The IICRC* has stated in the Standard for Carpet Cleaning that “Consumersmust not wait until carpet looks soiled before cleaning. Experts agree that clean carpet contributes not only to the overall aesthetics of a structure, but plays a significant role in the healthful state of the overall environment in which people spend the majority of their time.”
The United States EPA in a letter dated January, 1989 (referenced in the IICRC Carpet Cleaning Standard*) included the following information to serve as a guideline for cleaning frequencies for carpet from a health perspective.
|Normal Conditions||Dusty Outside||Cold Weather Climates||High Humidity Climates|
|2-People, Non Smoking||6-12 months||2 months||4-6 months||4-6 months|
|2-People, Smoking||4 months||2 months||3 months||4-6 months|
|With Young Children||6 months||1 month||3 months||3 months|
|With Young Children and Pets||3-6 months||1 month||2 months||2 months|
*What is the IICRC Carpet Cleaning Standard? This Industry Standard was developed to define the minimum standards for carpet care by a task force with input from DuPont, the EPA, Shaw Industries, ASCAR, BASF Fibers, the Carpet and Fabricare Institute, the Carpet Manufacturers Association, S.C. Johnston Wax, Monsanto, Miliken, and others for the Institute of Inspection, Cleaning and Restoration Certification (IICRC).
