<P>PROBLEM TO BE SOLVED: To determine an operation state of an air cleaner in distinction between not only normality and abnormality of an ionizer and a collector but also abnormality, a maintenance period and so forth of a high voltage output device. Ž<P>SOLUTION: Not only a collector voltage detector 100, an ionizer discharge detector 101 and a collector discharge detector 102 but also a current consumption detector 31 for detecting current consumption of the high voltage output device 15, a temperature detector 32 for detecting air temperature in the air cleaner and a fan power consumption detector 33 for detecting power consumption of a fan are provided. Based on detection results of the collector voltage detector 100, the ionizer discharge detector 101, the collector discharge detector 102, the current consumption detector 31, the temperature detector 32 and the fan power consumption detector 33 and according to logic set in advance, an air cleaner operation state determining part 24 synthetically determines the operation state of the air cleaner including abnormality, the maintenance period and so forth of the high voltage output device 15.
