Abstract
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.
