Description

Our friends at Able Brewing here in Portland invented this excellent metal filter as a reusable solution for Chemex or pour over brewing. Made of laser-welded stainless steel, the KONE allows oils and sediment to pass through, like a French Press, while still allowing the same control and feel of a traditional pour over.

The KONE is compatible with the Chemex Coffee Makers, Origami Pour Over Drippers, and Ratio Eight Coffee Maker.

Need to Know

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.

Able KONE coffee filter

We are still trying to find the right grind to use with it after using paper filters for so long. Too powdery and the grind makes slightly sludgy coffee, too coarse and the water goes through too quickly. But works very well.

I have really appreciated this

I have really appreciated this reusable filter. It is easy to clean, and I can make a quick and easy cup of coffee with it.

Convenient to Use Flow Rate Hard to Manage

Some tips on how to slow down the flow and adjust the grind to match the flow are required. If you pour too fast the pressure causes water to drain around the grounds. Otherwise, I am liking the design of this.

Works great but on my 2nd one in less than a year. Grey plastic/rubber piece underneath the lip pulls away easily after a few months use. Once that's gone the fit is bad. Had to switch to inferior paper filters

Hey Paul,

That totally shouldn't happen, we find that Able's metal filters are generally very durable (we use ours multiple times a day). There's a chance that this could be a manufacturing defect I would suggest contacting Able at info@ablebrewing.com and they'll help you out!

Beautiful and functional but...

I have two of these and they look fantastic and clean up easy. My problem has been the plastic support ring. After about 4 months of use both support rings separated from the filter and eventually fell completely off. I did use them daily but always hand washed them even though they are dishwasher safe. The steel has help up beautifully but unfortunately the same can't be said for the unit as a whole.

Hi there,

Thank you for writing! How long have you had the Kone for? Able has made a few adjustments to keep this from happening. I would reach out to them directly at info@ablebrewing.com as they they support their manufacturer warranty. If you need proof of purchase or have any other questions please let us know!

Ratio KONE filter, a great, quality item

I have used my Ratio KONE every time since I bought it. Paper cones have languished in the box. This is one filter that really does
get the job done. I wish it came standard with my CLIVE coffeemaker and not as an add-on.

Lovely and Functional

Delighted to be able to let go of paper filters, bleached or not. Really enhances the taste of local roast I use. So pleased not taste or use paper. And, of course, I love seeing it on my counter next to my Chemex.
