It is a major issue in many developing countries and hurricane-torn zones. As a survey of the potable water that most rural houses showed, we appalled at the quality and decided to do something about it. This design devised an ingenious filter container with bilayer structure that is aimed at being a low cost water treatment washing container optimally suited to rural conditions. The filter element is filled with water to be filtered, the water then saturates the bilayer and slowly filters through the pores at a certain rate, provided the washing container is kept full.
