Wall-to-wall carpeting and large area rugs in the family or living room can harbor dust mites and mold. Dust mites and mold are common asthma triggers. To minimize exposure to these biological contaminants, carpeting and rugs should be vacuumed at least once a week. The American Lung Association (ALA) advises using central vacuum systems or a high efficiency particulate arrestance (HEPA) vacuum cleaner.
Homes built on a slab foundation should avoid laying carpet directly on concrete. Damp or moist conditions promote the growth of mold on the concrete′s surface and in the carpet. If carpeting becomes wet, it should be cleaned and dried by a professional carpet cleaning service.
In addition, new carpeting may emit a gas or chemical odor for several weeks or months. Chemicals found in glues and adhesives may "off-gas" as well. Breathing gases and chemicals such as these are often irritating to the eyes, throat, and lungs.
