Clearly household dust is not only unsightly, but a true health hazard to families
. Simply improving ventilation by doing things like opening windows is not effective as a lot of dust comes from contaminants in the outdoor air. A high quality air purifier with a large HEPA filter and a strong fan motor placed strategically in certain areas like living rooms and bedrooms can greatly reduce the amount of dust that accumulates. Even with an air purifier, dusting, vacuuming, and washing of linens should be a part of every home's cleaning routine.
