Abstract: A space purification device according to the present disclosure includes: electrolysis bath; water supply unit; electrode unit (140); first calculator (510) that calculates an increased concentration of hypochlorous acid water per unit time based on (i) a first sodium chloride concentration that is a sodium chloride concentration in the electrolysis bath after the sodium chloride concentration has changed due to an input of the electrolysis accelerator into the electrolysis bath and (ii) hypochlorous acid generation efficiency per unit time set in advance; second calculator (512) that calculates, based on a target hypochlorous acid water concentration in the electrolysis bath, a first hypochlorous acid water concentration that is a hypochlorous acid water concentration in the electrolysis bath before energization by electrode unit (140), and the increased concentration of hypochlorous acid water per unit time calculated by first calculator (510), a required energization time for achieving the target hypochlorous acid water concentration; and electrode controller (540) that performs energization in electrode unit (140) for the required energization time calculated by second calculator (512).
