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.

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.
