AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
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: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
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: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)

Forecast Discussion: Monday, December 5: Light winds will reduce pollutant dispersion in the Columbus area. However, low pollutant carryover from Sunday will yield Good AQI levels. Tuesday, December 6: A low pressure system will move through Ohio, enhancing vertical mixing in the atmosphere and producing easterly winds at the surface. These conditions will disperse pollutants, keeping AQI levels Good. Wednesday through Friday, moderate to strong westerly winds behind the departing system will keep pollutants well dispersed, yielding Good AQI levels on all three days. Saturday, as a high pressure system moves over Ohio, winds will weaken, reducing pollutant dispersion. However, pollutant carryover from the previous days will be low. Therefore, AQI levels will remain Good.
