Cafec have made these filter papers by only using eco-friendly materials, specifically ABACA (Manila Hemp) and Wood pulp sourced from a forestation project. These filters are FSC (Forest Stewardship Council) Certified, They are eco friendly, 100% compostable and Biodegradable. Cafec create these ABACA filters utilising a 'creping' method where folds are formed on both sides of the paper, you can physically feel the folds as the filters surface are textured. This promotes a smooth water flow when brewing and prevents blockages or choking. Abaca+ filter paper is the perfect pour over filter paper for professionals. The roasting level filter paper is designed to control flow speed by the different framework of paper itself, while, the Abaca+ filter paper is designed to create a faster water flow so it is easy for professionals to control water flow by their skilled ability. Abaca+ filter paper not only includes abaca, but also has the FSC certificate. And more, the total volume of package is also decreased by lowering the height of crepe. Then, it will contribute to transportation cost reduction. Abaca+ filter paper is a next-generation product. 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.
