ABSTRACT:
An improved electrostatic air purifier and ionizer combining the functions of filtration, precipitation and generation of negative ions. An intake fan draws ambient air within a room into the device through a mechanical filter. The filtered air then passes through an electrostatic field created between an upstream positively charged silver or silver-alloy electrode, preferably in the form of a wire screen or mesh, and a downstream negatively charged gold or gold alloy electrode, preferably in the form of a number of thin strands of wire strung across the air flow path. The interelectrode voltage and fan speed are individually adjustable to optimize the ionizer output to the environment in which it operates.
