Indoor Air Quality has been a vital concern in the United States and the world since twenty nine members of the American Legion died following attendance at a convention held at the Bellevue Stratford Hotel in Philadelphia in 1976. Since then, numerous buildings have been closed or renovated because of indoor air concerns. Here are some additional facts about the current status of indoor air:
