Made from unbleached natural paper rather than oxygen-cleansed white paper, they're the more eco-conscious option and fully compostable after use.\u003c\/p\u003e\n\u003cp\u003eLike all Chemex filters, the FSU-100 are made from bonded paper 20-30% thicker than standard pour-over filters. The bonded paper removes bitter oils, sediment, and fine grounds more effectively than a standard filter. That's what gives Chemex its clean, bright signature cup. Manufactured in the USA from responsibly harvested North American materials and certified to SFI, FSC, and PEFC standards.\u003c\/p\u003e\n\u003ch1\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003eQuantity: 100 filters per box\u003c\/li\u003e\n\u003cli\u003eMaterial: Unbleached natural bonded paper\u003c\/li\u003e\n\u003cli\u003eShape: Pre-folded square\u003c\/li\u003e\n\u003cli\u003eMade in: USA\u003c\/li\u003e\n\u003cli\u003eCertifications: SFI, FSC, PEFC\u003c\/li\u003e\n\u003cli\u003eCompostable and biodegradable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eBrewer compatibility\u003c\/h2\u003e\n\u003cp\u003eCompatible with the following Chemex brewers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCM-6A, CM-6GH\u003c\/li\u003e\n\u003cli\u003eCM-8A, CM-8GH\u003c\/li\u003e\n\u003cli\u003eCM-10A, CM-10GH\u003c\/li\u003e\n\u003cli\u003eCM-2 (Handblown 5-cup)\u003c\/li\u003e\n\u003cli\u003eCM-3 (Handblown 8-cup)\u003c\/li\u003e\n\u003cli\u003eCM-4 (Handblown 13-cup)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePlease note these filters do \u003cstrong\u003enot\u003c\/strong\u003e fit the 1-3 cup CM-1C, CM-1GH, or the handblown 3-cup CM-1.\u003c\/p\u003e\n\u003ch1\u003e\u003cstrong\u003eInterested in wholesale?\u003c\/strong\u003e\u003c\/h1\u003e\n\u003cp\u003eOzone Coffee is the official UK importer and distributor of Chemex, offering the full range of brewers and official Chemex filter papers.

The FS-100 is oxygen-cleansed white paper, and the FSU-100 is unbleached natural paper. Choose on colour and processing preference rather than performance, since both filter the same way.\u003c\/dd\u003e\n\u003cdt style=\"margin-top: 24px; margin-bottom: 6px; font-weight: bold; font-style: normal; text-decoration: none;\"\u003eWhich Chemex brewers do these fit?\u003c\/dt\u003e\n\u003cdd style=\"margin: 0 0 20px 0;\"\u003eAll standard and handblown Chemex models from 5 cups upward, including the CM-6A, CM-6GH, CM-8A, CM-8GH, CM-10A, CM-10GH, CM-2, CM-3, and CM-4.

A rinse with hot water clears any trace of paper taste and preheats the Chemex vessel, so your coffee doesn't lose heat to cold glass as soon as it hits the carafe.\u003c\/dd\u003e\n\u003cdt style=\"margin-top: 24px; margin-bottom: 6px; font-weight: bold; font-style: normal; text-decoration: none;\"\u003eAre Chemex FSU-100 filters compostable?\u003c\/dt\u003e\n\u003cdd style=\"margin: 0 0 20px 0;\"\u003eYes. They're unbleached, bonded paper with no chemical treatment, so the used filter and grounds can go straight into your compost bin together.\u003c\/dd\u003e\n\u003cdt style=\"margin-top: 24px; margin-bottom: 6px; font-weight: bold; font-style: normal; text-decoration: none;\"\u003eHow do I fold and place the filter in my Chemex?\u003c\/dt\u003e\n\u003cdd style=\"margin: 0 0 20px 0;\"\u003eOpen the filter into a cone, with three layers of paper sitting against the spout side and one layer against the glass on the opposite side. This keeps the pour spout clear and helps the coffee drain evenly.\u003c\/dd\u003e\n\u003cdt style=\"margin-top: 24px; margin-bottom: 6px; font-weight: bold; font-style: normal; text-decoration: none;\"\u003eWhat grind size works best with Chemex filters?\u003c\/dt\u003e\n\u003cdd style=\"margin: 0 0 20px 0;\"\u003eA medium-coarse grind, similar to coarse sand, suits the thicker Chemex paper and its longer brew time. Too fine and drawdown slows to a crawl, too coarse and extraction runs thin.\u003c\/dd\u003e\n\u003cdt style=\"margin-top: 24px; margin-bottom: 6px; font-weight: bold; font-style: normal; text-decoration: none;\"\u003eCan I use these filters in other pour-over brewers?\u003c\/dt\u003e\n\u003cdd style=\"margin: 0 0 20px 0;\"\u003eThey're cut and folded specifically for the Chemex shape, so they won't sit correctly in a V60, Kalita Wave, or other cone or flat-bottom brewer. Stick to Chemex filters for Chemex brewers.\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"Chemex","offers":[{"title":"Box of 100 Filters","offer_id":43499518591029,"sku":"CHEMEX-FSU-100","price":12.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0023\/1572\/files\/FSU-100_a.png?v=1758555423","url":"https:\/\/ozonecoffee.surf\/products\/chemex-fsu-100","provider":"Ozone Coffee UK","version":"1.0","type":"link"}
