These oxygen cleansed (not bleached!), pre-folded filter circles are an essential part of brewing coffee with a Chemex. They are heavier than other brands and trap all the grounds from the coarsest particles to the finest fines. The resulting cup surpasses all others in terms of flavor and clarity. Chemex filters are guaranteed not to burst under the weight of the liquid during filtration, and not to break when lifting out the grounds.
Half-moon filters are for 3-cup coffeemakers.
One box contains 100 filters for both filters.
