Abstract
A small personal appliance is wholly contained within a unitary housing that is fully supported by its contact blades being plugged into a wall outlet. The housing includes needles for ionizing the ambient atmosphere and a carbon foam pad for collecting the ionized air. A drive circuit generates cyclically recurring pulses having a voltage which is high enough to ionize the air and low enough to preclude a formation of ozone.
