Air pollution can be a problem anywhere, not just in areas of high population or industry. That is why there are over 2,600 EPA air quality stations across North America. It is important for people everywhere to easily find and understand air pollution levels. Unfortunately, most people remain unaware of their local air quality because the data is not accessible or approachable. Air Lookout aims to change that.
Please Note: Air Lookout currently only supports the U.S. Environmental Protection Agency's air quality stations in North America.
