Able Kone Coffee Filter for Original Eight
Able and Ratio have been collaborating on this filter since 2015: a custom version of Able's Kone, designed specifically to extract a full 40-ounce batch on the original Ratio Eight. Able kept refining the design and released a new version in 2020 — it brews better, cleans up easier, and is more durable than the ones before it.
A permanent filter also means the end of the desperate Saturday-morning run for paper filters. Stainless or Black.
