| Studies show carpeted
rooms have lower levels of dust borne allergens than rooms with hard surface floors.
Research on carpet
In 2002, two schools in North Carolina were the subject of a study conducted by Research Triangle Institue (RTI) and University of North Carolina (UNC) investigators. One school had mostly resilient tile floors, while the other was 70-75% carpeted. The study found that airborne contaminants, possible sources of allergens, were higher over the tiled floors than over carpet.
Other studies, including one using Computational Fluid Dynamics (CFD), have reinforced these findings and concluded that carpets actually reduce exposure to particulates and potential adverse health effects.
