What do the air quality indicator icons mean?

What are the different air quality levels?

AQI: 0-50

Good: Air quality is considered satisfactory, and air pollution poses little or no risk.

AQI: 51-10

Moderate: Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.


Active children and adults, and people with respiratory disease, such as asthma, should consider limiting prolonged outdoor exertion.

AQI: 101-150

Unhealthy for Sensitive Groups: Members of sensitive groups may experience health effects. The general public is not likely to be affected.


Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.

AQI: 151-200

Unhealthy: Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.


Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion

AQI: 201-300

Very Unhealthy: Health warnings of emergency conditions. The entire population is more likely to be affected.


Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.

AQI: 300+

Hazardous: Health alert: everyone may experience more serious health effects.


Everyone should avoid outdoor exertion.

Air quality is one of the most impactful external factors that may be affecting your health.

Here at Puraka, we use the Air Quality Index (AQI), to measure the level of pollutants present in the air. The AQI is a national system utilized to calculate and report air quality levels, using standards set by the United States Environmental Protection Agency (EPA).

The AQI describes the five main types of air pollution regulated by the Clean Air Act: sulfur dioxide, nitrogen dioxide, carbon monoxide, ground-level ozone, and particle pollution. The EPA and its partners take regular readings of these pollutants and converts the results into a number ranging from 0 to 500, along with a specific color corresponding to a level of health concern. 
Of the pollutants that impact the AQI, PM2.5 (particulate pollution), and ground-level ozone are considered the most dangerous to your health. Wildfires in Oregon, Washington, and Northern and Southern California have been significant contributors to PM2.5 pollution.

Particulate pollution refers to small particles in the air such as dust, smoke, dirt and soot. These types of particles are small enough that they can be absorbed directly into your bloodstream via the lining in the lungs, and can be the cause of labored breathing, inflammation and increase the risk of heart and asthma attacks. Ground-level ozone is generated when polluted air comes in contact with sunlight and heat. It's most common in the summer, in the afternoon and early evening.
