Pursuing enhanced air purification strategies becomes particularly justifiable in scenarios where external air quality is likely to be compromised due to pollution sources. A building situated near heavily trafficked roads and manufacturing plants is exposed to higher levels of particulate matter, volatile organic compounds (VOCs), nitrogen dioxide, and other pollutants. These contaminants can significantly impact indoor air quality (IAQ) if not effectively filtered out. Enhanced air purification methods, such as advanced HVAC systems with high-efficiency particulate air (HEPA) filters, activated carbon filters, or other technologies, can mitigate these external pollution influences, ensuring healthier indoor environments for occupants. This approach aligns with WELL's focus on maintaining optimal indoor air quality to support occupant health and well-being.
