Diarrheal diseases due to unsanitary water are a leading cause of death in low and middle- income countries. One potential solution to this problem is widespread access to point-of-use ceramic water filters made from universally-available materials. This increased access can be achieved by empowering local artisans to initiate self-sustaining and scalable entrepreneurial ventures in their communities. However, a major barrier to the start-up of these businesses is the prohibitively expensive press used to form the filters. This article reviews filter press technologies and identifies specific functional requirements for a suitable and affordable filter press. Early-stage field-testing results of a proof-of concept design that can be manufactured by two people in two days at one-tenth of the cost of popular filter presses is presented.
