Chemex filters remove even the finest sediment particles as well as the undesirable oils and fats. The formulation of the filter permits the proper infusion time by regulating the filtration rate - not to slow, not too fast. Good infusion of the coffee grounds (as in brewing and steeping tea) gives coffee a richer flavor while at the same time making possible precise fractional extraction: filtering out the undesirable components which make coffee bitter by allowing only the desirable flavor elements of the coffee bean to pass through. The Chemex filter is guaranteed not to burst under the weight of the liquid during filtration, and not to break when lifting out the grounds. Fully-bodied, richer flavor, from less coffee, and as strong as you like without bitterness.

• Thicker (20-30% more than the competition) specialty fiber filter design keep bitter;
• Elements, oils, and grounds in their place (and out of your cup)
• Prefolded for convenience
• Will fit most other cone-shaped filter coffeemaker
