It is understood that the World Health Organization has listed indoor air pollution as the first among 18 types of carcinogens. The Lanzhou Indoor Pollutant Detection and Control Center also stated that home decoration, smoking, dust under the bed and bedding, and air conditioners are all major sources of indoor pollution.
According to a set of data from the World Health Organization, 24 million deaths worldwide every year are closely related to indoor PM2.5, and 110,000 people die in my country every year. In addition to pollution caused by excessive decoration and improper decoration, there is also pollution from other sources. Certain compounds excreted through breathing and sweat in the office, viruses expelled by coughing and sneezing, and pollutants such as smoke produced by smoking are all very harmful to human health.
