Electrostatic Air Filter
First Claim
1. A filter for separating very small particles or organisms from the air or gas in which they are carried, comprising a filter mechanism and a duct, chamber or pipe to contain and transport the air or gas and to house the filter mechanism;
- the filter mechanism comprising;
a particle charging means,a means to introduce charged or uncharged atomized droplets of liquids or reagents into the air or gas after the particle charging stage, anda capture means for collecting the atomized droplets and/or very small particles or organisms;
the capture means comprising one or more of;
a) a maze of fine wire or filament conductors held at a high voltage and through which the air or gas is passed,b) a plurality of vertically orientated filaments held at high voltage and through which the air or gas is passed, orc) one or more vertically orientated collector plates held at high voltage.
