1. A fluid processing module comprising:
a main body having:
an inlet through which a fluid enters;
a flow channel extending in a first direction therein and allowing the fluid to flow therein; and
an outlet through which the fluid is discharged and connected to the inlet via the flow channel;
an absorption filter disposed substantially perpendicular to the first direction inside the main body;
a photocatalyst filter disposed parallel to the first direction inside the main body; and
a light source unit disposed inside the main body and emitting light towards the photocatalyst filter configured to perform a photocatalytic reaction that generates superoxide anions and hydroxyl radicals,
wherein the flow channel has a first region including an inlet of the flow channel and having a first cross-sectional area, a third region including an outlet of the flow channel, a second region disposed between the first region and the third region and having a second cross-sectional area, wherein the absorption filter is disposed in the first region and the photocatalyst filter is disposed in the second region, the photocatalyst filter exhibiting a predetermined level of deodorization efficiency when the fluid passes through the photocatalyst filter at a predetermined range of flow speeds;
wherein the fluid flows at a first flow speed in the first cross-sectional area and at a second flow speed in the second cross-sectional area; and
wherein the flow channel has a shape that allows the second flow speed to be greater than the first flow speed in response to the fluid entering the flow channel is less than the predetermined range and the first cross-sectional area is greater than the second cross-sectional area; and
wherein the third region has a cross-sectional area that is greater than the second cross-sectional area and increases in the first direction.
