Coffee filter
coffee-brewing utensil, usually made of disposable paper
A coffee filter is a filter used for various coffee brewing methods including but not limited to drip coffee filtering. Filters made of paper (disposable), cloth (reusable), or plastic, metal or porcelain (permanent) are used. Paper and cloth filters require the use of some kind of filter holder, whereas filters made out of other materials may present an integral part of the holder or not, depending on construction. The filter allows the liquid coffee to flow through, but traps the coffee grounds.
Overview
Paper filters remove oily components called diterpenes (like cafestol and kahweol). Metal, nylon or porcelain mesh filters do not remove these components. These organic compounds, present in unfiltered coffee, have anti-inflammatory properties. Several studies also indicate that the mild consumption of paper-filtered coffee may reduce the risk of coronary heart disease due to reducing these compounds.
Coffee filters of paper are made from about 100 g/m2 filter paper. The raw materials (pulp) for the filter paper are coarse long fiber, often from fast-growing trees, e.g.

“Coffee filter” is worth following because a concise public description often conceals a longer documentary argument. Here, Coffee, filter and coffee-brewing provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q1541241. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
