An air filtering apparatus of a liquid electrophotographic printer is mounted on a charger and includes a suction device sucking air in a main body of the printer and a filtering device filtering pollutants contained in the air sucked by the suction device. The suction device includes a discharge wire disposed adjacent to a photoreceptor web, a holder supporting the discharge wire located between the holder and the photoreceptor web and having one side facing the photoreceptor web, an opening formed in the other side of the holder, a cover coupled to the other side of the holder, a hollow portion formed inside of the cover, a slot formed on the cover and connecting the hollow portion to the opening, and an exhaust hole formed on one end of the hollow portion, and a suction pump connected to the exhaust hole and sucking air through the exhaust hole so that the air near the charger and the photoreceptor web can be exhausted through the opening of the holder, the slot and hollow position of the cover, and the exhaust hole. A plurality of filters are coupled to the suction pump. Pollutants such as ozone and solvent and carbon materials contained in the air are removed while the air is filtered by the filters and than exhausted outside of the main body of the printer.
