Air Purification System

The Whole House Solution

Field Controls offers a complete line of UV-Aire products
for any home or business, with a variety of duct-mounted
UV-Aire models designed for forced-air heating and
cooling systems. UV-Aire germicidal lamps continuously
attack airborne mold, bacteria and viruses as they circulate
through your ductwork.

For homes and businesses without a forced-air system,
Field Controls manufactures two portable models. The
portable models combine the purifying power of UV
with high efficiency filtration and carbon filtration to
reduce dust, pollen, odors, and Volatile Organic
Compounds (VOCs).

The UV-500C and UV-1500C provide concentrated UV
germicidal protection in bedrooms, living rooms, and
offices… where it’s needed most. Each portable model
utilizes a motorized fan with multi-speed control to quietly
and efficiently circulate and treat indoor air. The UV-500C
is recommended for rooms up to 500 square feet, while
the UV-1500C can purify areas up to 1500 square feet.

For those who require extra protection, the 24/7 benefits of
the in-duct models can be enhanced with the concentrated
power of the portable units. The combined use of portable
and in-duct models is an extremely effective whole house
solution. This approach is recommended for anyone with
allergies, respiratory illnesses such as asthma, or a
compromised immune system*.

With 40-75 air changes per day during normal operation,
the cumulative effect of UV-Aire in-duct models reduces
airborne bacterial concentrations. UV-Aire works in
combination with a quality filter. An upgraded media filter

(MERV 8 or higher) is recommended. Filters trap larger
particles, allowing microscopic organisms to pass through
where they are zapped in the UV-Aire treatment zone.

Indoor Air: High Concentrations of
Biological Contaminants

With tighter building construction in recent years, the
quality of indoor air has declined dramatically.

The air circulating in the ductwork of the average
home or office can be concentrated with contaminants
including molds, bacteria, viruses, and dust mites.
We fill our lungs up to 20,000 times each day. Over
time, these contaminants can cause inflammation of
the mucous membranes, upper respiratory problems,
asthmatic conditions, headaches, and flu-like symptoms.

Filtering systems offer little or no help because these
airborne contaminants either pass through the filter or
simply collect on the filter medium, creating a breeding
ground. Now, with the UV-Aire

®

Air Purifying System, a
solution is available to directly address the problems
associated with poor indoor air quality.

The Sun: Nature’s Outdoor Air Purifier

For years, scientists have known that one of the most
effective air purifiers is natural sunlight. Not the light we
see when we look out the window, but the invisible “C”
band, ultraviolet rays that make up part of the sun’s light
spectrum. The sun’s UV-C rays act as a natural outdoor
air purification system, inhibiting the growth and
reproduction of bacteria, viruses, fungi, molds, and dust
mites. However, this natural process does not occur
indoors. Ultraviolet radiation (UV-C) replicates the natural
outdoor purification system of the sun by destroying the
illness and disease-causing microbes living and
multiplying in indoor air. In combination with a quality
filter, it is the most effective way to reduce airborne
contaminants and the health risks they represent.

Bacteria

Eliminate Moisture Problems

Excessive moisture under a house can

contribute to air pollution inside the

house. The Eliminator®Foundation Vent
Fan is a motorized fan designed for circulating outside
air through the crawl space of a structure to reduce
moisture and moisture-related problems. In addition to
dry rot, fungus growth and increasing termite potential,
excessive moisture can generate mold. Mold and mold
spores can infiltrate the living space as well as the
HVAC system, causing problems for the inhabitants.

With the Eliminator, air changes are increased
dramatically for better moisture removal and control.
The EL-1 is designed to be mounted to a crawl space
vent. It operates off a temperature switch which
activates the motor at or above 50°F. An optional,
adjustable de-humidistat can be used to activate the
unit at varying levels of relative humidity. This optional
control can be wired in place of, or in series with, the
standard temperature switch.

Facts About Indoor Air

Facts About UV

• According to the Environmental Protection Agency,
the air in homes can be up to 100 times more
polluted than outdoor air.

1

• The National Academy of Sciences Institute of
Medicine reports that exposure to indoor pollutants
is a key contributor to the asthma problems of
this nation.

2

• Most allergy and asthma sources are passed from
person to person through the air.

• The air in a single room can contain hundreds of
thousands of infectious bacteria, viruses, fungal
spores, and contaminants, which can only be seen
with a microscope.

• Health effects may show up immediately, or after
years of exposure to poor indoor air quality. These
symptoms include some respiratory diseases, heart
disease, and cancer. They may be severely
debilitating or fatal.

SUPPLY

UV-Aire uses the energy from a specially designed,
high-intensity UV-C lamp to reduce microorganisms in
the entire home as they cycle through the HVAC system.
Mounted inside the ductwork, the UV-Aire sterilizes or
kills most contaminants as they pass the lamp.

The process requires very little maintenance and costs
just pennies a day to operate. The UV-Aire could be one
of the best health and comfort investments a
homeowner ever makes.

Indoor Air Treatment With UV

UV’s effectiveness in killing bacteria is directly related
to a microorganism’s exposure time. Indoor air in a
typical residential forced-air HVAC system will be
recirculated 40-75 times a day. With a UV generating
lamp mounted in the HVAC duct, cumulative exposure
can be very effective in controlling indoor bacteria.

UV rays will also kill germs that breed in drain pans
and A-coils. Properly positioned, an ultraviolet system
can significantly reduce indoor air contamination and
prevent the growth of new microorganisms.

The treatment of indoor air with ultraviolet radiation
has been successful in health care facilities, food
processing plants, schools, laboratories and other
applications. It is safe, silent, and proven.

Since direct exposure to UV light can cause skin
cancer and blindness, the most practical application
of UV light in the home or office is in the main air
distribution (heating and/or air conditioning) system.
As UV light will not pass through metal, glass, or
plastic, a UV light can be installed in the main supply
or return duct of a central heating or air system
without concern for direct exposure to eyes or skin.
This is an ideal location since the air in the home or
office will pass through the HVAC system up to 75
times per day during normal operation, and as many
as 150 times per day in continuous fan mode.

The majority of indoor air is conditioned by forced-air
heating and cooling (HVAC) systems. Standard fiber
air filters are entirely ineffective in trapping germs, as
most particles are simply too small, passing through
the porous filter. New, high efficiency style filters will
only capture airborne bacteria down to a certain size.
These high efficiency filters are nominally effective,
trapping small airborne contaminants on the filter,
creating a breeding ground where germs can continue
to grow and multiply.

HVAC systems are a dark and damp breeding ground
for mold and bacteria, particularly at the system filter
and air conditioning A-coil. The buildup of matter on
the A-coil and filter can significantly reduce the
efficiency of the appliance by constricting and reducing
air flow. This means increased cost to the homeowner
in addition to the risk of airborne pollutants.

Air Purification System

For many years, ultraviolet light has proven effective in
sterilizing medical equipment, purifying water, and
processing food. Currently, the use of UV lights is
gaining industry acceptance in HVAC applications.
Microbe Management, Inc., a testing agency in

Greenville, NC, has conducted three separate tests to
examine UV’s effect on indoor air quality. The test
results conclude that UV is an integral part of a whole
house approach to improving Indoor Air Quality.

While experts disagree on the root causes of many IAQ
problems, there is consensus that stopping problems at
the source is crucial to long-term air quality
improvement. First, the homeowner must
eliminate any unwanted sources of
moisture in the home, such as roof
leaks, drainage problems, and crawl
space moisture.

The air conditioning coil must be addressed since it is a
natural breeding ground for molds, which thrive in a

dark, moist environment. Familiar with the rank smell

generated when switching from air

conditioning to heat mode? That is the

smell of mold and bio-film burning off

the coil. Whenever the blower is

engaged, mold spores from
contaminated A-coils are released

into the ductwork and distributed

throughout the building. These spores

then seek alternative surfaces in other

parts of the home to breed and multiply.

Attack the Source

Surface Test: UV Kills and Prevents Mold on A-Coils

Independent Lab Testing

EL-1 Eliminator
Foundation Vent Fan

A specific test was designed to determine UV’s
effectiveness in treating mold on coil surfaces. The
test simulated the damp, dark settings where A-coils
are found.

In this study “We took a standard A-coil, sterilized it,
introduced two kinds of mold, and then placed it in a
controlled, moisture-laden environment,” says Bernard
Kane, of Microbe Management. “We created two separate
chambers in our lab. One chamber was bathed in UV
light. The other was not.”

The results were dramatic and conclusive. The side of the
A-coil that was exposed to the ultraviolet light was clean
and clear of mold growth. Mold continued to grow

unabated on the
side without UV.
Subsequently, the
contaminated side
was bathed in UV
light and the
mold was
eradicated. Kane
summarized the
results: “Properly
positioning a UV lamp
over the A-coil in a residential or commercial air
conditioning system can eliminate surface mold on the
coil and prevent future mold growth as well.”

Surface Test Results

Note: Crawl space moisture can
be addressed with the EL-1
Eliminator Foundation Vent Fan.

Bacteria and viruses are introduced into the building by
its occupants and often cannot be controlled at the
source. Therefore, it is important to attack these
airborne invaders early and often, before they have an
opportunity to multiply. The single pass test proves that
UV effectively kills these airborne microorganisms in
the duct.

Since HVAC systems typically re-circulate the air 40-75
times per day, a multi-pass, cumulative test was also
conducted. Results demonstrate that repeated, multi­pass exposure to UV light dramatically reduces the
concentration of bacteria and viruses throughout
the home.

Air Purification System

To further investigate the effectiveness of UV on indoor
air quality, Microbe Management created a series of
tests designed to measure the cumulative effect of UV in
reducing airborne contaminants. The tests were
performed in a structure with two isolated 8’ x 8’ x 8’
rooms where air could be sampled. In the control room,
no UV was present, while the
other room utilized a portable
UV air purifier.

According to Bernard Kane,
Ph. D., of Microbe Management,
“Test results were very
encouraging. In both rooms, we
introduced a resistant, spore­forming bacteria until the air was
saturated with 350 colonies per
cubic foot. In the room with the
portable UV unit, the spore count

was reduced by 50% in just 10 minutes and by 98%
within 30 minutes. In the control room, without UV, more
than 85% of the bacteria were still active after thirty
minutes.” Similarly, the leading consumer UV “tower”
model was also tested, but showed only minimal
effectiveness. (See chart below.)

Cumulative Tests: Multiple Exposures Dramatically Improve IAQ

A-coil irradiation, single pass, and cumulative tests
confirm that UV is an important and effective contributor
to a healthier home environment. UV technology used
with a quality filter (MERV rated 8 or higher) will
dramatically improve Indoor Air Quality. Additionally,
portable units can be used in combination with in-duct
models. This combination is strongly recommended for

individuals with depressed immune systems, asthma,
allergies, or other respiratory conditions. For homes
without forced-air, portable UV air purifiers are
recommended to enhance IAQ. Also, health care
professionals, teachers, and day-care workers can
benefit from additional UV protection from influenza
and other viruses.

Conclusion: UV Is An Effective Part of “Whole House” Solution

This study introduced a common bacterium into a
galvanized air duct equipped with a UV light to
determine how effective the lamp would be in reducing
the bacteria with one exposure, or a “single pass.” The
tests were conducted at two speeds: 1125 cfm and

2250 cfm in an 18” x 18” duct. The UV lamp yielded at
least a 90% reduction of the test bacteria with a single
airflow pass at 1125 cfm, and at least 71% reduction at
2250 cfm.

UV dose is measured in microwatt
seconds per centimeter squared
(µW-sec/cm2). The information
presented is intended to give the reader
a general idea of how UV disinfects,
based upon various credible resources.
We do not guarantee its accuracy in
any way.

The Bird Flu Virus is a type of Influenza. Since the kill rate
for the influenza virus is 6,600 microwatts of UV energy, it is
reasonable to conclude that the Bird Flu virus can be
reduced or eliminated by 6,600-10,000 microwatts.

Bird Flu Virus (Avian Flu)

Most, if not all bacteria can be destroyed by the
use of UV light. The main factors in disinfection are
the amount of UV power the lamp produces and
the length of time the bacteria is exposed to the UV
light source.

The energy required to kill microorganisms is a
product of the UV light’s intensity and exposure
time. This energy is measured in microwatt seconds
per square centimeter.

Intensity x Exposure Time = microWatt seconds/cm

2

Table 1 lists the amount of UV energy (measured in
µW-sec/cm2) necessary to destroy various bacteria.

Independent lab testing of the UV-Aire shows that
in a single-pass air flow test, one 18-inch UV-Aire
lamp can reduce levels of Serratia Marcescens (a
typical bacteria) by 93%, while a two lamp system
can reduce by 99%.

1

The calculated average UV energy output levels of
a single UV-Aire lamp in an 18-inch square duct is
2,608 µW-sec/cm2 and 6,186 µW-sec/cm2for a
two lamp system. The 6,186 is comparable to the
99% energy required for Serratia Marcescens. It
can be seen that there is a direct correlation
between the UV-Aire UV lamp output and the
observed kill rates in the lab.

Correlating The Lab Test With Other Bacteria

Use the chart below to estimate the effectiveness of
the UV-Aire with other bacteria.

Harder–to–kill bacteria and molds require greater
energy or exposure time to be as effective. For
example, 99% reduction of Rotavirus requires
24,000 µW-sec/cm2of UV energy versus 6,600
µW-sec/cm2for Influenza virus (see table below).
This means that Rotavirus spores are five times
more resistant than Influenza. Consequently, spores
will require five times the UV output energy from
the lamp or five times greater exposure time. For
practical purposes, we recommend trapping the
spores in a high efficiency filter downstream of the
UV-Aire which can be irradiated continuously with
the UV-Aire lamp.

For details of the lab test ask for form number 4291.

It is important that lamps be replaced when the ultraviolet output falls below minimum requirements for protection.
Even though a lamp will appear to be operating effectively because it still maintains the visible blue glow, the
ultraviolet output will be significantly reduced after 9000 hours of use. To maintain maximum benefits,

lamps should be replaced annually.
