An apparatus for cleaning air, and a method for cleaning air using the apparatus, includes a housing including an air inlet through which air to be cleaned flows into the housing and an air outlet through which air that has been cleaned is exhausted from the housing, the housing isolating an interior thereof from external surroundings. A first filtering unit is disposed adjacent to the air inlet and includes a plurality of first filters for removing a first group of contaminants from the air to be cleaned. Each of the plurality of first filters is disposed substantially parallel to each other. A fan for drawing the air to be cleaned into the housing from the external surroundings is disposed in the housing.

What is claimed is: 1. An apparatus for cleaning air, comprising: a housing including an air inlet through which air to be cleaned flows into the housing and an air outlet through which air that has been cleaned is exhausted from the housing, the housing isolating an interior thereof from external surroundings; a first filtering unit disposed adjacent to the air inlet and including a plurality of first filters for removing a first group of contaminants from the air to be cleaned, each of the plurality of first filters being disposed substantially parallel to each other; and a fan for drawing the air to be cleaned into the housing from the external surroundings, the fan being disposed in the housing, wherein each of the plurality of first filters is disposed at an angle less than about 90째 with respect to a direction of air flow. 2. The apparatus as claimed in claim 1, wherein each of the plurality of first filters is disposed in an individual space, so that the air to be cleaned passing through each of the plurality of first filters is independently cleaned by one of the plurality of first filters. 3. The apparatus as claimed in claim 1, wherein the first filtering unit comprises: a plurality of separating walls for defining a plurality of spaces so that only one of the plurality of first filters is disposed in each of the plurality of spaces; and a filter support for supporting a corresponding one of the plurality of first filters, the corresponding one of the plurality of first filters being disposed on the filter support in one of the plurality of spaces at a predetermined angle with respect to a bottom surface of the housing. 4. The apparatus as claimed in claim 1, wherein each of the plurality of first filters is disposed at substantially a right angle with respect to a direction of air flow. 5. The apparatus as claimed in claim 1, wherein the first group of contaminants comprises gaseous or chemical materials. 6. The apparatus as claimed in claim 1, wherein each of the plurality of first filters is a chemical filter. 7. The apparatus as claimed in claim 1, further comprising a second filter for removing a second group of contaminants, the second filter being disposed adjacent to the air outlet. 8. The apparatus as claimed in claim 7, wherein the second filter is a high efficiency particulate air (HEPA) filter or an ultra low pneumatic air (ULPA) filter. 9. The apparatus as claimed in claim 7, wherein the second group of contaminants has a particle shape. 10. The apparatus as claimed in claim 1, further comprising a plurality of casters for facilitating movement of the housing, the plurality of casters being positioned on a bottom surface of the housing. 11. The apparatus as claimed in claim 1, further comprising a control unit for controlling a revolution speed of the fan, the control unit being connected to the fan. 12. The apparatus as claimed in claim 1, further comprising a medium filter positioned within the housing between the air inlet and the first filtering unit. 13. The apparatus as claimed in claim 1, further comprising a flexible duct for drawing the air to be cleaned into the air inlet, the flexible duct being extendable to an area of local contamination to minimize an amount of the air to be cleaned. 14. A method of cleaning air, comprising: receiving air to be cleaned from an area where the air is locally contaminated; removing a first group of contaminants from the received air using a plurality of first filters, each of the plurality of first filters being disposed in a path of air flow of the received air, the plurality of first filters being arranged substantially parallel to each other; and exhausting cleaned air, from which the first group of contaminants has been removed by the plurality of first filters, to external surroundings, wherein each of the plurality of first filters is disposed at an angle less than about 90째 with respect to a direction of air flow. 15. The method as claimed in claim 14, wherein the received air is divided between each of the plurality of first filters, and each of the plurality of first filters independently removes the first group of contaminants from a divided portion of the received air. 16. The method as claimed in claim 14, wherein the first group of contaminants comprises gaseous or chemical materials. 17. The method as claimed in claim 14, further comprising removing a second group of contaminants from the received air using a second filter after removing the first group of contaminants. 18. The method as claimed in claim 14, wherein the second group of contaminants has a particle shape.
