These filters from Cafec are designed specifically for the medium-sized Origami dripper, and they are a great alternative to other cone-shaped filters like the Hario V60-02 filters. Made from virgin pulp, a naturally cleaner material than what is found is most other filters, these allow for cleaner coffee brews. The lack of ridges inside the filter also ensure that you don't end up losing coffee grounds to the walls of your brewer.
