　　Winter is hot and beautiful, but it also increases indoor air pollution. Because most people prefer to stay indoors in the cold and freezing season, the indoor ventilation is reduced in winter, and the degree of indoor environmental pollution is more serious than other seasons. Therefore, our air purifier manufacturers hereby remind you that indoor environmental pollution in winter is more serious, and be alert to the harm of indoor environmental pollution in winter.

　　So what are the reasons for the increase in indoor pollution?

　　1. People spend more time indoors.

　　Due to the low temperature in winter, most people, especially the elderly, children and the infirm, spend more time indoors and spend less time outdoors, resulting in a higher degree of harm to the human body from indoor pollutants than in summer.

　　2. Increased pollutants in indoor air.

　　In addition to pollutants such as formaldehyde, benzene series, TVOC and other harmful gases produced by decoration and furniture accessories, as well as due to combustion and heating, indoor CO, CO₂ and inhalable particulate matter are higher than in other seasons.

　　3. There are fewer opportunities for indoor ventilation.

　　Due to the emphasis on indoor heat preservation, indoor ventilation is reduced, resulting in a large accumulation of indoor pollutants. According to surveys, in the case of poor ventilation, the degree of indoor air pollution in winter is dozens of times more serious than outdoor.

　　4. The number of respiratory diseases and infectious diseases increased.

　　Winter is a season of frequent occurrence of various respiratory diseases and infectious diseases. Because people exercise less, their immunity is relatively low, and pollutants such as formaldehyde, benzene, and ammonia in the air mainly stimulate the human respiratory system and mucous membranes, making the human body resistant. decline, the greater the harm to human health.
