There may be insect fragments, lead dust, pesticides, pollen, dust mites, animal dander, hair, human skin flakes, fungal spores, or cigarette ash in household dust. Around 30 to 40 percent of the contaminants inside your home are brought in from outdoors. Dust gets into your home on shoes and clothing, or pets can track contaminants in on their paws and fur. Not surprisingly, the greatest concentration of household dust is found in carpeting near the entryway. The first four steps you take inside your front door bring in close to 85 percent of the outdoor contaminants found inside your home. By taking a few simple steps you can improve the health of your home and reduce the time spent cleaning.
