Electrostatic air filter device

An electrostatic air filter assembly comprising:

• a first rectangular frame having a top, bottom and two side edges;
• a first wire mesh disposed within said first frame;
• a second rectangular frame having a top, bottom and two side edges;
• a second wire mesh disposed within said second frame, said second frame being joined at one side edge to one side edge of said first frame by a hinge means;
• removable first and second rectangular polyester/wool dielectrics disposed between said first and second frames;
• a removable rectangular charging screen disposed between said first and second polyester/wool dielectrics for distributing charge to said first and second dielectrics;
• a high voltage power supply, having an input terminal and an output terminal and a high voltage wire electrically connected to said output terminal, said high voltage power supply being disposed on an edge of said first rectangular frame such that said wire physically and electrically contacts said charging screen when said first and second rectangular frames are closed to form said assembly;
• said high voltage power supply having
• a direct current power supply stage having an input and an output, wherein said input is connected to an output of an alternating current adapter;
• an oscillator stage having an input and an output, said input being connected to said output of said direct current power supply;
• a step-up transformer having a primary and a secondary winding, said primary winding forming said output of said oscillator stage;
• a voltage multiplier stage having an input and an output, said input of said multiplier being connected to said secondary winding, wherein said output of said multiplier forms an output of said high voltage power supply;
• a high resistance, low current leakage resistor connected between said output terminal and ground for quickly discharging said charging screen when the high voltage supply is de-energized.
