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.
