Abstract
A bipolar charger includes a housing with a main chamber and positive and negative electrode chambers facing each other. The electrode chambers each have a ground electrode and a high voltage electrode that cooperate to create a cloud of ions. An aerosol flowing from an inlet passage through the main chamber and out an outlet passage mixes with the clouds of ions, thereby providing an aerosol with a steady-state electric charge distribution.
