The Cafec Filter Paper is produced to bring out the best in your coffee. CAFEC filter paper has “Two-Side Crepe” developed by their original paper making technology (Air-through dry). Due to the balance of the height of the crepe on both sides, it can keep an air layer between paper and dripper so water can flow at a consistent speed. No bleach, glues, chemicals or unnatural elements are added to the pulp. This is simply a 100% clean, eco-friendly, forest-sustainable coffee filter paper. This allows a smooth water flow and less chances of blockage during coffee brewing. Perfect for use with the Cafec 1 Cup Flower Dripper and Hario V60 01 Drippers.
