Air: Elevated Concentration of Biological Contaminants
According to the World Health Organization, biological contaminants
in indoor air are responsible for over 60% of allergies. Allergy
and Asthma sufferers are continually exposed to attacks by
mold, bacteria, dust, and spores. Even worse, inhaling viruses
and airborne bacteria can cause sicknesses ranging from allergies
to tuberculosis, and are in fact, the cause of death to approximately
8.5 million people a year.
An Environmental Protection Agency report states that indoor
air can contain up to 70 times more contamination than outdoor
air. While indoor air may appear clean, air in a particular
room may include hundreds of thousands of contagious bacteria,
viruses, fungal spores, and other contaminants.
Filter Systems Don't Solve the Problem
Common HVAC filters are designed to trap airborne particulates
such as hair and dust. Filters are not designed to trap microscopic
organisms. Microorganisms are too small to be trapped in most
filter systems. Even high end filters such as High-efficiency
particulate absorber or electrostatic are only nominally effective
in trapping some airborne contaminants. In some cases, the
filter can actually become a breeding ground for germs.
The sun controls bacteria outdoors by emitting ultraviolet
rays. These UV rays are a segment of the sun's light spectrum.
UV-C light inhibits reproduction and the growth of many germs
including: viruses, fungi, bacteria and mold. The germs are
sterilized or killed, making it impossible for them to reproduce.
To be effective, UV rays must directly strike the contaminants,
and sustain exposure for a particular length of time. This
process occurs naturally outdoors in the presence of sunlight.
However, this process does not occur indoors. This is why
indoor air is significantly more contaminated.
REDUCE INDOOR AIRBORNE BACTERIA AND CONTAMINATION, SEVERAL
HEALTH AND ENVIRONMENTAL AUTHORITIES ADVISE USE OF AN ULTRAVIOLET
AIR PURIFICATION SYSTEM. ULTRAVIOLET TECHNOLOGY IN COMBINATION
WITH ANY FILTER IS THE MOST EFFECTIVE MEANS OF REDUCING AIRBORNE
BACTERIA AND THEIR ASSOCIATED HEALTH RISKS.
air health brings ultraviolet
technology into the home, utilizing any warm air or forced
air HVAC system. air health mounts
in the main supply or return ductwork, constantly emitting
powerful UV rays. The home's air is recirculated over 50 times
a day during normal operation of the heating or air conditioning
system. Continued exposure to air health
reduces airborne contamination, improving the indoor air quality
of the entire home.
best location for air health is
over the A/C coil. This will treat the indoor air while simultaneously
keeping the coil clean. The moisture on the coil and in the
drain pan is a prime breeding ground for bacteria, spores,
viruses and other contaminants. If there is no A/C system
or the location is not accessible, the optional location is
in the return air duct, preferably downstream of the filter.
For higher square footage applications, installing two air
health units, one over the A/C coil in the supply and
one in the return, is ideal for its' cumulative effect.
Practical factors are:
1) The square footage of the heated/conditioned space
2) The size of the duct
Through laboratory testing *, it was found that a
single air health unit reduced
the population of the test bacteria up to 90% with only a
single exposure to the UV light. Other bacteria and molds
will not always have these results with a single pass. Practical
application of air health in HVAC
systems will expose the air in the building to many passes
by the light. This allows for effective reduction of bacteria
and mold with high UV energy requirements for sterilization.
The energy required to kill microorganisms is a product
of UV light's intensity and exposure time. This energy is
measured in micro-watt seconds per square centimeter.
