The air quality of residential buildings is jointly affected by indoor pollutants, outdoor pollutants, and people's daily activities. Cooking activities, smoking, interior decoration, etc. can all affect the indoor air quality of residential buildings.

People should pay attention to the quality of indoor air, understand the sources of common pollutants and their impact on human health, and study effective and feasible improvement measures.
