Under Air Quality Monitoring and Feedback, which pollutants and indoor thermal values are monitored?

• A. Particle Count (PM2.5, PM10); Ozone; Carbon Dioxide; Temperature; Humidity
• B. Ozone; Carbon Dioxide; Temperature
• C. Temperature; Humidity; Carbon Dioxide
• D. Particle Count (PM2.5, PM10); Ozone; Carbon Dioxide; Temperature; Humidity

Answer: (D)

The main idea here is that effective Air Quality Monitoring and Feedback looks at both pollutant particles and gases, plus the thermal conditions that affect comfort and IAQ performance. The best answer includes particle counts for PM2.5 and PM10, ozone, carbon dioxide, temperature, and humidity. This combination gives a full picture: PM2.5 and PM10 show the level of particulate matter from dust, smoke, or indoor activities; ozone represents a reactive indoor/outdoor pollutant that can irritate airways; CO2 serves as a proxy for ventilation adequacy and occupancy load; and temperature and humidity provide comfort context and influence pollutant behavior and microbial growth. If any of these items were omitted, you’d lose important feedback: missing particles means you might not detect fine or coarse particulate concerns; missing ozone leaves a gap in detecting a significant indoor pollutant; missing humidity or temperature removes essential comfort and environmental control feedback. Therefore, monitoring all five provides the most complete and actionable picture.
