CHEMEX BONDED FILTERS PRE-FOLDED 100 SQUARES PER BOX (FS-100)

Chemex filters are engineered to capture even ultra-fine sediment along with excess oils and lipids that can muddy the cup. Their design controls flow rate to maintain an optimal extraction window—never dragging, never rushing. This balanced infusion allows the grounds to fully saturate (similar to steeping tea), resulting in a more developed, nuanced flavor while selectively filtering out compounds that contribute to harshness and bitterness.

Formed into a precise cone—much like laboratory filtration methods—the filter promotes even water distribution through the entire coffee bed. As water travels uniformly toward the tip, it ensures consistent extraction across all grounds. The construction is also highly durable, preventing tearing under liquid weight and holding up when removing spent grounds.

The result is a cleaner, fuller cup with greater flavor clarity—using less coffee, achieving the strength you want, without the bitterness.

About the Brand

Chemex Coffeemakers have been a design icon since 1941, created by a chemist who sought a brewer that was simple, elegant, and made from pure, non-porous glass. Remarkably unchanged for over 70 years, the Chemex - paired with its proprietary filter - produces coffee that’s clean, flavorful, and free of bitterness or sediment.
