Dalton, Georgia, April 15, 2011 - A major study of inner city children with asthma concludes that positive environmental interventions in the children's homes, such as improved cleaning and the elimination of tobacco smoke, will result in a lessening of the children's asthma-related symptoms and an increase in their symptom-free days. Further, the Inner-City Asthma Study found no difference in the improvement experienced by children who lived in homes with carpet versus children from homes with other types of flooring.

In addition, no difference was found in the levels of allergens measured in carpeted homes compared to homes with hard surface floors. From the Carpet and Rug Institute.
