Cabin air filter with polarisation

A gas filter having an upstream facing side, a downstream facing side, and a peripheral narrow facing side connecting the upstream facing side and the downstream facing side, the gas filter comprising at least:

• a filter medium configured to filter a gas flow moving from the upstream facing side through the filter medium to the downstream facing side, wherein the filter medium comprises and/or forms a capacitor, and wherein the capacitor has at least a first electrode, a second electrode, and a dielectric medium, wherein the first electrode, the second electrode and/or the dielectric medium is structured as a filter layer,
• at least a non-conducting first support, wherein the capacitor is attached to the non-conducting first support,
• a first electrical contact at a first location,
• a second electrical contact at a second location,
• a branching point, a first resistive component having a first resistance, and a second resistive component having a second resistance,
• wherein:
• each of the first electrical contact and the second electrical contact is attached to the first support and/or is unitary with the first support,
• each of the branching point, the first resistive component, and the second resistive component is attached to the non-conducting first support or is a part of the non-conducting first support,
• the first electrical contact is electrically connected via the first resistive component to the branching point,
• the second electrical contact is electrically connected via the second resistive component to the branching point and the first electrode is electrically connected to the branching point, and
• the second electrode is electrically connected to the second electrical contact.
