UV-C Germicidal Lamps

UV-C Protection
Apex Duct And Chimney Cleaning is delighted to be able to offer a UV-C germicidal lamp systems designed to protect your family from germs and viruses that are spread by your heating and air conditioning system. These special lamps reduce airborne allergens that can aggravate sinus, nasal, and respiratory problems. They operate continuously -- not just when your furnace or air conditioner's blower motor is running. Ultraviolet germicidal lamps have been used for more than 40 years in hospitals.

Safe And Effective Without Chemicals

According to the American Lung Association, a significant segment of the US population suffers from allergies caused by bio-areosols -- mold spores, bacteria and viruses are examples of bio-aerosols. Your heating and air-conditioning ventilation ducts and filters breed and circulate germs, viruses, and allergy-causing mold spores. These germs include cold viruses, staph, strep, and influenza. Filters and other air cleaning devices are NOT totally effective in removing bio-aerosols and in many cases worsen the problem. The UV-C lamp is professionally installed by your heating and air conditioning contractor. Powered by regular 110-volt household current, it usually requires no additional wiring. As the air passes the lamps, the UV lamps silently destroy or inhibit colony formation of the airborne germs and viruses. The uvc lamp works continuously, 24 hours per day, 365 days per year, yet uses no more power than a 60-watt lamp bulb.

Tested Technology

UV lamps has been used for germicidal purposes for over 40 years. General Electric and Westinghouse Electric tested and utilized the technology. Today germicidal UV lamps are used in hospitals, commercial buildings, and food processing plants. By applying proven UV lamp technology and state-of-the-art design engineering, the UV-C lamp is both safe and effective. The UV-C lamp operates at all times. Many other devices only work when your furnace's blower motor is on. With the UV-C lamp continuous operation, you get optimal lamp life and greater germicidal effectiveness.

It's Fighting Germs All The Time

UV lamps have a cumulative effect on the microbes that pass by the lamps. Those germs and viruses that are not killed during the first pass will sustain some damage and will be eliminated after subsequent passes. In many instances, the damage to the microbe disrupts its ability to reproduce. This is important as a single bacteria can reproduce to hundreds of thousands or even millions of microbes in just 24 hours. Even the most efficient air filters lack complete germicidal effectiveness.


The UV-C lamp is designed to reduce or eliminate the germs that are circulated by your heating/air conditioning system and cause illness and allergies. We have taken proven UV lamp technology and designed effective and safe, state-of-the art products that are unsurpassed. Special consideration has gone into our designs to ensure that no human exposure to the UV lamp is possible when properly installed and maintained by your heating contractor. With our patented cartridge design, the lamps are deactivated when detached from the main housing. The UV-C lamp rids your air of many of those bio-aerosols that can cause illness and allergies. The process is completely natural and environmentally friendly as no chemicals are used.


Ultraviolet light possesses just the right amount of energy to break organic molecular bonds. As micro-organisms pass by the UV rays radiated from the ultraviolet lamp, this bond breakage translates into cellular or genetic damage for micro-organisms, such as germs, viruses, bacteria, fungi (like molds), etc. This resulted in the destruction of the micro-organisms. The same damage occurs to humans, but is limited to the skin and eyes.

UV And Health

According to the (EPA), "(IAQ) has a tremendous impact on people's health". UV stands for Ultra-Violet light. Ultraviolet light represents the frequency of light between 200 nanometers (nm) and 400nm and cannot be seen with the naked eye. Within the UV spectrum lie three distinct bands of light: UV-A, UV-B, and UV-C. Longwave UV light (315nm to 400nm), or UV-A, refers to what we commonly call "black light". UV-B (280nm to 315nm), or midrange UV, causes sunburn. Germicidal UV light (200nm to 280nm), or UV-C, is effective in microbial control. Research has demonstrated that within this UV-C band the most efficient frequency for microbial destruction is between 254nm and 265nm. Germicidal lamps that produce the majority of their output in this range will be the most effective in microbial control/destruction. Germicidal UV light has been proven effective and utilized in numerous applications to improve indoor air quality and therefore indoor environment. The (EPA) states that "indoor air pollution can be much higher than the outdoor environment". In order to fight indoor air pollution people who suffer from asthma or allergies attempt to dust more, keep the windows closed, clean frequently but the allergy or asthma symptoms usually still persist. One reason is the presence of airborne germs, their particles and by products - allergens or asthma triggers in the indoor air. These microbes are considerably big factor in the indoor air pollution.


The airborne germs adversely affect the (IAQ) as they are blown past the furnace or air conditioning filter and circulated throughout the buildings. Ultraviolet light - UVC - is mandatory in hospitals, laboratories, food processing plants, any facility concerned with the (IAQ) as a health factor. UV was incorporated by the U. S. General Services Administration Office of the Chief Architect in The Standard for the Public Buildings. Numerous health studies have shown that germicidal ultraviolet light - UV-C - is very effective against allergies, asthma, mold, mildew, fungi and any DNA based airborne viruses, bacteria and spores. UV light can play a great role in secondary allergy prevention especially where airborne allergens are concerned. It can reduce suffering from allergies. The UV air cleaners help control germs that make asthma worse. Ultraviolet Germicidal Irradiation - UVGI is the use of short UV waves, known as UVC, which has been proven to kill or inactivate tuberculosis in the indoor air. There are two ways that UV lamps are used in (IAQ) control - upper-room and in-duct ultraviolet germicidal irradiation. Many airborne pathogens, such as Anthrax and it's spores, can be removed from the indoor air by the use of germicidal ultraviolet air purifiers. The U.S. government now specifies that UV light should be used in air handling units to improve indoor air quality in government buildings, by controlling airborne and surface microbial growth. The Air Institute of Respiratory Education suggests UV lights be used in buildings for indoor air quality purposes, and states that may be the final line of defense against those diseases that have developed resistance to drugs, such as tuberculosis and others. According to the Aerobiological Engineering Dept. at Penn State University, the ultraviolet component of sunlight is the main reason microbes die in the outdoor air. The die-off rate in the outdoors varies from one pathogen to another, but can be anywhere from a few seconds to a few minutes for a 90 - 99% kill of viruses or contagious bacteria.


The (CDC) recommends UV lights in homeless shelters to prevent the spread of disease, particularly TB (tuberculosis). A study by Air & Waste Management Association found the combination of a (HEPA) filter and germicidal UV lamp reduced bacteria by 80% in a 3072 cubic foot chamber.

UV And Mold

Mold and mold spores adversely affect (IAQ). Health conscious people or those suffering from the presence of mold in their homes need a certain level of knowledge and a lot of effort to clean and keep their environment healthy. Different types of mold - black mold, toxic mold, allergenic mold - are present all the time around us and in the air we breathe. In low levels, molds and mold spores are generally harmless but if their levels increase they can affect people; especially people with allergies, asthma and respiratory conditions or suppressed immune system.


Germicidal UV light (UVC) has been successfully utilized in hospitals and public buildings to inhibit microbial growth, spreading of infections and to increase the indoor air quality. UVC can also help against mold problems by rendering airborne mold particles and mold spores non-viable and even sterilizing surface mold colonies if they are directly irradiated with germicidal UV (UVC) light. Even the dead mold spores and mold particles can be allergenic or toxic so it is strongly recommended to always use germicidal UV light in conjunction with a (HEPA) filtration system.

Do I Still Need An Air Filter?

Yes and no. Stand alone purifiers may or may not have filters. An induct UV light system is designed to be used in addition to a dust filter or electronic air cleaner and the filtration of dust particles will also aid in keeping the bulb(s) of the UV light system clean. However, filters are inefficient at dealing with microscopic bacteria, molds, and viruses and are incapable of preventing mold from growing on a surface. A UV-C Light System contributes significantly to the reduction of the small microbial organisms that pass through filters and into the general air stream. Proper placement of a UV light system above the coil, or a surface area prone to microbial growth aids in reducing the amount of viable microbes on that surface.
