An air sterilizing apparatus includes an enclosed housing which accommodates radiant sterilizing tubes carried by a holder capable of moving out of the housing or retracting thereinto by means of a moving mechanism. When the holder is moved out, the radiant sterilizing tubes thus exposed sterilize the external air surrounding the housing. When the holder is moved back into the housing, the radiant sterilizing tubes sterilize the air drawn into the enclosed housing through an inlet, after which the sterilized air is discharged through an outlet of the housing.
