Air filtering device for an air conditioner

An air filtering device for an air conditioner, in particular for filtering particles, preferably pollutants, from air, containing

• a flow path through which air can flow in a flow direction,
• an ionizer, containing numerous discharge electrodes (17), for generating ions in the flow path,
• a grid structure formed from an electrically conductive material, the grid structure being positioned upstream of the ionizer in the flow path in the flow direction, and forms a first electrode,
• a filter positioned downstream of the ionizer in the flow path in the flow direction, the filter has a layer forming a second electrode, comprising an electrically conductive material or formed from an electrically conductive material,
• a high voltage power source containing an electric pole and an electric counter-pole, configured to generate a high voltage, in particular between 5 kV and 15 kV between the pole and counter-pole,
• wherein the pole is electrically connected to the ionizer, and the counter-pole is electrically connected to the first and second electrodes.
