To The present invention relates to a vacuum cleaner comprising an anionic filter, to generate negative ions by using the air flow rate generated in a vacuum cleaner inhibit contamination bacteria growth inside the vacuum cleaner and to seize the odor of the exhaust air, the dust collecting in the vacuum cleaner of the internal member, the filter unit being formed of a material that is breathable to air flow is desired containing the tourmaline into a powder processing system therein; And the anionic filter defining the filter unit outer surface, and that with respect to the air flow anion filter consisting of a frame with a mesh net is formed to prevent deformation the filter unit is installed between the rear and the impeller part of the dust collecting member on the airflow path of the vacuum cleaner is to provide a having a vacuum cleaner, the vacuum cleaner is therefore the anion is activated, emitting a high speed of the air flow generated while operating, can sterilize the bacteria, etc., etc. of the vacuum cleaner the dust filter and the deodorizing the odors on the air flow path vacuo and a cleaner outside suppressing discharge is effective to provide a clean vacuum.
