The disclosure herein describes an air-cleaning apparatus which comprises a frame support in the form of a rectangular hollow body including a first lateral wall having an inlet adapted for receiving exhaust and a second lateral wall opposite to the first lateral wall having an outlet for expelling cleaned exhaust; at least one filtering member removably inserted between the first and second lateral walls, which has a plurality of suitably dimensioned perforations formed therein, means for supplying a cleaning liquid, said means enabling said cleaning liquid to flow against said filtering member and spread over said perforations; and means for collecting said cleaning liquid. When a stream of the cleaning liquid is spread over the filtering member, a liquid film is effectively formed on the perforations therein, which will efficiently remove any pollutants existing in the exhaust so as to prevent air pollution from resulting therefrom.
