Electromagnetic Germicidal Irradiation.
Airborne Pathogen Sanitation.
There are 3 types of ultraviolet light, UV-A, UV-B, and UV-C. Many people have heard of UV-A and UV-B because we use sunscreen & sunglasses to protect ourselves from that part of sunlight. UV-C, the third type of UV light, has germicidal properties. Germicidal lamps have been used for years in hospitals, water treatment facilities, food processing plants, and other places where the strictest standards of air quality must be met. Now, you and your family benefit from the same technology in your home AC system. UV-C germicidal lamps damage/breakdown the DNA of bacteria, viruses and other pathogens so that they die when they try to reproduce. They are effective in controlling allergens, viruses, bacteria, yeast, and mold that may be in the home. The germicidal lamps generate a negligible amount of ozone and are not damaging to human beings. When used in combination with a good filter system, they keep the A/C coil and ducts cleaner that a filter alone can do. Many people find them effective in relieving cold & allergy systems as well as household odors.
Remember to change your air filters on a regular basis (monthly recommended). Needing to change your air filter more often than once a month may indicate an air quality issue. Make sure your filter fits properly into the holder. A dirty evaporator coil in your air handler can contribute to dirty air ducts.

The Centers for Disease Control (CDC) recommends the use of ultraviolet light with the simultaneous use of HEPA air filters, both of which are offered in Surround Air multi-function air purifiers. The U.S. government now specifies that UV light should be used in air handling units to improve indoor air quality in government buildings, by controlling airborne and surface microbial growth. The Air Institute of Respiratory Education suggests UV lights be used in buildings for indoor air quality purposes, and states that may be the final line of defense against those diseases that have developed resistance to drugs, such as tuberculosis and others.
• According to the Aerobiological Engineering Dept. at Penn State University , the ultraviolet component of sunlight is the main reason microbes die in the outdoor air. The die-off rate in the outdoors varies from one pathogen to another, but can be anywhere from a few seconds to a few minutes for a 90-99% kill of viruses or contagious bacteria.
• The Centers of Disease Control (CDC) recommends UV lights in homeless shelters to prevent the spread of disease, particularly TB (tuberculosis).
• A study by Air & Waste Management Association found the combination of a HEPA air filter and germicidal UV lamp reduced bacteria by 80% in a 3072 cubic foot chamber.
