Description The formulation of Chemex filters permits the proper infusion time by regulating the filtration rate—not too slow, not too fast. Good infusion of the grounds imparts a richer flavor and filters out undesirable oils and compounds that can make coffee bitter. The Chemex half-moon filter is easy to fold into a cone shape. This shape assures uniform extraction because the water filters through all of the grounds on its way to the apex of the cone. Chemex filters are guaranteed not to break under normal brewing circumstances. Fits Chemex 3-cup coffeemakers. Must be hand-folded prior to use.
