The filter can be used with 12-cup-capacity commercial brewers. It is made from paper that has been processed using an elemental chlorine-free (ECF) bleaching method to ensure that there is no detectable level of dioxin. The widest part of the filter measures 9-3/4″ in diameter, and the base of the filter measures 4-1/4″ in diameter.
