Studies have shown that properly cleaned and maintained carpet not only reduces asthma and allergy problems, it's actually the best flooring for people who suffer from them.

What you should know
  • There is no scientific study linking the rise of allergy and asthma to the use of carpet. Indeed, several studies actually disprove any correlation.
  • A 15-year Swedish study found no link between carpet usage and the incidence of allergy or asthma. In fact, when carpet usage in Sweden decreased by 70 percent, allergy reactions in the general population increased by 30 percent.1
  • An 18-nation study of nearly 20,000 people found a statistical relationship between carpeted bedrooms and reduced asthma symptoms and bronchial responsiveness.2
  • A 2003 study of more than 4,600 school children in New Jersey found that having carpet in a child's bedroom was associated with fewer missed school days and less need for asthma medication. If carpet helped the children, it can certainly help adults in the same home as well.
