AirScore combines real-time and long-term environmental health data to give every address a 0–100 score. A score of 100 indicates excellent air quality with minimal proximal risk and 0 reflects the highest environmental risk.
| Factor | What It Measures | Health Relevance |
|---|---|---|
| Superfund | Distance to EPA-designated hazardous waste cleanup sites | Linked to higher cancer and respiratory risks near long-term exposure |
| Industrial | Proximity to TRI-listed toxic emitters | Increased exposure to carcinogens and particulate pollution |
| Airports | Closeness to major and regional airports | Jet fuel emissions raise ultrafine particles and NOx levels |
| Live AQI | Current airborne pollution index (PM, ozone, etc.) | Triggers respiratory symptoms, especially in vulnerable populations |
| PM2.5 | Long-term exposure to fine particulate matter | Correlated with heart disease, stroke, and premature death |
| Highways | Distance to major highways and road traffic | Traffic-related air pollution worsens asthma and cardiovascular risk |
AirScore™ ranges from 0 to 100, where 100 indicates excellent air quality and 0 reflects the highest environmental risk.
Each factor applies a "penalty" to the perfect score of 100 based on its severity and proximity. For example, PM2.5 is a weighted factor based on its long-term health association with heart and lung disease. Proximity to Superfund sites and industrial plants introduces location-specific risk. Airports are weighted by size—larger airports cause a bigger deduction.
Most people don't know what's in the air around them. Real-time apps show the moment, but AirScore gives a fuller picture. Whether you're buying a home, raising a family, or just curious, your AirScore tells you how clean (or toxic) your everyday environment really is.
