What is air quality?
Air quality is a measurement system called AQI (air quality index) developed by the Environmental Protection Agency (EPA) to assign a numerical value to the air quality.
This system takes four major air pollutants into account, ground-level ozone, particle pollution, carbon monoxide, and sulfur dioxide. The higher the AQI, the greater the level of air pollution.

Understand the scale
The higher the Air Quality Index (AQI) value, the greater the level of air pollution and the greater the health concern. The AQI is divided into six (6) categories as listed below. Each category corresponds to a different level of health concern.
The State of Colorado's Air Quality page provides the AQI for here in the Grand Valley.
AQI color key

- Yellow – moderate
- Orange – unhealthy for sensitive groups
- Red – unhealthy

PurpleAir ratings
The Air Quality Index above is useful but only monitors several County-wide sensors.
The PurpleAir map of the County showcases where local volunteers place air sensors on their businesses or homes and provides a second data point for local air quality.
