[0002] Effectively treat the air quality so that humans can breathe clean air in an effective environment, especially indoors, which can improve the air quality in work areas or living areas; the existing fresh air filter box needs to use activated carbon rods to eliminate odors in special occasions to achieve the purity of the input airflow; the existing structure generally installs an activated carbon rod in the filter box, and an annular gap is left for ventilation between the outer sides of the activated carbon rod and the filter box. The airflow is input into the filter box. When the airflow passes through the annular gap for ventilation, the airflow can contact the activated carbon rod, so that the airflow is purified. However, the space of the annular gap for ventilation is small, which makes the ventilation volume low and the external airflow replacement speed slow. For this reason, the annular gap for ventilation can be increased, but after the annular gap for ventilation is increased, the airflow outside the annular gap cannot fully contact the activated carbon rod, which makes the airflow purification efficiency low.
