Abstract
The invention relates to an electrostatic particle filter for removing particles from air. The electrostatic particle filter includes a filter medium () with first and second opposite sides, a first electrode () and a second electrode (), the first electrode () and second electrode () being conformally provided on the first and second sides of the filter medium (), respectively. The first electrode (), the second electrode (), and the filter medium () are arranged to allow an electrical conduction current through the filter medium (). The first electrode () is a moderately-conductive electrode having a sheet resistance in a range with a lower boundary value of about 10Ohm per square and an upper boundary value of about 10Ohm per square, at a relative humidity of 30%. The invention also relates to an electrostatic filtration system including the electrostatic particle filter, and a particle charging section ().
