No Paper Filter Fuss

The Kone brews a full-bodied cup of coffee, rich with oils and flavors normally trapped by paper filtration, and doesn’t impart unwanted flavors. And unlike paper filters, the Kone produces no paper waste. Simply rinse and repeat.

Meticulously Engineered

Every last detail of the Kone has been painstakingly engineered to help you brew a delicious cup of coffee. Its singular design and unique features facilitate an even, controlled flow of water through the coffee grounds for better extraction and consistent flavor.

Built to Last

Constructed from a single piece of precision-welded, photo chemically etched stainless steel and an injection-molded, food-safe polymer support ring, the Kone is built to stand up to the daily demands of the cafe and your home.

Easy to Clean

A quick rinse and occasional scrub keeps the Kone in tip-top shape. Unlike other reusable filters made with cloth, mesh, and gimmicky construction, the Kone’s elegant, single-layer design prevents build up of oils and sediment.

Available in Black Titanium

Kone is now available in a stunning, black titanium-coated stainless steel with black polymer support ring. Works with Chemex and with Ratio's new Glass Carafe in Smoke Grey.

Kone Details

Made for Chemex

Kone was designed to nestle perfectly atop your Chemex coffee maker for a perfect fit.

Square-to-Round Hole Design

Photo chemically etched square-to-round hole design reduces clogging and creates an even flow of water through your grounds.

Graduated Density Hole Pattern

Kone's unique hole pattern optimizes water flow rate for both smaller brews and larger batches.

Polished Stainless Steel

Bright polished stainless steel imparts no unwanted flavor, and prevents build up of coffee oils that can become rancid and bitter.

Blunt Safety Tip

Precision-welded blunt tip makes handling safe and creates a tight seal with no slits or gaps.

Durable Support Ring

Durable support ring nestles perfectly atop your Hario V60 dripper and makes it easy to remove after each brew.
