Design and development of grey water filter that can outperform the existing ones formed the objective of this study. Making available reusable water from grey water is not only essential for improving the living standard of the populace but timely because of its contributions to the development and well-being of the masses. In this study, activated carbon was adopted in the place of piece of cloth for filtration of water, and to reduce the weight and make it more portable, lightweight materials were adopted. To optimize the filtration efficiency, multiple filters with varying pores were adopted in the design. The result showed that the developed filter device possessed higher filtering rating than the existing concepts.
