Indoor air quality (IAQ) refers to the quality of the air inside a building or structure. The air quality can be affected by various factors, such as the presence of pollutants, humidity levels, and ventilation. Poor indoor air quality can lead to health problems such as asthma, allergies, and respiratory infections.
In residential settings, poor indoor air quality can be caused by a variety of factors, including poor ventilation, cooking, smoking, and pet dander. Commercial spaces such as hospitals, offices, and schools also face similar challenges.
