The Curtis Coffee Filter GEM-6-101 are made using a no-bleach process and made to be used with Wilbur Curtis Coffee brewers. The paper filters have fluted side to avoid collapse, and the porousness is designed to hold the hot water for the correct amount of time in the brew cone in order to extract maximum flavor without bitterness.
