An oil mist filter is fixed on an air intake of an oil mist collector and contains: a top cover, a bottom cover, and a conical filtering assembly. The top cover includes a collection portion formed on a central position thereof and a plurality of guiding portions radially extending outward from the collection portion. The bottom cover is hollow and includes a through orifice defined on a central position thereof, and an outer diameter of the bottom cover is greater than the top cover. The filtering assembly is disposed between the top cover and the bottom cover. Thereby, oily substances from the top cover are guided by the plurality of guiding portions to flow through and to be filtered by the filtering assembly, and then the oily substances are guided out of the through orifice of the bottom cover.
