(B) Prior art As a prior art of an air purifier having an air purifying filter to which a voltage is applied, there is one proposed by the applicant in Japanese Patent Application No. 1-140304. The air purifier includes a support frame having a positive terminal and a negative terminal for applying a voltage, and a terminal that contacts a terminal of the support frame, and an air cleaning filter detachably attached to the support frame. Is provided in a ventilation path, and is configured to charge and remove dust in the ventilation path.

(C) Problems to be Solved by the Invention In the air purifier described above, the terminals of the air purifying filter are attached to the frame of the air purifying filter so as to be flush with the frame, and the frame is connected to the supporting frame. An air purification filter was attached to the support frame so as to be almost in contact. For this reason, dust adheres to the support frame and the air purifying filter due to long-term use, and if the dust contains moisture, the positive terminal and the negative terminal are easily conducted through the dust, and may be short-circuited.
