Claims

[Claims for Utility Model Registration] (1) An air purifier comprising an inlet, an outlet, and an air circulation fan, and an activated carbon filter layer disposed in an air flow path between the inlet and the outlet. A bypass flow path is formed in the air flow path to bypass the activated carbon filter layer, and a sensor for detecting a malodorous substance is attached, and only when the malodorous substance is detected by the sensor, the An air cleaner characterized in that a bypass opening/closing mechanism for closing the bypass flow passage is disposed in the bypass flow passage. (2) In an air purifier comprising an inlet, an outlet, and an air circulation fan, and an activated carbon filter layer disposed in an air flow passage between the inlet and the outlet, the air cleaner is provided with an activated carbon filter layer in the air flow passage. A bypass flow passage that bypasses the activated carbon filter layer is formed, and when the air blowing is stopped or the operation is switched from a weak operation state to a strong operation state, the bypass flow passage is kept open for a certain period of time after the switching. An air cleaner characterized in that a bypass opening/closing mechanism is disposed in the bypass flow passage.
