Air quality

Wildfire smoke creates fine particulate matter that can linger in the atmosphere and spread from coast to coast. According to the US Environmental Protection Agency (EPA), in large quantities, this microscopic dust is linked to cardiovascular disease also associated with smoking cigarettes. The EPA measures regional air quality index (AQI) by how hazardous it is to the general public. Discover the AQI in your city by searching below.
