Abstract
A method for filtering air includes: passing air through a prefilter disposed in a housing to remove at least a portion of particulates suspended in the air to thereby create prefiltered air; passing the prefiltered air by an ionizer disposed in the housing to ionize at least a portion of the particulates suspended in the air to thereby create ionized particulates in the prefiltered air, the ionizer downstream from the prefilter and upstream from the fan positioned to create an airflow within the housing; and prior to the prefiltered air exiting the housing with ionized particulates, causing the ionized particulates to pass through an electrostatically charged main filter disposed within the housing downstream from each of the ionizer and the fan.
