: 140– She wanted to remove the bitter taste caused by overbrewing. On 8 July 1908, the first commercial paper coffee filter was devised by the German entrepreneur Melitta Bentz. In 1894, the Wilda'sche coffee filter device by Eugen Wilda used single-use cloth filter bags, which, in the corresponding patent, were considered to be superior to paper filter bags presumably already in use at the time. In 1885, Heinrich Böhnke-Reich (aka Boehnke-Reich) warned of using old wall paper as coffee filters, but favourably described sheets of thick wool-style greyish paper which could be cut into shape for use as quick filters in a conical filter holder. In 1847, Elard Romershausen (aka Elard Römershausen and Elard Rommershausen) experimented with paper filters while constructing an early "air press coffee machine". : 63–64 Hamburg filters made out of (enameled) metal or porcelain were still very common in the 1900s in Germany. : 139 In 1785, a silver filter was manufactured by Johann Christopher Hellmers, suggesting that porcelain versions existed even earlier. In Germany, filter paper inserts were used in narrow conical metal filter holders called " Hamburger Spitztrichter" (Hamburg filter) to extract drip coffee. In 1782, Johann Georg Krünitz described a then-new method to extract coffee utilizing blotting paper in a (tinned) metal filter cone. Main article: Filter paper History of paper filters Since paper filters filter out some components the resulting coffee is said to taste somewhat fruitier compared to permanent filters.įor a filter to be compatible with a filter holder (in the case of drip coffee preparation also called a dripper) or coffee maker, the filter needs to be a specific shape and size. Some baristas claim that paper filters exhibit a "paperish" taste and recommend to wash out the filter with a flush of hot water before filling the ground coffee into the filter. Typically, coffee filters are made up of filaments approximately 20 micrometres wide, which allow particles through that are less than approximately 10 to 15 micrometres. Both bleached and unbleached filters are made. The raw materials ( pulp) for the filter paper are coarse long fiber, often from fast-growing trees, i.e Melitta uses up to 60% of bambus in their filters since 1998. Ĭoffee filters of paper are made from about 100 g/m 2 filter paper. Several studies indicate that the mild consumption of paper-filtered coffee may reduce the risk of coronary heart disease. Metal, nylon or porcelain mesh filters do not remove these components. Paper filters remove oily components called diterpenes (like cafestol and kahweol) these organic compounds, present in unfiltered coffee, have anti-inflammatory properties.
