Chemex Funnex

CHEMEX® Funnex® Pour-Over Coffeemaker

Great coffee should fit wherever your day takes you. The CHEMEX® Funnex® is a compact single-cup pour-over brewer that brings the clean, clear flavor of CHEMEX coffee to your favorite mug, travel tumbler, or thermos.

Made from double-walled borosilicate glass, it is designed for everyday brewing at home, at work, in a dorm, or wherever a proper coffee break is needed. Brew a small 5-ounce cup or make up to 15 ounces for a longer, slower morning.

One Brewer, Anywhere

The Funnex® sits directly on top of a cup, mug, or thermos using its included silicone brewing gasket. The gasket provides a stable base while allowing the brewer to fit a variety of vessels—so there is no need for a dedicated carafe or bulky coffee setup.
