These aren't your standard paper filters. Chemex filters are made from laboratory-grade paper and bonded for extra thickness—they're 20-30% heavier than typical coffee filters. That extra weight does important work: it catches the fine oils and sediments that can cloud flavor or add unwanted bitterness, resulting in an exceptionally clean cup that showcases the coffee's inherent character.

The thickness also controls extraction time. Too thin and water rushes through, under-extracting the coffee. Too thick and it over-extracts, pulling harsh flavors. Chemex filters hit the sweet spot—allowing enough contact time for full flavor development without tipping into bitterness.

If you're brewing our single origins or lighter roasts like Brunch, these filters become particularly valuable. They let the delicate citrus notes, floral aromatics, and subtle fruit flavors come through with clarity that other brewing methods might muddy.
