Did you know that carpet acts as a filter in your house?
Carpet actually traps dust and pollen into its fibers unlike hard floor surfaces. As you walk around these pollutants are stirred up in your home. Have you ever notice the dust bunnies gathered in corners of your hard floor but not in your carpeted rooms? With carpet you can do a regular vacuuming to remove the dust and pollen.
Then, at least once a year have your carpets professionally cleaned (more often for heavy traffic locations or homes with children and/or pets as well as commercial locations such as an office).
