摘要： An air cleaning apparatus capable of predicting a breakthrough time of a filtering portion is provided. Regarding a mask 1 as one example of the air cleaning apparatus, data on concentration of the poisonous gas element with which in ambient air (40) is contaminated on the upstream side of a filtering portion (3), a flow rate of the air (40) passing through the filtering portion (3), a temperature of the air (40), and relative humidity of the air (40) are input to an arithmetic processing unit (25). 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 (25), and the breakthrough time of the filtering portion (3) is calculated through the prediction formula, based on the data on the concentration and the like.

摘要： Provided is a protective mask that is highly comfortable to wear. A protective mask (1) includes: a face piece (11); an eyepiece (15) attached to the face piece; and a lip (13) extending from an outer circumference (12) of the face piece in a direction crossing the face piece, in which at least a part of the lip includes a face contact portion (14) capable of coming into contact with a face of a wearer, the face contact portion is formed from a silicone rubber, the face piece and the lip are formed from a gas impermeable material except for the face contact portion, and the gas impermeable material and the silicone rubber are joined together along the boundary between the gas impermeable material and the silicone rubber.
