Adding UV to your heating, ventilation and air conditioning system can reduce allergy symptoms
60,000,000 people in the United States are affected by allergies, and mold is one of the 5 most common allergens. The dark, cool and moist surfaces that typically exist in HVAC systems are very favorable places for mold growth. The spores released from the growth are distributed throughout the structure. Applying UV light in these vulnerable areas can make a huge difference in the spore counts in the air. In regions where the air is typically drier and mold growth is less of a problem, UV applied in the recirculating airstream passing through an HVAC system can make a significant reduction in the mold spore counts in indoor air. By reducing the density of mold spores, the indoor air quality is enhanced and allergy symptoms reduced.
UV Kills Germs!
Fresh outside air is healthy to breathe in part because natural UV from the sun controls the level of airborne microorganisms. Ultravation® brings UV indoors to help control microorganisms in indoor air. With a UV system installed in your HVAC system, the numbers of airborne bacteria and viruses that cause colds and other illnesses will be reduced as air is circulated through the system. With most people spending as much as 90% of their time indoors, optimizing indoor air quality becomes increasingly important. Today's advanced building techniques are another factor to consider when evaluating indoor air quality. To increase heating and cooling efficiency, and to add to indoor comfort, homes and commercial buildings are more airtight than ever. While efficiency and comfort goals may be achieved, an unintended effect is that with less outdoor air "leaking" into the indoor space, airborne organisms and other contaminants can accumulate. The HVAC system now has an increased role in maintaining indoor air quality -- adding UV disinfection along with filtration and other enhancements helps it fulfill that role.
UV Controls Mold!
That smell when the air conditioner turns on -- especially after it has been off for a while. What is it? Chances are it's MOLD, and those mold spores spread around, landing everywhere in the house. Or if mold is growing in a damp place elsewhere in the house, the air conditioner helps distribute the spores as the air is recirculated. UV can play an important -- if not vital -- role in controlling home damaging mold. As insurance companies raise rates and even exclude mold damage from their coverage, UV can be a big help -- consult your HVAC contractor.
How a UV system pays for itself: It saves energy!
A UV system uses about the same amount of electricity as a standard light bulb. Yet it can help your HVAC system increase its efficiency, so you may use less power overall. When mold becomes established on cooling elements, it begins to insulate it from the passing air. This makes the heat transfer from the air to the elements more difficult. When this happens the HVAC system begins to run a little longer and then cycles more often to accomplish the same temperature setting. This obviously uses more energy and in addition, increases wear and tear on the system. Of course we recommend quality filtration to keep the elements as well as the UV lamps free of dust, then the UV will keep the mold away, and help to optimize efficiency.

Indoor air as Healthy as Outdoors
The problems associated with maintaining indoor air quality (IAQ) have become more apparent and more serious in recent years. It is now well established that in homes or structures where groups of people congregate, and where the air is continually re-circulated, indoor air pollution steadily increases. As building construction techniques have improved creating tighter interior spaces, the role of the heating and ventilation system has become increasingly important. No longer is it enough to simply provide temperature and humidity controlled air. High quality, healthful air is now the goal. Ultravation® products are designed to work with central heating and air conditioning to restore indoor air quality to the maximum possible level. Ultravation® UV systems remove mold, bacteria and allergens; Ultravation® Progressive filtration removes particles and Ultravation® Photronic uses a photocatalytic process to obliterate unpleasant odors— all of which work together to make indoor air much more healthful, free of contaminants. In short our mission is to create . . . Indoor air as healthy as the great outdoors!

Electromagnetic Spectrum

The ultraviolet region of the electromagnetic spectrum has a frequency just below visable light.
How UV Lights affect DNA
 |
Ultraviolet light is nature’s way of controlling microorganisms. Outdoors, germs are naturally regulated by the ultraviolet light from the sun.
How the Ultravation® air disinfection system reduces microorganisms indoors
The UME-Series equipment produces ultraviolet light at the specific wavelength of 254nm (nanometers). At this wavelength the UV light is most effective at inactivation. As an airborne microorganism passes through your heating and/or air conditioning system, the UV light from a UME-Series unit penetrates the organism’s membrane and alters its genetic material (DNA). With altered DNA, the microorganism will no longer be able to reproduce—making it effectively harmless. Further, without the ability to reproduce, and due to the short lifespan of most microorganisims, the population of them in the air diminishes rapidly and dramatically.

Don’t just remove harmful airborne contaminants, destroy them.
Your home’s central heating and cooling system presents the perfect breeding ground for mold, mildew, bacteria and fungi and the odors associated with them. The Aprilaire Whole-Home UV Germicidal Lamp kills these harmful contaminants that wreak havoc on your family’s indoor Air Quality.
The U.S. Government mandates that UV germicidal lamps be installed above air-conditioning coils in all new government buildings.
"...for innumerable molds, fungi, and bacteria, home sweet home is a series of drain pans in the ventilation system. If they aren’t kept clean, the biological agents can proliferate and then travel through the building on air currents.”
How Does It Work?
The air conditioning or heat pump coil that is part of your heating, ventilating, and air conditioning (HVAC) system is designed to cool the air passing through it, thus generating comfortable air for your home. During this process dehumidification also occurs as water condenses from the air stream onto the cooling coil. This water, referred to as condensate, drains away from the air conditioning coil into the drain pan and through the drain connection on the side of your furnace/air handler.
Extended operation of an air conditioning system and the associated moisture on the air conditioning coil is a breeding ground for mold and bacteria. The technology incorporated in an Aprilaire UV Germicidal Lamp uses UVC spectrum light to kill mold and bacteria growing on the coil by breaking down their DNA. This technology has been used for over 60 years to kill microorganisms in water purification and food processing industries, government buildings, hospital operating rooms and more.
“Common harmful molds can be found in air conditioning systems including Aspergillus, Penicillium and Cladosporium.”
The Aprilaire UV Germicidal Lamps work automatically to help protect your family’s health and your heating and cooling equipment 24/7/365. Once installed as part of your home’s central heating and cooling system, the Aprilaire Whole-House UV Germicidal Lamp works non-stop to keep your system free of harmful mold and mildew growth.
Why Do I Need It?
The UV Germicidal Lamp helps reduce the risk of allergic reactions and illnesses caused by biological growth on the air conditioning or heat pump coil and will eliminate the foul odors associated with such growth on the coil. In addition by eliminating this growth, your air conditioner will run at peak performance, last longer and use less energy.
“Keeping coils sanitary—through cleaning and the application of chemicals and/or UV lights—is part of a system-wide approach, which can prevent spores from amplifying in the heating and air conditioning system.”
Core Benefits
Every Aprilaire product provides important key benefits for your family and home.
