UV Light

What UV lights are and their use:

1. How do UVC Lights work?

UVC Lights use Ultraviolet energy. UVC energy penetrates even the tiniest microbe to destroy its DNA, killing or deactivating it.

2. How are the UV Lights provided by Dusty Ducts different from other UV devices?

We use only the best UV Lights, which are developed specifically for use in A/C systems. It offers its peak performance under extreme operating temperatures, delivering up to five times the output of conventional UV lights. The result: – it has the highest microbial destruction rates, for clean, germ-free air.

3. Is it harmful in any way?

No. Dusty Ducts uses UVC Lights that destroy organisms without producing toxic ozone, fumes or secondary pollution. It poses no risk to people, furnishings or equipment. (Direct exposure to the light itself is not recommended.)

4. Is the technology proven?

Absolutely! The UV products that Dusty Ducts uses have been installed in buildings all over the
U.S.
and
Asia

– including hospitals, schools, offices, public buildings, food processing plants, electric utilities and residences.

5. Is the product suitable for people with severe allergy or asthma problems?

Yes, UVC Lights have afforded relief to people suffering from chronic upper respiratory problems. But the device is not limited to households with “special problems.” Everyone benefits from the clean, healthy indoor environment that results when your A/C system is bathed in UVC Lights’ germicidal energy.

6. How do UVC Lights produce a fresh-air smell?

Mold, mold products and decaying matter produce unpleasant or musty odors. In destroying mold, UV Lights stops these odors.

7. Is it affordable?

Some users report that UVC Lights pay for itself due to lower medical and pharmacy expenses, energy savings and the reduced need for A/C system maintenance. After the initial installation, UV Lights costs only pennies per day to operate… consuming about the same amount of energy as a 75-watt light bulb.

8. What is UVV?

UVV light refers to another wavelength in the ultraviolet spectrum. Some UV devices, offered by other duct cleaning companies, also produce light in this wavelength. The manufacturers of these devices promote UVV as an added tool for IAQ control, saying that UVV attacks microorganisms, chemicals, and odors. While this may be true, it is important to understand that UVV (unlike UVC) will also “attack” occupants in treated spaces by adversely effecting human lungs!

The reason for this is that the shorter (185 nanometers) wavelength of UVV light (used by other duct cleaning companies )actually generate ozone. This occurs because UVV light reacts with oxygen to break it into atomic oxygen, a highly unstable atom that combines with oxygen to form O3 (ozone). The American Lung Association states that “exposure to ozone causes a variety of adverse health effects, even at levels below the current standard.” And the U.S. Food & Drug Administration says: “In order for ozone to be effective as a germicide, it must be present in a concentration far greater than that which can be safely tolerated by man and animals.” The longer (254 nanometers) wavelength of UVC light offered and used by Dusty Ducts, by contrast, provides highly effective air, surface, and water disinfection without producing any harmful ozone.
