The Origami Pour-Over Coffee Dripper is an eminently versatile pour-over brewer that is compatible with both conical and wave filters. These particular wave filters are made by Origami itself. Like all paper filters, these filter out most coffee oils and unwanted particles, resulting in a clean, clear cup of coffee. Moreover, like other flat-bottomed filters, these promote a more even coffee bed for your brew water to pass through than a conical filter might, resulting in more even extraction. While these are Origami’s own filters, they’re still compatible with other flat-bottomed coffee drippers, like the Kalita Wave and the Simplify Brewer.
