Those of us who live in a major city or urban environment know how bad the air can get. Vehicle exhaust, industrial plants, and contaminants carried on the wind pose a health threat to many today. Having a way to remove unhealthy air-borne contaminants in your home may be wise if not essential to insure your survival. This is especially true if you are sensitive to what may be in the air. Air Purifiers generally help reduce airborne dust mite debris, animal dander, mold and mildew spores, smoke, pollen and dust, so you and your family can breathe easier.
