UV AIRE - AIR PURIFICATION
Installed directly inside forced-air ductwork, UV Aire
silently and effectively reduces airborne contaminates.
The Sun: Nature’s Outdoor Purifier
For years, scientists have known that one of the most effective air purifiers is natural sunlight. Not the light we see when we look out the window, but the invisible “C” band, ultraviolet rays that make up part of the sun’s light spectrum. UV-C light inhibits the growth and reproduction of germs: bacteria, viruses, fungi & mold. The sun acts as a natural outdoor air purification system, controlling airborne bacteria with ultraviolet rays.
Indoor Air: High Concentration of Biological Contaminants
Biological contaminants in indoor air account for over 50% of home allergies, according to the World Health Organization.
Asthma and allergy sufferers must endure constant bombardment by molds, dust, and spores. Even worse, inhaling airborne bacteria and viruses can cause sicknesses ranging from allergies to tuberculosis, and are actually the cause of death to an estimated 8.5 million people annually.
Facts About UV
Ultraviolet energy waves, invisible to the human eye, are lethal to the microorganisms found in indoor air. UV’s effectiveness
is directly related to intensity and exposure time. Also, to destroy microorganisms, UV rays must strike the contaminants directly. UV light penetrates the microorganism and breaks down molecular bonds causing cellular and/or genetic damage. The germs are either killed or sterilized, leaving them unable to reproduce. In either case, live bacterial counts can be significantly reduced and kept under control.
Filter Systems Alone Don’t Solve the Problem
The majority of indoor air is conditioned by forced-air heating and cooling (HVAC) systems. Standard fiber air filters are entirely ineffective in trapping germs, as most particles are simply too small, passing right through the porous filter. New, HEPA style filters will only capture airborne bacteria down to a certain size. These HEPA filters are nominally effective, trapping small airborne contaminants on the filter, creating a breeding ground where germs can continue to grow and multiply.
HVAC systems are a dark and damp breeding ground for mold and bacteria, particularly at the system filter and air conditioning (A/C) coil. The buildup of matter on the A/C coil and filter can significantly reduce the efficiency of the appliance as the airflow is constricted and reduced. This means increased cost to the homeowner on top of the risks of airborne pollutants.
Indoor Air Treatment With UV
UV’s effectiveness in killing bacteria is directly related to a microorganism’s exposure time. Indoor air in a typical residential forced-air HVAC system will be recirculated over 50 times a day. With a UV generating lamp mounted in the HVAC duct, cumulative exposure can be very effective in controlling indoor bacteria. UV rays will also kill germs that breed in drain pans and A/C coils. Properly positioned, an ultraviolet system can significantly reduce indoor air contamination and prevent the growth of new microorganisms.
The treatment of indoor air with ultraviolet radiation has been successful in health care facilities, food processing plants, schools, laboratories and other applications. It is a safe, silent, and proven method of improving indoor air quality.
