A drying apparatus of an air filter is provided to prevent spray nozzles of a cleaning water distributing pipe from being frozen by cleaning water, by ejecting air of high pressure into the cleaning water distributing pipe. An air supply pipe(100) is disposed between a cleaning water distributing pipe(10) and a compressed air distributing pipe(20). The air supply pipe ejects air of high pressure, which is formed from the compressed air distributing pipe, to the cleaning water distributing pipe for a predetermined time. A solenoid valve(110) is installed on the air supply pipe to prevent nozzles(11) of the cleaning water distributing pipe from being frozen. A timer(200) sets a time of supplying high pressure air which is ejected from the compressed air distributing pipe to the cleaning water distributing pipe by the air supply pipe.
