Melitta (//) is a German company selling coffee, paper coffee filters, and coffee makers, part of the Melitta Group, which has branches in other countries. The company is headquartered in Minden, North Rhine-Westphalia.
It is named after Melitta Bentz (1873–1950) who founded the company after she invented the drip brew paper coffee filter (German patent granted July 8, 1908). Bentz later ran the company as a family business.
In 1908, Melitta Bentz, a 35-year-old woman from Dresden, Germany, invented the first coffee filter, receiving a patent registration for her "Filter Top Device lined with Filter Paper" from the Patent Office in Berlin on July 8. She founded the company bearing her name the same year.
In the 1930s, Melitta revised the original filter, tapering it into the shape of a cone and adding ribs. This created a larger filtration area, allowing for improved extraction of the ground coffee. In 1936, the widely recognised cone-shaped filter paper that fit inside the tapered filter top was introduced. The '102' became the most popular.
Melitta continued to develop new techniques to improve the shape, performance, material and production process of its filter systems. In 1989, Natural Brown coffee filters made from unbleached pulp were introduced, which kept unwanted by-products from leaching into the environment. In 1992 Melitta developed an oxygen-bleaching process to produce white paper without chlorine. In 1997, Melitta developed a filter with Flavor Pores, microfine perforations that filter out unwanted sediment, particles and oils[clarification needed]. In 2002 Melitta added a second safety crimp to increase strength and durability. In 2007 bamboo Filters were introduced and the Flavor Pores filter was improved.
As of 2015[update] Melitta Group KG employed 3,300 people.
Melitta USA, headquartered in Clearwater, Florida, is part of the privately held Melitta Group of Minden, Germany. Melitta USA is responsible for the sales and marketing of Melitta coffee filters, coffee, and non electric coffee systems in the USA.
