Hawaii Honolulu ranks No. 3 in U.S. air quality study By Shane Nelson / May 24, 2010 Share 1 -- The American Lung Association rated Honolulu as the No. 3 U.S. city for air quality in its recently released State of the Air Report for 2010. "We have always been proud of the air quality in Honolulu," Joe Davis, SMG general manager of the Hawaii Convention Center in Honolulu, said in a statement. "One of the most common things that we hear from our guests is how the air here is scented with hints of the ocean and the sweet smell of flowers." The association studied particulate matter and ozone pollution levels over a 24-hour period and on a year-round average. Cheyenne, Wyo., earned the top spot, while Santa Fe-Espanola, N.M., came in second. Twelve cities were awarded an "A" rating.
