AIR CLEANER AND METHOD FOR PREDICTING BREAKTHROUGH TIME FOR SAME

摘要

The present invention relates to an air cleaner capable of predicting the breakthrough time of a filtering unit. The air cleaner, for example a mask (1), inputs concentration data of toxic gas components included in air (40) upstream of the filtering unit (3), flux data of the air (40) passing through the filtering unit (3), temperature data of the air (40), and relative humidity data of the air (40) into an execution processing unit (25). The execution processing unit (25) is programmed with a formula for predicting the breakthrough time using the concentration, flux, temperature, and relative humidity as variables, and thus the breakthrough time of the filtering unit (3) is predicted from the prediction formula based on data such as concentration.
