What is claimed is: 1. A chemical supply system, comprising: at least two supply pipes for supplying at least two different chemicals; a mixing unit connected to the supply pipes for mixing at least two different chemicals to form a chemical mixture, the mixing unit including: an external housing wherein the at least two different chemicals are combined and filtered, one portion of the external housing being connected to one supply pipe and another portion of the external housing being connected to another supply pipe, and an inlet pipe having a plurality of inlet holes floated within the external housing and coupled to an exhausting unit; the exhausting unit positioned at least partially inside the mixing unit for exhausting the chemical mixture externally; and a filtering unit provided between the mixing unit and the exhausting unit for filtering the chemical mixture to prevent chemical particles having more than a predetermined size from being exhausted from the external housing, wherein the at least two supply pipes and an outlet pipe are installed at a first end of the external housing, a mixing fan is installed at a second end of the external housing, and a diameter of the external housing steadily decreases from the first end to the second end. 2. The chemical supply system as claimed in claim 1, wherein the external housing comprises: at least two coupling ports, each coupling port being connected to a supply pipe; and a guiding port for guiding the exhausting unit from an outlet port of the inlet pipe to the outside of the external housing. 3. The chemical supply system as claimed in claim 2, wherein the coupling ports, guiding port and the outlet port are sealed with a sealant. 4. The chemical supply system as claimed in claim 1, wherein the filtering unit is fitted on an outer surface of the inlet pipe and filters the chemical mixture before the chemical mixture flows into the inlet pipe. 5. The chemical supply system as claimed in claim 4, wherein the filtering unit is one of a reverse osmotic pressure filter, a hollow membrane filter or a carbon filter. 6. The chemical supply system as claimed in claim 1, further comprising at least two chemical reservoirs for reserving the chemicals; at least one supply pipe connecting each chemical reservoir with the external housing; and at least one pump operatively associated with each chemical reservoir for pumping the chemicals reserved in the chemical reservoirs through the supply pipe and into the external housing. 7. The chemical supply system as claimed in claim 6, wherein the pumps are installed in the supply pipes. 8. The chemical supply system as claimed in claim 1, further comprising a mixer for mixing the chemicals. 9. The chemical supply system as claimed in claim 8, wherein the mixer includes a mixing blade assembly and a motor operatively engaged with the mixing blade assembly. 10. The chemical mixing apparatus as claimed in claim 1, wherein the external housing is tapered from a first end to a second end. 11. A chemical supply system, comprising: an external housing into which at least two different chemicals flow, wherein the at least two different chemicals are combined and filtered; an inlet pipe floated in the external housing and having a plurality of inlet holes through which the chemical mixture flows in an inner portion of the external housing; a filter fitted on an outer surface of the inlet pipe and filtering the chemical mixture before the chemical mixture flows into the inlet pipe; and an outlet pipe guiding the chemical mixture in the inlet pipe to the outside of the external housing, wherein a first supply pipe, a second supply pipe and an outlet pipe are installed at a first end of the external housing, a mixing fan is installed at a second end of the external housing, and a diameter of the external housing steadily decreases from the first end to the second end. 12. The chemical supply system as claimed in claim 11, further comprising a mixer for mixing chemicals inflowing into the external housing. 13. The chemical supply system as claimed in claim 12, wherein the mixer includes a mixing blade assembly and a motor operatively engaged with the mixing blade assembly. 14. The chemical supply system as claimed in claim 11, wherein the filter is one of a reverse osmotic pressure filter, a hollow membrane filter or a carbon filter. 15. The chemical mixing apparatus as claimed in claim 11, wherein the external housing is tapered from a first end to a second end. 16. A chemical mixing apparatus, comprising: an external housing, wherein a first chemical and a second chemical are combined and filtered; a first supply pipe for supplying the first chemical to the external housing; a second supply pipe for supplying the second chemical to the external housing; a mixing fan installed in the external housing, the mixing fan mixing the first chemical and the second chemical in the external housing to form a chemical mixture; a motor for driving the mixing fan; an inlet pipe having a plurality of inlet holes, the inlet pipe being floated in the external housing; a filter for filtering the chemical mixture before the mixture flows into the inlet pipe, the filter being fitted on an outer surface of the inlet pipe; and an outlet pipe for guiding the chemical mixture in the inlet pipe to the outside of the external housing, wherein the first supply pipe, the second supply pipe and the outlet pipe are installed at a first end of the external housing, the mixing fan is installed at a second end of the external housing, and a diameter of the external housing steadily decreases from the first end to the second end. 17. The chemical mixing apparatus as claimed in claim 16, wherein the motor is installed outside of the external housing. 18. The chemical mixing apparatus as claimed in claim 16, wherein the filtering unit is one of a reverse osmotic pressure filter, a hollow membrane filter or a carbon filter. 19. The chemical mixing apparatus as claimed in claim 16, wherein the external housing is tapered from a first end to a second end.
