Most people take the indoor air for granted and assume it is safe, clean and breathable. According to the American Medical Association, 50% of all illness is caused or aggravated by polluted indoor air. The air in today's buildings can contain different organic contaminants such as bacteria, viruses, mold, fungi and spores. Bioaerosols are the airborne microbes, their fragments, toxins and waste products. Numerous studies have found high concentrations of such contaminants in the air handling equipment and in the air inside the places where people live and work. These pollutants can make the air quality less than desirable, may even cause unhealthy effects ranging from allergies to tuberculosis, and are actually the cause of death to an estimated 8.5 million people annually.

Some studies state that UV light will eradicate any kind of organic contaminants from the indoor air. This is why the indoor air quality in public buildings has been addressed by specific requirements of UV light installation inside the HVAC systems. When the problem of residential air quality became apparent, ultraviolet technology became the proven answer to effectively controlling airborne pollutants. The american-lights® UV Air Cleanser can reduce or virtually eliminate all DNA based air pollutants that regular filtering systems do not catch.
