Abstract
A portable personal air ionizer includes a dielectric housing small and lightweight enough to be hand carried. The housing contains a circuit for deriving a negative voltage having sufficient value to ionize air molecules, electrodes having pointed ends connected to the high voltage and a ground plane electrode. The negative ions collect airborne particulates which fall by gravity to a collecting pad beneath a stand for fully supporting the housing. Three electrodes are on each of two sheet metal strips, each having an elongated base mounted on a dielectric board. Each electrode is formed as a triangle extending upwardly from the base. The housing includes a central region having an interior wall spaced from an exterior wall. The interior wall forms a well where the circuit is located, surrounded and held in place by a potting compound. An edge of the dielectric board abuts against a dielectric wall between the ground plane electrode and the pointed electrodes. The board is tilted upwardly with respect to the ground plane electrode, with the pointed electrodes extending generally at right angles to the board. The electrodes are dimensioned and positioned relative to each other to clear smoke from an enclosed one cubic foot volume in less than approximately one minute, even though the ionizer does not include a fan.
