uv lights for eliminating mildew and bacteria

UV Light Systems (Mildew & Bacteria Eliminators)

What is UV light?
UV stands for Ultra-Violet light. Ultraviolet light represents the frequency of light between 200 nanometers (nm) and 400nm.
What does a UV light do?
A germicidal UV light system can significantly reduce the amount of viable airborne micro-organisms found in HVAC units. UV light eliminates molds, bacteria, yeasts, and viruses. These are naturally occurring contaminants that infiltrate every home and office on this planet. Micro-organisms are living creatures that are so small a microscope is required to view them.
How does it work?
UV light penetrates the cell walls of the microbe, causing cellular or genetic damage. The affected microbe is neutralized or becomes unable to reproduce. Intensity and exposure time will determine how quickly a susceptible microbe is disabled by UV light.
What are the primary benefits?
UV lights will significantly reduce the amount of microbes in ductwork and air space, helping to reduce possible health problems associated with inhaling microbes. UV light is also beneficial in keeping air conditioning coils free of mold which increases system efficiency.
How would I further benefit from improved indoor air quality?
Poor indoor air quality is a problem that affects everyone. Individuals with weakened immune systems, allergies, and asthma benefit the most from improving air quality. Households with children or elderly individuals will also benefit from the improved air quality. Your HVAC air handling system can operate with more efficiency as the coils, drain pan, and ductwork stay cleaner longer.
What is the importance of UV light products for indoor environments?
Overall, people spend 90% of their time indoors, in a "closed" environment with little or no exchange of outside air. Such an environment can become a breeding ground for potentially harmful pathogens, and in high numbers, can prove hazardous to human health.
Why should I consider installing a UV light?
Indoor air can be some of the poorest quality air we experience. When we leave our windows shut, air is constantly re-circulated throughout our homes. Over time this air can become stagnant and bacteria, molds, yeasts, and viruses more concentrated. These concentrations can cause inflammation of mucous membranes, upper respiratory problems, and aggravate asthma and other breathing ailments. A germicidal UV light system assists in combating high levels of these micro-organism concentrations.
Does UV really work?
Yes. UV has been proven under numerous studies for its ability to destroy the DNA of germs, viruses, mold, mold spores, fungi, and bacteria.

In residential applications, the objective is to create a cost effective and continuous method of cleansing the air. Because UV has been proven to work on a cumulative manner, the bad air is cleansed over time and subsequent passages over the lamp. One washes his/her hands more than once a day to periodically rid ones self of germs. Germs are constantly invading our homes via people sneezing, coughing, pets scratching and from other instances. The UV technology now gives us the opportunity to clean the air within our homes continuously in a very cost effective manner.
Do I still need an air filter?
Yes. A UV light system is designed to be used in addition to a high efficiency air cleaner system or an air purifier system. However, filters are inefficient at dealing with microscopic bacteria, molds, and viruses and are incapable of preventing mold from growing on a surface. A UV light system contributes significantly to the reduction of the small microbial organisms that pass through filters and into the general air stream. Proper placement of a UV light system above the coil, or a surface area prone to microbial growth aids in reducing the amount of viable microbes on that surface.
Don’t filters eliminate germs?
Filters do trap microbes, but even the most sophisticated ones do not contain 100% of the germs. The micro-organisms not trapped will reproduce quickly and spread throughout your home. The filter can actually become a breeding ground for new microbial colonies.
What type of germs are affected?
UV light is extremely effective against virtually any airborne microbe including rhinoviruses (colds), influenza, bacteria, molds and mold spores.
How much maintenance is required on a UV light product?
There is no maintenance required with a UV light system. UV light bulbs have a service life of 9,000 hours, or approximately 375 days. Annual replacement of the bulb(s) is recommended. Most UV light systems should be left on continuously as turning them on and off ages the bulbs and power supplies.
How much electricity does a UV light use?
Each tube uses approximately the same electricity as a 75-watt light bulb.
How many lamps do you recommend for residential installations?
We recommend two lamps. Each installed and positioned to bathe each side of the indoor evaporator coil.
Has UV technology been tested?
Yes. Westinghouse Electric, General Electric, and Penn State University conducted laboratory tests on the effectiveness of UV light on micro-organisms. UV light has also been used in wastewater plants and commercial settings for over 60 years.
