This article explains possible effects of carpeting on indoor air quality in homes, including the emission of VOCs, formaldehyde styrene, and odors from other sources such as carpet mold. This article includes excerpts or adaptations from Best Practices Guide to Residential Construction, by Steven Bliss, courtesy of Wiley & Sons. Also see ASBESTOS in CARPETING, PADDING.

As discussed in Best Practices Guide to Residential Construction:
Concerns about the health effects of carpeting first gained national attention in 1988 when new carpeting installed at the EPA headquarters in Washington, D.C., was linked to a rash of health complaints among EPA staff. While a definitive cause never was identified, experts focused on two main compounds:
Styrene, a known health hazard and suspected carcinogen, is also found in the latex backing on carpeting.
Since 1988, over 500 people have made complaints to the Consumer Products Safety Commission (CPSC) about new carpeting. The most frequently reported symptoms have been watery eyes, runny nose, burning sensation in the eyes, nose, and throat, headaches, rashes, and fatigue. In response, the CPSC commissioned a study of off- gassing from new carpeting and identified 31 compounds, but none approached airborne levels known to be hazardous for short-term exposure.
Long-term effects of exposure to these carpet-associated chemicals or gases were not studied.
While some suspected formaldehyde (see Formaldehyde Hazards), a common respiratory irritant, it has not been used in the manufacture of U.S. carpeting since the late 1980s (with the exception of some vinyl-backed carpet tiles used in commercial installations).
See STAIN DIAGNOSIS on BUILDING INTERIORS and STAINS on & in BUILDINGS, CAUSES & CURES and STAINS on INDOOR SURFACES: PHOTO GUIDE as well as STAINS & Thermal Tracking. See Black stains from animals for details about pet stains on building floors (urine) and walls (various) and see Pet Stains on Walls for diagnosing stains such as the black marks left by pets on walls. Readers should also see STAINS on Indoor Surfaces: PHOTO GUIDE and for outdoor stains, see STAIN DIAGNOSIS on BUILDING EXTERIORS
Carpet Labeling Program Identifies VOCs, styrene, 4-PC & Formaldehyde
Labeling Program for Carpet Padding & Carpet Adhesives
Air Out Carpet Before Installation or Occupancy
Both CRI and independent health advocates agree that new carpet emissions drop off rapidly in the first 24 to 72 hours after being unrolled and exposed to ventilation air.
By increasing ventilation during that time, or if possible, airing out the carpet for several hours to several days before installation, most of the chemical emissions can be avoided. In glue-down installations, seek out low-VOC adhesives rated at less than 50 grams of VOC content per liter of adhesive.
Carpeting Alternatives for Sensitive Individuals.
Once installed, carpets can act as reservoirs for contaminants filtered from the air or tracked in on shoes, including hydrocarbons, pesticides, and other particulates.
Also, in high-humidity conditions, dust mites, a powerful allergen, can thrive in carpets. In homes with small children, people with allergic conditions, or high-sensitivity individuals, consider alternatives to carpeting. Area rugs that can be washed periodically in 130°F water are an option. Where carpeting is installed, health experts recommend frequent vacuuming with a HEPA-type vacuum or central vacuum with an outside exhaust, and periodic deep cleaning using a hot-water extraction system.
