a filter frame having a plurality of through-holes that passes air therethrough; and
a photocatalyst applied to the filter frame to perform a photocatalytic reaction.

2 . The sterilization and deodorization apparatus according to claim 1 , further comprising a light source disposed at one side of the frame to irradiate light onto the filter.

3 . The sterilization and deodorization apparatus according to claim 2 , wherein the light irradiated from the light source has a wavelength of a visible light region.

4 . The sterilization and deodorization apparatus according to claim 1 , wherein the air flows from the plasma device to the filter.

5 . The sterilization and deodorization apparatus according to claim 1 , wherein the plurality of ions includes ozone (O 3 ), and wherein the photocatalyst includes titanium oxide (TiO 2 ).

6 . The sterilization and deodorization apparatus according to claim 1 , further comprising a light source assembly rotatably coupled to the filter frame, that irradiates light onto at least a portion of the filter frame.

7 . The sterilization and deodorization apparatus according to claim 6 , wherein the light source assembly comprises:
a first horizontal portion that covers a portion of a first surface of the filter frame; a second horizontal portion having a same shape as the first horizontal portion, wherein the second horizontal portion covers a portion of a second surface of the filter frame; a vertical portion that connects the first horizontal portion to the second horizontal portion, and a light source that irradiates light onto the filter frame disposed on each of the first and second horizontal portions.

8 . The sterilization and deodorization apparatus according to claim 6 , further comprising a drive motor disposed at one side of the light source assembly to rotate the light source assembly.

9 . The sterilization and deodorization apparatus according to claim 1 , further comprising a light source assembly that covers at least a portion of the filter frame, wherein the at least a portion of the filter frame is covered by the light source assembly.

10 . The sterilization and deodorization apparatus according to claim 9 , wherein the light source assembly comprises:
a first horizontal portion that covers a portion of a first surface of the filter frame; a second horizontal portion having a same shape as the first horizontal portion, wherein the second horizontal portion covers a portion of a second surface of the filter frame; a vertical portion that connects the first horizontal portion to the second horizontal portion; and a light source that irradiates light onto the filter frame disposed on each of the first and second horizontal portions.

11 . The sterilization and deodorization apparatus according to claim 1 , further comprising a light source assembly disposed to be spaced apart from the filter frame to irradiate light onto the filter frame, wherein light source assembly includes:
a light source frame that defines an outer frame of the light source assembly; and a plurality of light sources disposed on the light source frame in a line to irradiate light onto the filter frame.

12 . The sterilization and deodorization apparatus according to claim 1 , wherein the plasma device comprises first and second substrates, which are disposed opposite to each other, and wherein a predetermined space is provided between the first and second substrates.

13 . The sterilization and deodorization apparatus according to claim 12 , wherein the first substrate comprises:
a first substrate body having a plate shape; at least one first flow hole that passes through the first substrate body to guide a flow of air; and at least one pattern frame disposed to surround at least a portion of the first flow hole, and wherein the second substrate comprises:
a second substrate body having a plate shape; and
at least one second flow hole that passes through the second substrate body to guide a flow of the air.

14 . The sterilization and deodorization apparatus according to claim 13 , wherein the at least one pattern frame comprises:
a closed pattern that surrounds the at least one first flow hole; and at least one discharge tip that protrudes from an outer circumferential surface of the closed pattern.

15 . The sterilization and deodorization apparatus according to claim 1 , wherein the photocatalyst is applied to a mesh surface of the filter frame, which is formed by the plurality of through-holes.

16 . The sterilization and deodorization apparatus according to claim 1 , wherein the photocatalyst reduces ozone, which is produced by the plasma device.
