The IIRC says that vacuuming your carpet regularly and even taking your shoes off when entering the house can improve the health of your house and the longevity of your carpet.
How Often Should Carpet Cleaning Be Done By a Professional?
The IICRC* has stated in the Standard for Carpet Cleaning that "Consumers must 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.
