Cafec 2 Cup Assorted Coffee Filter Paper Pack is made from finest quality paper material. 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 in a consistent speed. No bleach, glues, chemicals or unnatural elements are added to the pulp. This is simply a 100 percent clean, eco-friendly, forest-sustainable coffee filter paper. This allows a smooth water flow and less chances of blockage during coffee brewing. Comes in white colour.
