High voltage connection for sparse material

A filter assembly for an active field polarized media air cleaner comprising:

• a conductive screen that conducts a voltage therethrough;
• a probe that delivers voltage to the conductive screen having a first side and a second side, wherein the probe includes a rounded contact point;
• a first conductive, planar patch adhesively attached to the conductive screen first side, wherein the probe is located on the conductive screen first side and delivers the voltage to the conductive screen through contact with the first conductive, planar patch, wherein the first conductive, planar patch is a separate and distinct element from the conductive screen;
• and
• a second conductive patch applied to an opposite side of the conductive screen,
• wherein the second conductive patch is in electrical contact with the first conductive, planar patch;
• wherein the second conductive patch is adhesively connected to the first conductive, planar patch through gaps in the conductive screen.
