Sift

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.
