Several underlying causes contribute to poor indoor air quality. Common sources include dust, mold, pet dander, tobacco smoke, and volatile organic compounds (VOCs) emitted from household products. Insufficient ventilation can trap these pollutants indoors, leading to a buildup over time. Temperature and humidity levels also significantly influence air quality, as high humidity can encourage mold growth, while low humidity can cause irritation of the respiratory tract.

Volatile organic compounds (VOCs) are chemicals found in many household items like paints, cleaning products, and furniture. When these products evaporate, they release VOCs into the air. Exposure to high levels of VOCs can cause headaches, dizziness, and long-term health effects.

Inadequate ventilation plays a major role in poor indoor air quality. For instance, if windows and doors are kept closed for long periods, harmful substances remain trapped inside. Regular activities, such as cooking and cleaning, can further contribute to the accumulation of pollutants. Additionally, household items like candles or air fresheners may also release harmful particles.

Known actions that contribute to indoor air quality issues include smoking indoors, neglecting to clean regularly, and using chemical-based cleaning products. For example, smoking in a living room fills the air with harmful chemicals that linger long after the cigarette is extinguished. Another scenario is when homeowners regularly use aerosol sprays without adequate ventilation, leading to the buildup of harmful particles in the air.
