The natural brew story: after more than 20 years in the coffee business, two things still bothered me. One, Coffee filters were bleached with white chemicals, and two, They were very hard to separate. Then, a few years ago, I began working with one of America's most respected Coffee producers to develop a new kind of filter. A natural Brown filter that hasn't been bleached white. Since they are made with only the finest of papers, they're easy to separate. The end of Two of life's little frustrations. So there you have it. The new Brown filter We call natural brew. These filters have countless other great uses including: serving snacks, craft projects, cleaning windows and glassware, and more!
