An air filter arrangement comprises an air channel, a first air filter mounted in the air channel, which first air filter comprises a filter frame provided with at least one passage, and a filter body comprising electrostatically chargeable fibres attached to the filter frame. The filter body extends from the filter frame to a position located at a distance from and downstream the filter frame. The air filter arrangement comprises a second air filter comprising a filter cloth which, in a mounted state, is adapted to extend across the air channel such that it is flown through by air flowing in a substantial longitudinal direction in the air channel, and that the second air filter is mounted in the air channel in a position located downstream the first air filter with respect to the flow direction of the air through the air channel. |
