The common mistake most homeowners make is not having their carpets cleaned on a regular basis because visually they appear clean. Once your carpet looks dirty, it is past the point of needing to be cleaned. It then becomes a restoration type cleaning and the soil particles can scratch the carpet fibers causing them to look dirty even though they were just cleaned.
The importance of having your carpets cleaned by a professional& certified company every 6 to 12 months is this: it improves air quality and sanitizes the carpet.
Carpet acts as a filter in your home, just as your HVAC unit has filters, your water filter in your refrigerator, etc. You change these filters on a regular maintenance basis. So why does the "carpet filter" get left behind? Carpet filters out gases, soils and human & pet dander. Not to mention allergens that you breathe in. Vacuuming only removes between 79 and 81% of the dry particulate matter in the carpet. So the rest is left behind and you breathe it in.
Now, if pets are in the house and they are scratching and rubbing around on the carpet, the carpet would need to be cleaned every 6 to 8 months. Especially if you have small children playing on the carpet.
In Conclusion to maintain a "Healthy Home Environment" for your loved ones, have your carpets cleaned on regular basis by a Professional Certified Company that uses Truck Mounted Equipment.
