Indoor pollution is considered an indoor exposure of harmful pollutants within enclosed spaces, such as homes, workplaces, and schools, that affects health. Among the most common indoor pollutants are VOCs, mold, dust mites, carbon monoxide, radon, and particulate matter from tobacco smoke and cooking. Most of the time is spent indoors, and one might be exposed to such pollutants without adequate ventilation, making poor indoor air quality a significant public health problem.

Health effects of indoor pollution range from minor irritation of the respiratory system to serious disorders like asthma and allergy, and even cardiovascular disease. Furthermore, long-term exposures of children to indoor pollutants are critical causes of early childhood diseases and pre-existing risks in children, elderly, or people with other diseases. For example, house cleaning agents, paints, and furnishings often emit VOCs that may cause headaches, nausea, and irritation to the eye and throat, while prolonged exposure has been connected to more harmful problems related to the respiratory and immune systems.

If effective, among the most effective ways to reduce indoor pollution is through improving ventilation. Adequate ventilation dilutes pollutants while bringing in fresh air and reduces harmful particles from concentration within the indoors. Public health guidelines recommend that one should utilize exhaust fans or windows, if feasible, along with an air purifier for improving the quality of the air within a space with poor airflow.

Controlling sources of indoor pollution is also important. Natural or low-VOC household products, no smoking indoors, and frequent cleaning reduce the levels of dust and pet dander significantly. Devices to monitor carbon monoxide and radon contribute to safer indoor environments by alerting occupants to high levels of these hazardous gases.

Public health initiatives in the promotion of good indoor air quality include educating the communities on various sources of indoor pollution and awareness raising and healthy building standard promotion. By reducing health risks through indoor pollution, communities can achieve greater safety and comfort in indoors.
