Ion filtration air cleaner

1. A method for filtering air, comprising:

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 a fan positioned to create an airflow within the housing;

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, and

mixing the prefiltered air using baffles or a serpentine pathway subsequent to passing by the ionizer and prior to passing through the electrostatically charged main filter.

2. The method of claim 1 , wherein the baffles are separate from the ionizer and the electrostatically charged main filter.

3. The method of claim 2 , wherein the fan is disposed within the housing upstream of the baffles.

4. The method of claim 1 , wherein the serpentine pathway is separate from the ionizer and the electrostatically charged main filter.

5. The method of claim 4 , wherein the fan is disposed within the housing upstream of the serpentine pathway.

6. The method of claim 1 , wherein the electrostatically charged main filter comprises at least one electrically charged collection plate.

7. The method of claim 1 , wherein the ionizer comprises a primary corona discharge emitter and a secondary corona discharge emitter.
