The Chemex FS-100 are pre-folded square filters designed to fit all Chemex brewers except the 3-cup models. Like all Chemex filters, they're made from bonded paper 20-30% thicker than standard pour-over filters, which slows the flow rate and removes bitter oils and sediment more effectively - producing the clean, bright cup the Chemex method is known for. Oxygen-cleansed and bleach-free, they impart no unwanted flavour to your brew. Manufactured in the USA from responsibly harvested North American materials and certified to SFI, FSC, and PEFC standards. Compostable after use.
The square pre-folded design differs from the FC-100 circle filters - both work across the same range of Chemex brewers, so choice between them comes down to personal preference. If you're unsure which to order, the FS-100 squares are slightly easier to open and seat in the brewer for some people.
