The present invention relates to an eco-friendly anti-microdust fan, which comprises: a motor; a rear protection mesh on which the motor is mounted; a front protection mesh detachably coupled to the front side of the rear protection mesh; and a blowing fan disposed between the front and the rear protection mesh and coupled to a shaft of the motor, wherein: the blowing fan comprises a hub coupled to the shaft of the motor and multiple blades formed on the outer peripheral surface of the hub; the hub has coupling parts formed on the outer peripheral surface thereof and coupled to the blades, respectively; and each of the blades comprises: plates made of an air-permeable material and vertically spaced apart from each other to allow the blade to have a space therein; a fitting part into which the coupling part is inserted; and a screw extending through the fitting part of the blade to be coupled to the coupling part. Therefore, the blade can be made of Korean paper or hemp cloth having fine pores formed thereon, thereby reducing dust in air; can remove odor or bacteria in air by using a filter member made of charcoal or porous metal; and can be separated from the hub and thus can be easily replaced such that a clean state of the blade can be maintained at any time to improve air purifying performance.
