Abstract
The present invention relates to a filter core for deodorizing agent filling and a deodorizing filter employing the same. More particularly, the present invention relates to a filter core for deodorizing agent filling and a deodorizing filter employing the same, in which an airflow path to be formed in multiple directions thus enhancing the airflow performance and improving the deodorizing efficiency. Accordingly, airflow can be generated in various directions so that airflow can efficiently flow and the pressure loss due to airflow can be reduced, thereby improving the deodorizing performance. In addition, the path through which the odor components are removed while air passes through the deodorizing agent is increased, thereby increasing a time that air is in contact with the deodorizing agent and improving the deodorizing efficiency.
