Indoor CO2 (>1000 ppm)

Indoor CO2 levels above 1000 ppm can affect air quality and health, making it important to monitor these levels in enclosed spaces like offices and schools. Studies have found that high indoor CO2 concentrations are linked with reduced cognitive function and increased risk of airborne infections such as SARS-CoV-2. Additionally, elevated CO2 levels often indicate poor ventilation, which can also lead to higher levels of other pollutants. Connections to air quality metrics like particulate matter levels and overall environmental conditions in schools highlight the importance of maintaining good ventilation systems to manage CO2 concentrations effectively.

While research provides clear associations between high indoor CO2 levels and health impacts, the specific thresholds for adverse effects may vary depending on individual sensitivities and exposure durations.
