The invention relates to an ecological type air purifier which comprises a box body, a spray point, a high-voltage electrostatic generator, a fan and a circulating water pump. The ecological type air purifier is characterized in that an air inlet and an air outlet are formed in the box body; a spraying water pipe is arranged on the upper portion of a spraying water box; the spray point is arranged on the portion, on the inner side of the air inlet, of the interior of the box body; a water tank is arranged at the bottom of the box body and connected with the circulating water pump; the output end of the circulating water pump is connected with the spraying water pipe; a water baffle is arranged above the spray point. The ecological type air purifier has the advantages that the theory that ozone can be dissolved in water is utilized to eliminate a co-product, namely ozone, during electrostatic dust collection, and due to the fact that secondary pollution is prevented when the water absorbs the ozone, the ecological type air purifier meets the environment protection requirements.
