The Chemex filter coffee device was invented in 1941 by Dr. Peter Schlumbohm. The design was based on the experience of this talented chemist. This hourglass-shaped one-piece container is made of high-quality heat-resistant glass. Its iconic part is the wood and leather covering around the narrowing neck, which prevents the hot glass from causing injury. Unpleasant odors do not stick to the glass, so previously prepared coffees do not affect the taste of freshly brewed coffee.
