(57) [Summary] [PROBLEMS] In the adsorption method of a conventional air purification device, Due to physical adsorption, it may have a relatively short life and release odors attached, leading to secondary pollution. The photocatalyst method has a slow operation due to the amount of ultraviolet light and the contact time with the catalyst, etc., and has a problem in air purification efficiency with a small machine. In the plasma method, excess ozone and acid gas generated during the operation are generated by the human body. Harmful to. SOLUTION: The present invention provides an air ventilation purification device in which outdoor air is purified by passing through a metal oxide filter 5 and a zeolite / photocatalytic filter 6 by a fan 8, and then introduced into the room. And a metal oxide filter 5 In addition, the outdoor air purified by passing through the zeolite / photocatalytic filter 6 is introduced into the room, and the indoor contaminated air is removed to the outside, so that the room air can be purified more quickly. |
