If the doors and windows are closed, people will release exhaust gas and carbon dioxide while living indoors, which will reduce the indoor air quality. In the long run, it will be harmful to human health. If the indoor air is not circulated, a large number of bacteria, viruses and other microorganisms that may cause disease will breed. Indoor ventilation can effectively use sunlight and ultraviolet rays in the air to kill germs, remove harmful gases in the indoor air, and purify the air. Traditional ventilation devices do not have air filtering functions and air odor adsorption functions. During use, they cannot effectively filter impurities in the air and remove odors in the air, and therefore cannot improve the indoor air quality.
