Indoor environmental quality/indoor air quality (IAQ) is very important to our health and quality of life. The government clarifies the environmental health risks of indoor air quality, and the indoor air pollution rate is several times different from the outdoor air pollution rate. A person has to breathe more than 20,000 times a day. If the air is polluted, it will cause great harm to human health. The main causes of indoor air pollution are ventilation (52%), indoor pollution (17%), outdoor pollution (11%), biomass (10%), and building materials (3%). The sources of indoor pollution include carbon dioxide, pathogenic microorganisms exhaled by the human body, benzene, formaldehyde, and hydrazine produced by interior decoration, as well as dust mites on the air-conditioning filter. About 80% of humans spend their time indoors, and indoor air quality and long-term health are more important.。
