Abstract

The invention relates to an air-cleaning filter of the type that comprises a set of soft threads (4) of an electrostatically chargeable material and a thread-carrying body (3), having a round basic shape, which comprises gaps (6) defined by curve-shaped walls (5) through which air may pass into and through the thread set. According to the invention, gaps (6) located near the periphery of the body are thinner than gaps located closer to the centre of the body. In this way, an even distribution of the threads in the thread set is obtained.
