When there is insufficient fresh air exchange, indoor pollutants can accumulate to harmful levels, affecting the health of those who spend time in the space. Common Indoor Pollutants Associated with Poor Ventilation Volatile organic compounds (VOCs): These chemicals are emitted from a variety of sources, including building materials, paints, cleaners, furniture, and personal care products. VOCs can irritate respiratory systems, trigger allergies, and even contribute to chronic health problems.
