Chemex-Bonded filters are very important to the fractional extraction process that leaves the coffee fats and bitter elements in the coffee grounds, not in your cup. These unbleached filters are 20-30% heavier that other filters to filter out the sediment. Chemex-Bonded filters combine a very fine grain, required for holding back the coffee mud that promotes the proper infusion. This produces the full-bodied flavorful coffee that is never bitter and has made Chemex is the favorite of coffee connoisseurs for more than 60 years. These filters will not break under the weight of the liquid during filtration or when lifting out the grounds.

Chemex unbleached filters are available in two sizes: one size for the 16 oz. carafe; and one size for the 30, 40, and 50 oz. carafe.
