Indoor air pollution refers to the presence of harmful chemical gases, biological contaminants, and fine particulate matter suspended in the air inside residential homes, offices, schools, and enclosed commercial buildings. Unlike outdoor smog, indoor pollution originates from everyday sources within the living space, including volatile organic compounds emitted by paints, furniture, and cleaning products, combustion gases from unvented heaters, and tobacco smoke. Biological allergens like mold spores, bacteria, pet dander, and dust mites also contribute significantly to indoor pollution. Because modern buildings are tightly sealed for energy efficiency, these invisible toxins can become heavily concentrated, posing serious long-term health risks to the occupants who breathe them daily.
