Able KONE Coffee Filter

The Able KONE is a reusable stainless steel filter designed to replace paper filters in your Chemex or compatible pour over dripper. Its photochemically etched holes allow water to flow evenly through the entire coffee bed — not just the bottom — delivering balanced extraction and a fuller-bodied cup without the waste of disposable filters.

Key Features

• Photochemically etched stainless steel with dual-sided holes (round on one side, square on the other) to prevent clogging
• Fits standard Chemex brewers and most cone-shaped pour over drippers
• Ratio Eight version available with additional holes for higher brew volumes (up to 40 oz)
• Allows coffee oils and fine sediment to pass through for richer mouthfeel than paper, cleaner than typical mesh filters
• Designed in Portland, Oregon; assembled in China
• Eliminates paper filter waste and recurring costs

The KONE delivers a unique pour over experience that bridges the clarity of paper-filtered coffee with the body of French press. Whether you're brewing on a Chemex at home or integrating it with your Ratio Eight, Clive offers the tools, support, and education to help you master every pour.
