Filter for separating substances having lipophilic and/or oleophilic and/or apolar properties from different liquids, gases and vapors

A filter for separating substances having lipophilic and/or oleophilic and/or apolar properties, such as fats, oils, substituted or unsubstituted hydrocarbons, from different liquids, gases and vapors, such as water, (moist) air and water vapor, employing polyolefin fibers and/or filaments which have a diameter of 0.1 to 10 82 m, and preferably 0.5 to 2 mu m, as filter material. The filter material is present in the form of bands or strands which are of finite or infinite length, and which are formed from webs, waddings or other sheet-like structures made of such fine fibers and/or filaments and which are arranged with respect to each other in such a way that free openings and passages are in between them. The filter material perferably consists of polyethylene and/or polypropylene fibers and/or filaments.
