Abstract
An air cleaning apparatus capable of predicting a breakthrough time of a filtering portion is provided. Regarding a maskas one example of the air cleaning apparatus, data on concentration of the poisonous gas element with which in ambient air () is contaminated on the upstream side of a filtering portion (), a flow rate of the air () passing through the filtering portion (), a temperature of the air (), and relative humidity of the air () are input to an arithmetic processing unit (). A breakthrough-time prediction formula in which the concentration, the flow rate, the temperature, and the relative humidity are provided as variables is programmed in the arithmetic processing unit (), and the breakthrough time of the filtering portion () is calculated through the prediction formula, based on the data on the concentration and the like.
