Due to the rapid development of the economy, the consumption of coal, oil and other fossil fuels increases year by year, resulting in the problem of air pollution is also increasing. Economic development has also brought about people’s pursuit of quality of life, air pollution on the comfort of life and even human health, will affect. Therefore, not only outdoor air pollution, but also indoor air pollution has gradually received attention [1]. According to the investigation results of the U.S. Environmental Protection Administration, the concentration of indoor air pollutants is at least 2-5 times that of outdoor pollutants, and sometimes can even reach 100 times that of outdoor pollutants [2]. These particles are usually smaller than 10μm in size and can enter the respiratory tract during breathing. Smaller particles can even enter the alveoli and then enter the bloodstream. In addition, these tiny particles are likely to be carriers of bacteria and fungi, and may enrich heavy metals, organic pollutants and acid oxides, which will cause great harm to the human body [3]. All in all, it is of great significance to study indoor air pollution.
