Coffee filter paper

Coffee filter paper is a specially designed, thin, and porous paper used to separate ground coffee from liquid water during brewing. Its consistent porosity allows water to flow through while trapping coffee grounds, resulting in a clear, sediment-free brew. Made from cellulose fibers, it is typically disposable and biodegradable. The paper's uniform structure ensures smooth extraction of flavors without impeding flow, making it an essential component of drip coffee makers and pour-over methods. Overall, it provides an efficient, clean way to extract coffee essence while keeping fine grounds out of the final cup.
