean the water.
The water is poured into the top of the HydrAid™ filter as needed, first through the biological layer, then down through the additional layers of sand and gravel. As the water collects at the base of the filter, the water flows by gravity out of the filter through plastic piping attached at the unit's exterior.
The HydrAid™ filter can meet all of a family's water needs, including drinking, bathing and washing

Previously used BioSand Water Filter designs have used manual concrete construction techniques that resulted in a heavy 300 pound end product that was difficult to transport, inconsistent in quality, and incompatible to scale for market needs. In contrast, International Aid's plastic HydrAid™ filter weighs about 8 pounds, is easily transported in large quantities and is inexpensive and scalable.
