DESIGN NAME: Sift Filtration System
PRIMARY FUNCTION: Sustainable Filtration System
INSPIRATION: This product was conceived as a solution to the failures of traditional western filters. Current water filtration systems that are sent or donated to developing countries are discarded after they reach their capacity, and end up polluting the same landscape they were intended to assist. Sift filters would eliminate that risk entirely, and when discarded would pose no threat to the environment or anything else.
UNIQUE PROPERTIES / PROJECT DESCRIPTION: Sift filter molds allow people in developing countries to use local resources to create their own water filtration systems. The filters themselves are vessels created from a mix of sawdust and clay; a combination that creates a semi-porous solid wall filter when fired. The molds for these vessels would be sent to potters and artisans in villages in developing areas, allowing them to create their own filters and sell them amongst their wares.
OPERATION / FLOW / INTERACTION: Sift filter molds allow people in developing countries to use local resources to create their own water filtration systems. The filters themselves are vessels created from a mix of sawdust and clay; a combination that creates a semi-porous solid wall filter when fired. The molds for these vessels would be sent to potters and artisans in villages in developing areas, allowing them to create their own filters and sell them amongst their wares. This concept, when paired with vessel designs that are intuitive and understandable, would allow sift to help the 783 million people around the world without access to clean water.
PROJECT DURATION AND LOCATION: This project was started in March of 2017, and was finished late August of the same year.

RESEARCH ABSTRACT: For initial research, the team traveled to Nepal to observe the remote areas of the Gorkha District. Gripped in a deep water crisis, with rising pollution levels and arsenic poisoning, this was the perfect location for research. 3 weeks later, the team had gained ample information regarding water systems to continue forward.
Using information on filter systems from WHO and other sources, 1,000 pages of concepts for filtration solutions were sketched. After the vetting of these ideas, a final concept and material combination for filtration was concepted.
250 of these filters were tested for ergonomics, each time with a different grip variation and slight changes in functionality. After user testing, a final design was created.
CHALLENGE: When the problem of creating a solution to the growing water crisis was approached, one of the biggest issues that faced was reusability. No matter how well the filter was designed or conceptualized, when it reached the end of its lifecycle the filter would be discarded. This would leave the people who once were using it without the means and methods of filtration they had come to know, and could potentially be more harmful than not having it in the first place.
