The invention relates to an ultrasonic gas filter device and method based on a wet surface. The ultrasonic gas filter device comprises a machine shell, a fan, an exhaust pipe, an inlet gas accelerating pipeline, a filter cavity, a filter sticky wall, an ultrasonic generator, cleaning fluid and the like, the ultrasonic generator generates atomized liquid to wet the filter sticky wall and comprehensively wrap around sucked polluted particles, the polluted particles are adsorbed on the filter stick wall, air treated by the one-stage or multi-stage filter cavity reaches the direct emission standard, and the interior of the device can be structurally and automatically cleaned through the ultrasonic cavitation effect and the cleaning fluid. The gas filter device and method have the advantages that oil smoke, dust and other pollutants in the air are effectively adsorbed and filtered, the filtered air is directly discharged indoors, a pipeline is not required to be laid, the device is clean and environmentally-friend
