CO Daily Verification
AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Satisfactory (51 - 100)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (101 - 200)
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.
AQI: Poor for Sensitive Groups (201 - 300)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Very Poor (301 - 400)
Health alert: everyone may experience more serious health effects.
AQI: Severe (401 - 500)
Health warnings of emergency conditions. The entire population is more likely to be affected.
