What is the best approach to improving Indoor Air Quality (IAQ)?

Improving Indoor Air Quality (IAQ) is crucial for the health and comfort of building occupants. The best approach often involves addressing pollutants at their source while ensuring sufficient fresh air circulation. Removing or isolating volatile organic compounds (VOCs) directly targets harmful emissions that can adversely affect air quality. These compounds are commonly found in products like paints, cleaners, and adhesives and can contribute to various health issues.

Providing adequate ventilation is equally important as it helps to dilute and disperse indoor pollutants, promoting a healthier environment. This dual tactic, combining source removal and enhanced ventilation, effectively mitigates the risks associated with poor IAQ. By implementing this comprehensive strategy, you not only reduce the concentration of harmful substances in the air but also improve overall indoor air exchange and quality.

While the other strategies might contribute to better IAQ, such as using energy-efficient devices or limiting the use of paints and solvents, they do not specifically focus on both removing harmful emissions and ensuring proper air exchange in the same effective manner that option B does. Air purifiers can help, but they may not eliminate all sources of pollutants and are not a substitute for proper ventilation and source control. Therefore, the most effective method for improving indoor air quality is to remove or isolate VOC-emitting
