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.

An air purifier that purifies air by using a photocatalytic filter carrying a photocatalyst, the air purifier comprising:
- a housing that includes an intake port and an exhaust port;
- a filter unit that includes the photocatalytic filter and that 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 from the intake port through the unit housing toward the exhaust port,
- wherein 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 wherein the filter unit further includes a holding frame, the holding frame has, at both end portions in the first direction of the photocatalytic filter, first frames that keep the wavy shape of the photocatalytic filter, and the first frames includes first openings through which the flow of air passes in the first direction.
