Interpreting Your Air Quality Data and Taking Action
Your air quality sensor’s data becomes actionable only when you understand the Air Quality Index (AQI) scale, which the EPA defines across six categories from Good (0-50) to Hazardous (301-500).
Indoor pollutants typically originate from combustion sources, building materials, cleaning products, and outdoor infiltration—each requiring specific mitigation strategies based on your sensor’s particulate matter (PM2.5/PM10) and volatile organic compound (VOC) readings.
Once you’ve identified heightened pollutant levels, you’ll need to implement targeted interventions including source elimination, ventilation improvements, and filtration upgrades to achieve compliance with recommended exposure limits.
Understanding AQI Score Levels
Air Quality Index (AQI) values translate complex pollutant measurements into a standardized 0-500 scale that allows you to assess health risks at a glance.
Understanding these AQI indicators equips you to implement protective measures before adverse AQI health effects compromise your environment.
The EPA-designated categories are:
- 0-50 (Good): Air quality meets regulatory standards; no restrictions necessary for any population group
- 51-100 (Moderate): Acceptable quality; unusually sensitive individuals should monitor symptoms and limit prolonged outdoor exertion
- 101-150 (Unhealthy for Sensitive Groups): Children, elderly, and individuals with respiratory conditions must reduce extended outdoor activities
- 151-200 (Unhealthy): General population will experience health effects; sensitive groups face serious impacts requiring immediate action
Values exceeding 200 demand emergency protocols.
Your smart sensors provide real-time AQI monitoring, facilitating data-driven decision-making that protects occupants and maintains compliance with health standards.
