Chemex FSU-100 Pre-Folded Natural Square Filter Papers

The Chemex FSU-100 are the unbleached natural version of the FS-100 square filters - pre-folded, cone-shaped, and designed to fit all Chemex brewers except the 1-3 cup models. Made from unbleached natural paper rather than oxygen-cleansed white paper, they're the more eco-conscious option and fully compostable after use.

Like all Chemex filters, the FSU-100 are made from bonded paper 20-30% thicker than standard pour-over filters, removing bitter oils, sediment, and grounds more effectively and producing the clean, bright cup the Chemex method is known for. Manufactured in the USA from responsibly harvested North American materials and certified to SFI, FSC, and PEFC standards.
