How A Housewife Invented The Coffee Filter
- Melita Bentz invented a paper-based coffee filter by tearing blotting paper from her son's notebook and placing it over holes in her coffee pot.
- The blotting paper stopped grounds from reaching the cup and let her discard grounds and paper together, reducing cleanup and improving flavor.
Patent Launched A New Filter Product Category
- Melita patented a metal pour-over apparatus in 1908 and sold paired round blotting-paper discs as disposable filter paper.
- The metal reservoir plus tailored paper discs created a new product category that made filtered coffee accessible and repeatable.
Family Startup Grows Through Trade Fair Demos
- Melita and Hugo started the business from home with 50 metal filters and 100 cartons of filter paper and used sons to deliver orders by hand cart.
- Hugo used retail experience and window demos to teach customers how the new product worked, driving early retail adoption after the 1909 Leipzig Trade Fair.
