1. A self-contained ion emitting brush, comprising:

  • a handholdable body defining at least one vent and having a region to which a grooming attachment may be affixed;

    a self-contained ion generator disposed in said body and including;

    a high voltage generator having first and second output ports, one of which ports may be at a same potential as ambient air, that outputs a signal whose duty cycle can be about 10% to about 100%; and

    an electrode assembly, effectively coupled between said output ports, comprising a first electrode array that includes at least one electrode having a pointed tip aimed generally in a downstream direction, and a second electrode array that includes at least one electrically conductive member through which there is defined at least one substantially circular opening disposed generally coaxial with and in a downstream direction from said pointed tip of said first electrode, said electrically conductive member having a first surface facing said first electrode array and, transitioning smoothly and continuously from said first surface, a second surface surrounding a periphery of said substantially circular opening to form a skirt-like region having a single continuous interior surface, said skirt-like region extending in said downstream direction;

    wherein said ion generator outputs an electrostatic flow in a downstream direction toward said second electrode array, said electrostatic flow including at least one of ionized air and ozone.
