This article was published on August 30, 2001 by the Carpet and Rug Institute (CRI). They are an industry trade association committed to educating people about carpet and to dispel untruths and myths.
"The suggestion that carpet causes indoor air quality problems is a significant issue for the carpet industry to address." said Werner Braun, president of CRI. He continues, "Through research, CRI offers information that is valuable to medical professionals and to anyone living with carpet."
The following myths have been identified as the top ten most persistent misconceptions, according to Mr. Braun.
Myth No. 1
"There are health risks associated with carpet."
|Truth:||An extensive toxicological assessment of components of carpet concluded that the chemicals in carpet pose no health risks of public concern.|
|Reference:||In 1994, Environ Corporation of Arlington, Virginia, prepared a study, Safety Assessment of Components of and Emissions from Carpets. The conclusion was: "For the chemicals identified as being present in, but not emitted from carpet, there is no reason to believe that they present any health risk of public concern. For chemicals identified as being from carpet, no cancer risk of public health
concern is predicted for any chemical individually, or when the predicted
upper limit on risk is added for all potential carcinogens. Similarly, no
non-carcinogenic effects of public health concern would be anticipated."|
Myth No. 2
"Mold and mildew can grow in carpet."
|Truth:||Mold and mildew exist ONLY where there is excess moisture and dirt coupled with poor cleaning and maintenance habits. Mold growth can occur on ANY surface (windowpanes, concrete, hard floors, carpet, furnishings, etc.) that is not properly maintained and when moisture is extreme.
Eliminating sources of excessive moisture, such as water leaks, and controlling
humidity greatly offset the potential for mold to grow.|
|Reference:||In a study conducted by HOST/Racine Industries, six Florida schools were checked for indoor air problems triggered by high humidity and reduced ventilation. Dust-lined,
moldy ducts and plumbing leaks onto ceiling tiles allowed mold to grow and released millions of spores into the air. The research supported that mold and mildew are not associated with a particular surface, such as carpet.|
Myth No. 3
"Carpet is a cause of the asthma and allergy increase."
|Truth:||Comparison data from Sweden supports that there is no link between carpet usage and the incidence of asthma or allergies. CRI is not aware of any published scientific research demonstrating a link between carpet and asthma or allergies.|
A study, based on historical figures for ten years, was reported by scientists at the Swedish Institute of Fibre and Polymer Research. They found that while the use of carpet in Sweden had steadily decreased since 1975, the occurrences of allergic reactions in the general population had actually increased.
Myth No. 4
"Carpet is a sink for allergy-causing substances."
|Truth:||This is true as stated. The critical point, however, is often missed. Carpet holds allergen-causing substances tightly and, as a result, keeps allergens from becoming airborne, minimizing the level of allergens in the breathing zone. This translates
to lower exposure potential. (Hard floors do not do that. One way to see this for yourself is to watch the air in a home when the sun is shining into the home. With clean, carpeted surfaces, you see some dust in the air, but not much. In a home with hard floors, you see more dust because there is less surface in the home that holds onto dust). The allergens held by the carpets filter-like
effect may be removed by vacuuming, refreshing the filter-like properties
of the carpet to allow more material to be removed from the air. Vacuuming mattresses, carpet, and upholstery once or twice a week removes allergens, including dust mite feces which are a known source of allergen. It is important to use the proper type of vacuum to minimize re-suspending allergens. (For hard floors, the proper dusting and mopping system is important. With just a small amount of air movement on a hard floor, allergens are swept up into the air and into the respiratory systems of occupants).|
In Carpet and
Airborne Allergens, A Literature Review, Dr. Alan Luedtke refers to
the results of a study aimed at determining the effect of routine vacuuming cleaning that indicate frequent vacuum cleaning over a short time significantly reduces house dust and mite allergen levels in carpets.
Agency (EPA) studies indicate the effectiveness of carpet in reducing
airborne particles. This data indicates that soil in carpet is significantly
reduced following cleaning. Visit CRIs web site to learn about the Green
Label Vacuum Cleaner IAQ Testing Program that approves vacuum cleaner
models that are most effective in soil removal and dust containment, while
keeping carpet looking good.
Myth No. 5
"Carpet is a source of indoor air quality (IAQ) problems."
|Truth:||As noted previously, an extensive toxicological assessment of components of, and emissions from,
carpet concluded that the chemicals in carpet "present no health risks of
public health concern". Furthermore, allergens in carpet may be removed by vacuuming.
Vacuum cleaner machines bearing the CRI IAQ Green Label meet scientifically established standards for soil removal and dust containment and help maintain
good carpet appearance.|
|Reference:||EPA/RTI Total Building Cleaning Effectiveness Study states, "Organized cleaning contributes
to reduction of particle VOCs and biological pollutants 50%+." Also referenced
is the previously mentioned 1994 report from the Environ Corporation,
Safety Assessmentof Components of and Emissions from Carpets.|
Myth No. 6
"Carpet is more expensive and harder to maintain than hard-floor surfaces."
|Truth:||Properly maintained carpet only needs vacuuming once or twice weekly and periodic extraction cleaning. The sweeping, mopping, stripping, waxing, and buffing that hard
surface floors demand are more laborious and costly.|
|Reference:||A Building Office Managers Association (BOMA) study found hard-surface floors require two-and-a-half times more annual cleaning than carpet. Consumers may request CRIs brochures Carpet, the Educated Choice for Schools, Carpet Maintenance
for School Facilities, and Use Life Cost Analysis for Commercial Facilities to learn about the life-cycle cost analysis and the value carpet delivers through warmth, comfort, safety, and acoustics in the classroom and at home.|
Myth No. 7
"Carpet is environmentally non-sustainable."
|Truth:||CRI member companies, representing over 90 percent of the industry's manufacturers, have an excellent track record over the last dozen years of decreasing wastes produced and
energy consumed, improving the industry sustainability.|
|Reference:||The Carpet and Rug Institute's Sustainability Report, 2001 details the industry's
Myth No. 8
"Carpet is a major emitter of volatile organic compounds (VOCs)."
|Truth:||Most new interior furnishings
and building materials emit VOCs for a period of time. Emissions from new
carpet are among the lowest of any household's indoor furnishings, and most
VOCs dissipate within 24 hours... even faster with good ventilation.|
|Reference:||To further minimize
other IAQ concerns, specify low-emitting products, including CRI Green Label
carpet, cushion, and adhesive, when selecting household products and furnishings.|
Myth No. 9
"Formaldehyde is used in the production of new carpet."
|Truth:||Formaldehyde is not
used in the carpet manufacturing process. It is not emitted from new carpet.|
|Reference:||An article published
in 1989 in the American Textile Chemist and Colorists Journal stated that research conducted by the School of Textile Engineering, Georgia Institute of Technology, under Dr. Wayne Tincher and other researchers dispelled
this widely-held myth. In addition, the CRI Indoor Air Quality Testing Programs
specifically monitor for formaldehyde emission from new carpet, carpet cushion,
and installation adhesives as part of the industry's assurance to the public
of the absence of this chemical in these products.|
Myth No. 10
"Latex in carpet produces allergic reactions."
|Truth:||The latex that holds the fibers and backing together in broadloom carpet is synthetic. Synthetic latex is not associated with the allergic reactions of natural latex, which are caused by the proteins found in natural latex.|
|Reference:||Carpet is made primarily of the same innocuous materials found in clothing and other everyday fabrics, including polyester and nylon.|
The Carpet and Rug Institute, headquartered in Dalton, Georgia,
is the national trade association for the carpet and rug industry. Its members
are manufacturers, suppliers, and service providers, representing over 90% of
all carpet produced in the United States. CRI is the source for science-based
information and insight into how carpet and rugs can create a better environment - for living, working, learning and healing.
When you analyze and compare all living conditions in today's world, carpet actually makes a healthier home or facility. You don't have the dust load in the air as you do with hard floors - all things being equal, of course, and cleaned accordingly.
So you have two options:
Option #1: Have carpet in the home hold onto contaminants, keeping them away from your breathing space, and remove these contaminants with regular vacuuming and professional steam cleaning or...
Option #2: Have hard floors in the home, which do not hold contaminants but instead allows them to linger in the air resulting in a higher degree of allergic reactions.
Besides being healthier for occupants, carpet also makes a safer home or facility. There are less trip and fall accidents on carpeted surfaces, and if something is spilled, there is less of a chance of slipping.
The best thing to do when it comes to deciding which type of flooring to install is to think about how it is going to be used. If you want a comfortable, quiet atmosphere - and a healthy one too - then carpet is the right choice.
