No filter bag needed for this coffee maker. The Cafino has a double stainless steel mesh sieve that fits into a heat resistant borosilicate glass cylinder. Simply place your ground coffee beans into the sieve, pour boiled water, and voilà, you have coffee. It’s quite similar to the metal Kone Coffee Filter used with the Chemex Coffeemaker, yet in a more familiar coffee press silhouette.
