As an invisible guardian of indoor air quality, air filters play a crucial role in improving indoor air quality. Firstly, air filters can significantly reduce the particulate matter content in indoor air, reducing the risk of respiratory diseases caused by inhaling particulate matter. Secondly, air filters can effectively remove microorganisms such as bacteria and viruses from the air, reducing the possibility of disease transmission. In addition, air filters can also remove indoor odors, improve indoor environment, and enhance people's quality of life.

Air filters use specific filtering materials to intercept and adsorb harmful substances such as particles, bacteria, viruses, pollen, dust mites, etc. in the air, thereby achieving the goal of purifying the air. Common filtering materials include fiber filter materials, activated carbon, high-efficiency filter paper, etc. They can capture particles of different sizes and effectively improve indoor air quality.
