How often should carpets be professionally cleaned?
Most major carpet and carpet fiber manufacturers recommend carpets be professionally cleaned every 18 months in order to remove particulate soils that cause carpeting to wear prematurely and affect the appearance of the carpet. However the Environmental Protection Agency (EPA), who takes a position of the carpet being cleaned for health and not appearance, recommends that carpets be cleaned annually. However, carpets that are subjected to extreme soiling or heavy use, particularly high-traffic areas, or carpets installed in homes occupied by persons with allergies or respiratory problems, require increased cleaning frequency.
