Carpet Benefits Indoor Quality
The study claims indoor carpeting is not a source of biologicals, rather, it traps and holds biologicals for easy clean up. "Carpet provides the interior environment the unique benefit of acting as a fitter for indoor air," says Judy Bates, director of research for Racine Industries, and author of the study. The study incorporates data collected over the past 10 years from studies done in homes, classrooms and a variety of public places. Factors included humidity, airborne levels of mold spores, relation of indoor levels to outdoor levels, hard surface and soft surface, and mite allergens. According to Bates, "it is an unsubstantiated myth that carpet releases dust mite allergen." Two additional studies are cited to confirm the statement, one in 1995 by Air Quality Services, and in 1996 by HOST/Racine Industries). Data collected from 28 classrooms in 12 schools illustrated airborne levels of mold spores are unrelated to carpet levels of these biologicals. And air levels were substantially lower than carpet dust levels in all 28 rooms. It also showed indoor spore levels are related to outdoor levels and when equal to or less than the outdoor levels, considered normal. According to the study, in 1995, the General Accounting Office (GAO) released a report to Congress stating one in five US schools suffer an IAO problem. The report is laced with reasons, from HVAC deficiencies to leaky roofs, but carpet was not mentioned. Bates concludes maintenance is the key. "We are not alarmed to find dirt on a floor," she says. "Likewise, we should not be alarmed to find biologicals on a floor. They do not grow there; they only land there. Carpet only needs to be cleaned regularly -- as does any indoor surface - to continue to contribute its filtering ability." Another Racine, WI-based company, SC Johnson and Son, Inc., is getting into the IAO business. The company has begun marketing efforts for an introductory product that the company claims will remove allergens from carpets and fabrics. According to SC Johnson, the average bed in the US contains over 10,000 dust mites with millions more hiding in carpets, couches and curtains. The allergens from these microscopic relatives of spiders affect an estimated 14 million Americans. National health care organizations recommend indoor allergen control as an important step toward asthma or allergy relief. "Up until now, people had to resort to relatively impractical measures to reduce indoor allergens," says Stephen Brunton, MD, director of faculty development, Stamford Hospital/Columbia University Family Practice Residency Program. "Now my (residents) will be able to take control of dust mites in their homes simply and effectively." Racine's Bates believes the vacuum bears blame for mites remaining in carpet. "(Our study) presents the inescapable conclusion (that carpets trap and filter the air). The problem is not the removal by the vacuum, but the retention of the vacuum." |
