The Able Kone coffee filter is the 3rd generation with many upgraded features. It’s a reusable filter designed to be used with the Chemex brewing system, the Kone brewing system and similar larger types of round filter pour-over brewers. This filter excels because it allows more oils and a richer, fuller bodied cup of coffee compared to those brewed with paper filters. It’s also reusable, which equals less waste (and mess!). All it takes is a quick rinse under hot water to keep the smooth stainless steel filter clean.
