1. An air purifying apparatus comprising:
- a. an inlet into which a flow of input air is directed, said input air containing a plurality of particulates;
b. an outlet out of which a flow of output air is directed;
c. at least one emitter through which a fluid is sprayed into a plurality of electrically charged droplets, said droplets comprising a first electrical potential, wherein said droplets intermix with said input air and transfer charge to a portion of said plurality of particulates forming a plurality of charged agglomerates in a first zone;
d. a conductive surface comprising a second electrical potential, wherein a portion of said plurality of charged agglomerates are collected on said conductive surface and removed from said input air;
e. a deflecting element comprising a third electrical potential and disposed in a second zone, said second zone in air flow communication with and downstream from said first zone; and
f. a collective surface comprising a fourth electrical potential and disposed in said second zone, wherein said deflecting element deflects a final portion of said plurality of charged agglomerates onto said collective surface, resulting in reduced particulates in said output air.

Abstract
A dynamic electrostatic apparatus for purifying air is provided. In some embodiments, the apparatus includes at least one emitter through which a fluid is sprayed into a plurality of electrically charged droplets that intermix with particulates in incoming air and form a plurality of charged agglomerates. A minor portion of such charged agglomerates are collected on a conductive surface and removed from the input air, while a major portion of such charged agglomerates are deflected by a deflecting element onto a collective surface. Thus, the apparatus reduces particulates in output air. In some embodiments, the emitter includes an array of hydrophilic spray fibers.
