Abstract: An ion filtration air cleaning device for cleaning air by use of electrostatic ion attraction. Air having suspended particles is drawn into the device through an inlet by a fan. An ionization source near the inlet generates ions. Electrical charge transfers from the ions to the suspended particles. The fan pushes the air and suspended charged particles toward an outlet.

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.

Abstract: An ion filtration air cleaning device for cleaning air by use of electrostatic ion attraction. Air having suspended particles is drawn into the device through an inlet by a fan. An ionization source near the inlet generates ions. Electrical charge transfers from the ions to the suspended particles. The fan pushes the air and suspended charged particles toward an outlet. A filter located adjacent to the outlet operates by electrostatic attraction and filters the charged particles from the air, allowing cleansed air to be released from the device, with a reduced level of charged particle emission.
