The Chemex coffeemaker---invented in 1941---is well-respected amongst coffee enthusiasts. Its iconic design has made it's way into the permanent collections of museums such as the Museum of Modern Art and the Smithsonian. However, where it really earns praise with its users is in the fact that it brews---by way of Chemex's 4-ply filters---one of the "cleanest" cups you'll ever have, allowing the pure flavor of the particular coffee to shine.
