a body provided in the circulation passage; and

an opening provided to pass through the body, wherein the filter is fixed to the opening, and wherein the filter washer is provided at and fixed to the body, and includes:

a passage body provided above the opening and into which washing water is received;

one or more discharge hole that discharges the washing water inside of the passage body to the filter; and

a connection body exposed to an outside of the circulation passage by passing through the circulation passage and connected to a water source so as to supply the washing water to the passage body.

2. The laundry treating apparatus of claim 1 , wherein the one or more discharge hole sprays washing water such that foreign materials remaining on the filter are moved toward the inlet.

3. The laundry treating apparatus of claim 1 , wherein the filter frame is removably provided in the circulation passage.

4. The laundry treating apparatus of claim 1 , wherein a distance from a lower end of the filter to the inlet is shorter than a distance from an upper end of the filter to the inlet.

5. The laundry treating apparatus of claim 1 , wherein a distance from a lower end of the filter to the inlet is longer than a distance from an upper end of the filter to the inlet.

6. The laundry treating apparatus of claim 1 , wherein the filter is formed to have a convex surface in a direction that extends away from the inlet.

7. The laundry treating apparatus of claim 6 , wherein the inlet is provided on a plane in contact with a lower end of the filter, and wherein the filter frame further includes a guider that guides air introduced from the inlet toward the filter.

8. The laundry treating apparatus of claim 1 , further including a heat exchanger washer configured to spray washing water onto the heat exchanger.

9. The laundry treating apparatus of claim 8 , wherein the heat exchanger washer includes:

a passage body provided in a widthwise direction of the circulation passage, that receives washing water thereinto; and

one or more discharge hole that discharges the washing water inside of the passage body to the heat exchanger.

10. The laundry treating apparatus of claim 1 , wherein the heat exchanger includes:

at least one first heat exchange plate that exchanges heat with air inside of the circulation passage;

at least one first refrigerant pipe fixed to the at least one first heat exchange plate;

at least one second heat exchange plate provided in the circulation passage, that exchanges heat with air which has passed through the at least one first heat exchange plate;

at least one second refrigerant pipe fixed to the at least one first heat exchange plate and to the at least one second heat exchange plate;

a compressor that supplies a refrigerant discharged from the at least one first refrigerant pipe to the at least one second refrigerant pipe, in a compressed manner; and

an expansion device that moves the refrigerant discharged from the at least one second refrigerant pipe, to the at least one first refrigerant pipe, after lowering a pressure of the refrigerant.

11. The laundry treating apparatus of claim 10 , wherein the circulation passage includes:

a first mounting device that supports the heat exchanger; and

a second mounting device that supports a lower end of the filter frame, wherein the second mounting device is provided at a higher position than a position of the first mounting device.

12. The laundry treating apparatus of claim 11 , wherein the circulation passage further includes:

a drain device that discharges the water inside of the laundry accommodation device; and

a discharge pipe that connects the first mounting device with the drain device.

13. A laundry treating apparatus, comprising:

a laundry accommodation device that provides a space in which laundry is accommodated, the laundry accommodation device having an exhaust device that exhausts air and a supply device that supplies air;

a circulation passage that guides air exhausted from the exhaust device to the supply device, the circulation passage having an inlet that accommodates the exhaust device;

a heat exchanger provided in the circulation passage;

a filter frame removably provided adjacent to the inlet;

a filter fixed to the filter frame and provided in the circulation passage; and

a filter washer fixed to the filter frame, that supplies washing water to the filter, wherein the filter frame includes:

a body provided in the circulation passage; and

an opening provided to pass through the body, wherein the filter is fixed to the opening, and wherein the filter washer is provided at and fixed to the body and includes:

a passage body provided above the opening and into which washing water is received;

one or more discharge hole that discharges the washing water inside of the passage body to the filter; and

a connection body exposed to an outside of the circulation passage by passing through the circulation passage and connected to a water source so as to supply the washing water to the passage body.

14. The laundry treating apparatus of claim 13 , wherein the filter is formed to have a convex surface in a direction that extends away from the inlet, wherein the inlet is provided on a plane in contact with a lower end of the filter, and wherein the filter frame further includes a guider that guides air introduced from the inlet toward the filter.

15. A laundry treating apparatus, comprising:

a laundry accommodation device that provides a space in which laundry is accommodated, the laundry accommodation device having an exhaust device that exhausts air and a supply device that supplies air;

a circulation passage that guides air exhausted from the exhaust device to the supply device, the circulation passage having an inlet that accommodates the exhaust device;

a heat exchanger provided in the circulation passage;

a filter frame provided adjacent to the inlet;

a filter fixed to the filter frame and provided in the circulation passage, wherein the filter is formed to have a convex surface in a direction that extends away from the inlet; and

a filter washer fixed to the filter frame, that supplies washing water to the filter, wherein the filter frame includes:

a body provided in the circulation passage; and

an opening provided to pass through the body, wherein the filter is fixed to the opening, and wherein the filter washer is provided at and fixed to the body and includes:

a passage body provided above the opening and into which washing water in received;

one or more discharge hole that discharges the washing water inside of the passage body to the filter; and
