Check Air Quality - AQI helps you protect your health by providing real-time Air Quality Index (AQI) information based on your current location. Air quality levels can change during the day due to increased air emissions, such as rush hour traffic, industrial activity, or nearby wildfires. Stagnant weather conditions like temperature inversion or low wind speeds can also prevent pollutants from dispersing, leading to higher concentrations in local areas. When the AQI is predicted to rise due to fine particle pollution, public health agencies may: Advise sensitive groups, such as children, the elderly, and those with respiratory or heart conditions, to limit outdoor activities. Declare “Action Days” to encourage voluntary actions that reduce emissions, such as using public transportation. Recommend wearing masks to help prevent fine particles from entering the lungs. Key Features Check real-time AQI for your current city. Display accurate, up-to-date air quality data for your selected location.
