Air Purification with UV Germicidal Light

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.

Let AirCool help you determine whether a UV germicidal lamp is a good choice for you and your family.

UV Light Air Purifier Facts & Studies

The Centers of Disease Control (CDC) recommends the use of ultraviolet light with 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.

• 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.
