The present disclosure relates to a fine dust removal system including a conductive filter module, and more particularly, to a fine dust removal system having a conductive filter module which includes a cylindrical conductive filter to thereby implement high fine dust removal efficiency with low pressure loss and which can be easily, generally applied to and used in an air cleaner to be installed in windows or in an independent indoor air cleaner.

Methods and apparatus of the present disclosure monitor and change operation of an air filtering system or apparatus dynamically over time. Changes to the air filtering apparatus may be associated with a type of facility and air purity requirements associated with the type of facility. Examples of different types of facilities include an office building, a clean room, and a hospital. Apparatus of the present disclosure may include conventional air filters and may include disinfecting air filter sub-assemblies that use a high voltage to charge particles in the air such that those particles may conglomerate and be captured more easily in an air. Methods consistent with the present disclosure may change an air flow rate or may change the voltage used to charge the air particles as conditions associated with the air of a facility change over time.

The following is an apparatus and a method that enables the automated collection and identification of airborne particulate matter comprising dust, pollen grains, mold spores, bacterial cells, and soot from a gaseous medium comprising the ambient air. Once ambient air is inducted into the apparatus, aerosol particulates are acquired and imaged under a novel lighting environment that is used to highlight diagnostic features of the acquired airborne particulate matter. Identity determinations of acquired airborne particulate matter are made based on captured images. Abundance quantifications can be made using identity classifications. Raw and summary information are communicated across a data network for review or further analysis by a user. Other than routine maintenance or subsequent analyses, the basic operations of the apparatus may use, but do not require the active participation of a human operator.
