Did you know your carpet actually acts as a filter for the air in your home? Your carpet doesn’t just collect soils, it also traps pollutants like dust, dust mites, smoke, skin flakes, and pet dander. In fact a home with a clean carpet will likely have better air quality than a hard-floor home. Conversely, because carpets do collect indoor pollutants they need to be thoroughly cleaned every 6 to 12 months. Regular vacuum maintenance is critical to a healthy carpet but is limited to the amount of soils that can be extracted. In order to remove soils that bond to fibers in your carpet, relative pH cleaning solutions are required along with very hot-water and high vacuum extraction. There actually is a science to carpet and upholstery cleaning.
