摘要： A filtering device intended to be attached temporarily to an exhaust pipe (30) of a vehicle at occasional indoors driving and the like. The device comprises a filter (14), a filter holder (11) and a connection member (13,40) for attachment to the exhaust pipe. The object is to provide an exhaust filter which is simple to mount and dismount, which is self-supporting, which can be manufactured so cheap that it can be used as a disposable article, and which gives possibility of choice regarding the connection to different dimensions of exhaust pipes. These objects have been solved by the fact that the filter holder (11) consists of a double-sided open sleeve (15), both ends of which are designed with coupling means (16, 17), for example in the form of a bayonet complings, for connection of a perforated cover (12) attachable at one end of the sleeve and provided with corresponding coupling means, said cover being intended for inclusion of said filter (14) which is locatable against a seat (22) in the sleeve, and that to the other end of the sleeve (15) there are connectible alternative connection members (13, 40) for attachment to exhaust pipe (30) with different diameters, and which connection member is arranged in the axial extension of the sleeve and designed to support the holder (11).
