Why did Melitta bentz invent a coffee filter?

At the time, coffee was typically brewed using a metal filter, which allowed grounds and sediment to pass through into the cup. Bentz found this to be unpleasant, so she experimented with different materials to find a way to remove the grounds without affecting the flavor of the coffee.

She eventually settled on using blotting paper, which she cut into circles and placed in a metal funnel. This simple design proved to be very effective, and it quickly became the standard for coffee brewing.

Bentz's invention was a major breakthrough in coffee preparation, and it has had a lasting impact on the way we enjoy coffee today. Her coffee filter is still used by millions of people around the world, and it continues to be the preferred method for brewing a smooth, delicious cup of coffee.
