AQI is a quick signal, not a full diagnosis
The Air Quality Index, or AQI, turns several pollutants into a simple scale from good to hazardous. It is useful because it tells you how outdoor air may affect daily life, especially for children, older adults, pregnant people, and anyone with asthma or heart disease.
How to read the AQI ranges
- 0-50: Good. Air pollution poses little or no risk for most people.
- 51-100: Moderate. Usually acceptable, but unusually sensitive people may notice effects.
- 101-150: Unhealthy for sensitive groups. Outdoor activity may need planning.
- 151+: Unhealthy. This is a stronger signal to understand local pollution patterns.
Look beyond today's number
A single clean day does not tell you the whole story. When relocating, look for seasonal patterns: wildfire smoke, summer ozone, winter inversions, nearby highways, industrial corridors, or ports. A neighborhood can feel very different in August than it does during a spring visit.
Questions to ask before choosing an area
- Are bad air days seasonal or year-round?
- Is the home near a major highway, freight route, port, or industrial facility?
- Does wildfire smoke regularly affect the region?
- Will anyone in the home be more sensitive to ozone or particle pollution?
- Are schools, parks, and commute routes exposed to the same air quality patterns?
Bottom line
A good air quality score is not just a low AQI today. For movers, the better question is whether poor air is rare, seasonal, or part of everyday life in the neighborhood you are considering.
