| 摘要 |
The present invention relates to an air purifying apparatus for air ventilation, comprising: a cylindrical filter unit which has a hollow air passage formed in the center thereof; a damper unit which is disposed in a lower part of the filter unit, and selectively opens and closes the inflow of external air; a blower unit which is disposed to communicate with the air passage of the filter unit, and provides air purified by the filter unit; and a housing which accommodates the filter unit, the damper unit, and the blower unit. According to the present invention, a HEPA filter and a HEGA filter which are installed in the air purifying apparatus can be integrally assembled to be separated from each other, such that only the exhausted filter can be replaced without integrally replacing the filters having different life cycles, thereby reducing costs for maintenance of the air purifying apparatus. In addition, the air purifying apparatus can be installed either outdoors or indoors regardless of location, and can freely control a blowing direction of the purified air in accordance with the installation location, since the damper unit can be selectively operated and blowing direction of the purified air can be selectively controlled. |
