, wood products experts at the National Wood Flooring Association write on how wood floors improve indoor air quality:
A recent Life Cycle Analysis of wood flooring conducted by the University of Wisconsin supports this belief. The study compared five different floor coverings in regard to four substances considered to be harmful to the atmosphere: carbon dioxide, methane, nitrogen oxide and particulate matter. All these substances contribute to atmospheric warming and human respiratory ailments. The results of the study show that wood flooring had no emissions for methane, nitrogen oxide and other particulates, and minimal emissions for carbon dioxide. Wood floors also have the added benefit of not harboring allergens, microorganisms or harmful pesticides that can be tracked in from outdoors. In addition, dust, mold and animal dander contamination is minimal in homes with wood floors, which can significantly improve indoor air quality.
