Easy to prep and use, this reusable coffee filter (made with organic USA-grown cotton), compatible with Chemex® coffee makers, is the ultimate solution for the sustainability-minded coffee fiend. Brewing instructions are included in each packet, and Ebb estimates that each filter is good for 90-120 uses: about 3-4 months for a daily coffee drinker, plus it's compostable at the end of its life. Unlike reusable metal filters which let through smaller particles and produce a muddy cup, Ebb's finely woven cotton works as well as or better than a paper filter.
