Check the quality of air you are breathing
Is the air you, your family, and friends breathing healthy? Check the quality of the air where you are, in the past, and get a forecast for the coming days.
Air quality information is based on the EPAs air quality index system, which has a number of categories, colors, and ratings. These are displayed to you in a straight forward way so you can quickly understand if the quality of the air is good or harmful.
The EPA developed the AQI(Air Quality Index), which reports levels of ozone, particle pollution, and other common air pollutants on the same scale. An AQI reading of 101 corresponds to a level above the national air quality standard - the higher the AQI rating, the greater the health impact.
