An non-discharging type air purification system is provided to supply fully negative ions to the interior of a room, to lower the consumption power and to reduce the maintenance cost. A filter member(2) adsorbs the impurities in the air introduced through plural air inhalation holes(1). A discharging fan(4) inhales air from the filter member and compulsorily discharges the air to an air discharge hole(3). An inorganic matter body(5) is adjacently installed at the air discharge hole. The filter member is constructed by a net plate having plural fluid holes or a minute net sieve. An adsorption material coated on the electric filter member is ceramic powder or powder made of compound zeolite, carbon.
