The Environmental Protection Agency and its Science Advisory Board have consistently ranked indoor air pollution among the top five evironmental risks to public health. Also, according to the American College of Allergy, Asthma and Immunology, 50 percent of all illnesses are caused by or aggravated by polluted indoor air.

Over 40 million Americans suffer from allergies due to home bio-pollution. If you or your child has allergies or asthma, you already know that many things can bring on, or "trigger" an asthma flare or episode. Some things that trigger asthma attacks are called allergens. Some people get symptoms from only one allergen-like dust mites. For other people, more than one kind of allergen can trigger an episode.
