Activated carbon sponge odor removing primary filter is designed with a double-sided covered activated carbon sponge. Compared with the ordinary primary filter, it not only effectively filters fine dust particles, but also removes some odors and VOC. The double-sided mesh structure increases the strength of the filter so that it is not easily damaged in the case of high air volume, which ensures long-term stable operation. This innovative design creates clean air for the indoor environment and meets the higher requirements of users for air quality.
