PURPOSE:To make a compact air cleaning filter by a method wherein a deodoring agent is added to a filter net of synthetic resin and a complex air filter is made by a non-woven fabric by heat melting an electrical charged fiber and then the filter is disposed in an aeration passage of a main body. CONSTITUTION:A reinforcing filter net 1 and a non-woven fabric 3 formed by heat melting (heat embossing) an electrical charged fiber onto the reinforcing filter net are made into an integral structure so as to form a complex air filter 4 and then the integral structure is stored in a resin frame 5. The complex air filter is removably inserted from a lower part into a spacing between a pre-filter (air filter) 7 placed at a front position of an air conditioner 6 and a heat exchanger 8. Then, interior air flowing under a rotation of a fan 9 passes through the pre-filter 7 at an operator's side and then passes through the complex air filter 4. Dusts are adsorbed to the electrical charged non-woven fabric 3, odor contained in the dusts is deodored with active carbon 2 of the reinforcing filter net 1, and then purified air is cooled or heated by the heat exchanger 8 and an indoor area of a room is cooled or heated. |
