Great Filters!

Ratio does an incredible job designing their coffee machines, and the same can be said about their paper filters. These have worked great in brewing a clean and tasty cup every single time.

The Ratio 6 makes fine cups of coffee quickly, efficiently, correctly. The thermal carafe keeps the brew hot. I roast my own beans so I have the freshest coffee possible. The Ratio 6, a terrific investment, does justice to my coffee.
