The utility model discloses a movable type air purifier for a tent. A draught fan, a high-voltage electrostatic adsorption device and efficient active carbon filters are sequentially arranged in a shell from bottom to top. An air inlet is formed in the position, adjacent to an air port of the draught fan, of the side wall of the shell and an air outlet is formed in the position, adjacent to the efficient active carbon filters, of the side wall of the shell. Wheels are installed at the four corners of the bottom face of the shell respectively. The high-voltage electrostatic adsorption technology is adopted in the movable type air purifier for the tent, so that the air purifier is convenient to clean and maintain and suitable for being used in fields.
