How to interpret the air quality index (AQI)
According to AirNow, the higher the AQI value in your area, the greater the level of air pollution and the greater the health concerns.
AQI of 100 or below An AQI of 50 or below represents good air quality and won't pose risks. Air quality is still acceptable if the AQI is 51-100, but there may be a risk to people who are unusually sensitive to air pollution, such as those with respiratory illnesses.
AQI between 101 to 150 If the AQI is 100 to 150, people with respiratory or other medical issues should start taking precautions like avoiding the outdoors altogether or wearing a mask when outside.
AQI between 151 to 200 If the AQI is 151 to 200, most people will start noticing some minor effects like a scratchy throat, runny nose and maybe some nausea. If you're in a sensitive group – for example, if you've been diagnosed with asthma or chronic obstructive pulmonary disease (COPD) – then you'll want to look out for signs of more severe health problems, like chest tightness, an inability to catch your breath, and sudden dizziness or confusion.
AQI between 201 to 300 If the AQI is over 200 in your area – this should show as a purple color on a map – then health risks are increased for everyone, whether you have underlying issues or not. You might notice minor symptoms, such as coughing, but everyone should be alert to symptoms that might indicate a more serious problem, such as a tightening or weighted feeling in the chest or labored breathing.
AQI of 301 or above If the AQI is 301, everyone will likely experience some form of smoke-related health issue. If you can, move all activities indoors or reschedule them for another day.
