For many years carpets have been seen to be the enemy in regards to allergies, allergens and asthma. In the past people suffering from asthma were advised to dispose of all carpets in their home due to them trapping allergens in their fibres, and in turn this would exacerbate suffers symptoms. It has now come to light through recent studies that the truth may be the complete opposite.
In 2002 the Journal of Allergy and Clinical Immunology 110:285-92 published the results of the European Community Respiratory Health Survey. Over 19,000 participants took part from 18 different countries. The study looked at the association between household characteristics such as dampness, mold exposure and dust mite levels and asthma in adults. The results found that; “fitted carpets and rugs in the bedroom were related to fewer asthma symptoms and bronchial responsiveness.”
In 2005 a German study found that “In a room with a bare floor, the risk of more airborne fine particulate rises, while the use of wall-to-wall carpeting minimises this risk." This study conducted by the German Allergy and Asthma Society revealed that instead of being detrimental to people with asthma by holding in allergens, that it is in fact beneficial because as the carpet holds them in they are not floating around the room. Allergens on hardwood and smooth surfaces are able to move freely.
Another followed in 2008 by toxicologist Dr. Mitchell W. Sauerhoff, Ph.D., DABT, titled Carpet, Asthma and Allergies - Myth or Reality?. This study investigated 8 different countries, over a 19 year period. The conclusion to this study was that; “carpet does not cause asthma or allergies and does not increase the incidence or severity of asthma or allergies symptoms”.
