IQAir classifies AQI scores between 0 and 50 as “good,” while 51 to 100 is considered “moderate.” Scores between 101 and 150 are considered unhealthy for sensitive groups, including children, older adults, and people with respiratory illnesses.
An AQI score between 151 and 200 is classified as “unhealthy,” while 201 to 300 is considered “very unhealthy.” In such conditions, children, elderly people, and those with health complications are advised to remain indoors, while others should limit outdoor activities. AQI levels above 300 are considered “hazardous” and pose serious health risks for everyone.
