Paper filters designed for cone shaped drippers such as the Cafec Flower Dripper, Hario V60, etc.
These filters are made of a non-wood material called ABACA (Manila Hemp). This fibre is very strong and as a result the filters are half the thickness, yet four times as strong as normal wood pulp filters. The plant itself is also much faster growing. They also carry FSC (Forestry Stewardship Council) certification thanks to their lower environmental impact.
