Abstract

An air filter assembly includes an ion source (38) positioned adjacent to the front face of an air filter to inject ions into the arriving air flow. The ions penetrate upstream sufficiently far to have ionized the air and charge particles before their arrival at the filter trapping medium. The ion source (38) is preferably sufficiently thin as to allow the filter with the ion source mounted thereon to be inserted into a filter slot in a duct of an air handling unit.
