What is a common source of air pollutants?

Home furnaces are indeed a common source of air pollutants. They can release various harmful emissions, including particulate matter, carbon monoxide, and volatile organic compounds (VOCs), particularly if they are not properly maintained or are outdated models. Depending on the fuel source—whether natural gas, oil, or wood—different types of pollutants can be emitted into the atmosphere, contributing to both indoor and outdoor air quality issues.

While other sources like car emissions and industrial factories are significant contributors to air pollution, home furnaces are particularly relevant as they are used widely in residential areas. Additionally, unlike industrial sources, the emissions from home furnaces can directly affect the air quality within living environments, highlighting their role in overall public health concerns.

Forest fires also contribute to air pollution by releasing large quantities of smoke and particulates into the atmosphere, but they are not considered a continuous source like home furnaces that operate regularly during colder months.
