Abstract: A photocatalyst for air purification, a photocatalyst film including the photocatalyst, and an air purification device including the photocatalyst. The photocatalyst for air purification includes: a first metal oxide particle having ultraviolet absorptivity, and fluorine bound to a surface of the first metal oxide particle; second metal oxide particles present on the surface of the first metal oxide particle. The use of the photocatalyst for air purification to remove or degrade volatile organic compounds (VOCs) and viruses.

Abstract: Provided are an air purification module and an air purification system including the same. The air purification module is configured to purify influent unpurified air and discharge purified air and includes: a catalyst filter including a photocatalyst and an oxidation catalyst; and a light-emitting heat source disposed adjacent to the catalyst filter, wherein the light-emitting heat source irradiates, to the catalyst filter, light for activating the photocatalyst, and provides heat to activate the oxidation catalyst, and a temperature of the light-emitting heat source is higher than a temperature of the unpurified air.

Abstract: A filter and a filter system including the filter. The filter includes a porous filter frame having a first upstream-side surface, and a second downstream-side surface based on a thickness direction, the porous filter frame filtering particulate matter. A copper material layer is disposed on at least a portion of the first upstream-side surface of the filter frame.
