1. A deodorization module provided to a flow channel, the deodorization module comprising:
an upper housing open at a top surface and a lower surface thereof;
a lower housing coupled to the upper housing;
a photocatalytic filter received in the upper housing through the top surface of the upper housing and disposed inside the flow channel in which air flows in a first direction;
a light source unit comprising at least one light source adapted to emit ultraviolet light towards the photocatalytic filter and a substrate on which the at least one light source is mounted; and
a transparent layer disposed between the photocatalytic filter and the light source unit and received in the upper housing through the lower surface of the upper housing, wherein the transparent layer is configured to shield the photocatalytic filter and the light source unit from each other by preventing a fluid communication between the photocatalytic filter and the light source unit;
wherein the photocatalytic filter, the transparent layer, and the light source unit are sequentially disposed along a second direction perpendicular to the first direction, and
wherein the deodorization module is arranged in and adjacent to the flow channel such that at least a part of the photocatalytic filter is disposed inside the flow channel and configured to contact and clean air flowing inside the flow channel and that the light source unit is disposed outside the flow channel and is free from contact with the air flowing inside the flow channel.
