Many household items give off chemical vapors that can impact your family’s health. The list includes carpeting, upholstered furniture, gas appliances, paints and solvents, cleaning products, air fresheners, dry-cleaned clothing and pesticides. If you have an attached garage, fumes from the gasoline, oil and antifreeze in your car can find their way into your home’s air. Harsh chemicals can also come from cigarette smoke and woodstoves.
