Abstract
An air purifier includes a housing that includes an intake port and an exhaust port, a filter unit that includes a photocatalytic filter and is housed in a unit housing within the housing, a light source that exposes the photocatalytic filter to light, and a blast fan that generates a flow of air passing through the unit housing. The photocatalytic filter is formed in a wavy shape in which ridge portions and trough portions extending in a first direction are alternately arranged in a second direction orthogonal to the first direction, and the photocatalytic filter is housed in the unit housing such that the flow of air flows along the first direction.
