Updated Design

Brews Better

The Kone features a new square-to-round hole design, graduated-density hole pattern and bright polished finish to prevent clogging and facilitate a more even flow of water through your coffee grounds for better extraction and consistent flavor. The updated design more effectively prevents sediment from passing through the filter and optimizes water flow rate whether you're brewing a single cup or larger batch.

New Materials

Easier to Clean

The new bright polished stainless finish and square-to-round hole design traps fewer oils and grounds, and prevents clogging. Constructed from a single piece of stainless steel, the filter has no additional layers or pieces for grounds to become trapped, making it easy to keep the Kone clean and your coffee tasting good.

Stronger Construction

The Most Durable Kone Yet

The high precision seam weld along the side of the filter features twice as many contact points as before, creating a tight, durable seal capable of withstanding serious daily use. The certified food-safe plastic support ring maintains the integrity of the Kone's shape and makes handling safer and easier after you brew.

KONE DETAILS

Designed for Chemex

Compatible with others.

The Kone was designed as an alternative to paper filters for the Chemex, but is also compatible with many drip brewers, including the Ratio Eight, Technivorm Moccamaster, and Bonavita brewers.

NEW: Square-to-Round Holes

Uniform, even extraction.

The new square-to-round hole design minimizes clogging, which in turn prevents channeling of water and dry pockets of grounds, and ensures a uniform flow of water though your grounds.

Photo Chemical Etching

Precision manufacturing.

The Kone's unique hole size, shape and pattern is made possible through photo chemical etching, an incredibly precise manufacturing process that selectively dissolves metal into solution.

NEW: Graduated Hole Pattern

Brew one cup, or more.

The Kone's new, graduated hole pattern transitions from high desity near the bottom to lower density near the top in order to optimize water flow whether you're brewing a single cup or a larger batch.

NEW: Polished Stainless Finish

Easier to keep clean.

The polished stainless finish traps less oil, making it easy to keep clean. And because the Kone is manufactured from a single piece of stainless steel, there is nowhere for grounds to become trapped over time.

Support Ring

Enhanced Durability

The durable, BPA free and food-safe support ring nestles perfectly atop the Chemex, maintains the integrity of the filter's shape after repeated use, and makes the Kone easy to remove after each brew.

Blunt Tip

Safe to Handle.

The Kone's carefully designed, precision welded blunt tip at the bottom of the filter makes handling safe and creates a tight seal with no slits or gaps, ensuring grounds stay inside the filter.
