Abstract (en)
A gas filter 1 comprising a filter medium 20, for filtering a gas flow from an upstream facing side 3 through the filter medium 20 to a downstream facing side 4, wherein the filter medium 20 comprises a capacitor with a first electrode 21, a second electrode 22 and a dielectric medium 23, wherein the gas filter 1 further comprises a first electrical contact T1 and a second electrical contact T2. The first electrical contact T1 is electrically connected via a first resistance R1 to a branching point B and the second electrical contact T2 is electrically connected via a second resistance R2 to said branching point B. Further, the first electrode 21 is electrically connected to said branching point B and the second electrode 22 is electrically connected to the second electrical contact T2.
