A custom made reusable metal filter for the Ratio Eight. We collaborated with Able Brewing to create a filter that ideally extracts the flavors from your coffee for larger batch brews. The Kone is manufactured in the USA of high quality steel that is photo-chemically etched with a precise array of holes. The quantity, size, and distribution of holes is a proprietary design that produces a very smooth extraction with little sediment.
