UV-C Germicidal Lighting
UV-C Germicidal Lights Reduce Mold, Allergens, and
other Biological Contaminants in Your Home
Indoor Pollutants in your Home
Most people spend the majority of their time inside their homes. The EPA warns that the air
inside your home may be up to 5 times more polluted than outside air. Microscopic mold,
mildew, bacteria and viruses linger in the air leading to allergies, asthma, respiratory disease
and infection. These unseen biohazards can live and breed within can pose a serious health
Mold thrives in the cool damp environment of the air handling system. Mold growth on cooling
coils and the interior of the air handler is not only a health risk, it can significantly reduce the
efficiency of the system.
Ultraviolet light is that portion of the electromagnetic spectrum that lies beyond the purple
edge if visible light. The UV-A range causes "sun tanning" in human skin. The UV-B range
causes "sun burning". Natural UV-C range light from the sun is filtered out by the
atmosphere. Scientists have known the germ killing power of artificially created UV-C light
for years. The antimicrobial power of UV light is used in water treatment facilities, in the food
industry, and in hospitals where it is used to clean the air and reduce the threat of airborne
infection as well as to disinfect surfaces and surgical instruments. Today this powerful
disinfecting technology is available for our homes and businesses resulting in healthier,
safer, indoor environments.
Kill Germs With Light
For over a century scientists have known that certain frequencies of light have a devastating
effect on microbial life. We now know that exposure to ultraviolet light in the range of 254 NM
(UV-C band) disrupts the DNA of micro-organisms thus preventing them from reproducing,
thereby effectively killing them.
UV Light- A Well Established Disinfection Technology
UV light disinfection is now widely used in hospitals and laboratories to sanitize instruments
and work surfaces and to prevent the spread potentially lethal airborne infectious diseases.
The technology is used by the food industry to sterilize food before packaging and water
treatment systems large and small now incorporate UV light as a chemical-free means of
A Cleaner Air Handler
Installation of a germicidal UV light inside the air handler inhibits the growth of mold there
which saves energy by allowing the system to operate more efficiently. A cleaner system also
requires less maintenance.
Germs in the Air You Breathe
Like it or not the indoor air you breathe has a lot of stuff in it that you don’t want. Like viruses,
bacteria, mold, mildew, and allergens. Some are only annoying, others can make you sick.
Because air passes repeatedly through your HVAC system (in fact many microbes like the
cool dark damp interior of the system) this is the ideal place for germs to multiply and spread
throughout the house.
A Whole-House UV Air Purifier - The Best Defense
Because it works inside your central air system a whole-house UV air purifier is able to
intercept airborne pathogens and destroy them as they pass by. As air cycles through the
system it passes by the UV light many times exposing and re-exposing airborne microbes to
it's sterilizing effect. This has proven to be a safe, economical, chemical-free way to
significantly reduce airborne contaminants indoors.

UVC-applications. Products like AHU Series® feature simple installation in the air handler.
The innovative APCO™ in-duct air purifier also reduces toxic Volatile Organic Compunds (V.O.
C.s) in the air.
