If you've been living with allergies, you probably know the obvious stuff by now -- don't take in stray cats, don't hang around in dusty attics, don't inhale deeply in smoking lounges.

Other ways to keep the air clean in your home:
Wash throw rugs every week in hot water to kill dust mites and other allergens.
Use a microfiber or electrostatic cloth for dusting. They don't stir up dust or allergens.
Replace carpeting, if you can, with tile or hardwood floors.
