Abstract
An air cleaner is provided to include a photocatalytic UV LED (57) installed on an UV LED substrate (55), and a photocatalytic filter installed on a surface facing the photocatalytic UV LED while being spaced apart from the UV LED substrate. The photocatalytic filter has a structure in which a photocatalytic material is coated on a base in which a plurality of cells (83) defining an air flow path in a direction toward the photocatalytic UV LED are arranged in parallel adjacent to each other.
