WIPO Patent Application WO/2022/014110

A1

The purpose of the present invention is to improve the efficiency of collection of particularly fine particles without an increase in pressure loss, and to deodorize or sterilize air in a space. This air purification device comprises: a flow passage through which air circulates; an electric dust collection unit (10) that is disposed in the flow passage and that includes a discharge electrode having a body unit and a corona discharge unit for corona discharge which protrudes from the body unit, and a dust collection electrode disposed opposing the discharge electrode; an ozone removal unit (14) that is disposed in the flow passage, and that is capable of removing ozone included in the circulating air; and a control unit (11) that switches between a first mode in which air from which ozone has been removed is supplied from a downstream section of the flow passage to the outside, and a second mode in which air including ozone is supplied from the downstream section of the flow passage to the outside.
