Q: Does UV really work? A. UV has been proven under numerous studies for its ability to destroy the DNA of germs: viruses, mold, spores, fungi, and bacteria. It works at different levels depending on what one wants to accomplish.
Example 1: In the commercial world, i.e. hospitals, clean rooms and food processing plants, the objective would be to have instantaneous kill. Therefore, UV lights would blanket the air passage system and the airflow directed over and between lamps, which provide for maximum kill of air pollutants. This process is expensive.
Example 2: In residential applications, the objective is to create a cost effective and continuous method of cleaning the air. The kill rate of air pollutants is a function of space, time and the intensity of UV. Because UV has been proven to work in a cumulative manner, the polluted air is cleaned over time and subsequent passages over the UV lamp - the same way like we wash our hands more than once a day to periodically get rid of germs. Germs are constantly growing in our indoor environment and pollute the air we breathe. UV technology gives us the opportunity to clean the indoor air continuously in a cost effective manner.
Q: Has UV technology been tested? A. Yes. Westinghouse Electric, General Electric, Penn State University and Harvard School of Public Health conducted laboratory tests on the effectiveness of UV light on microorganisms. UV light has also been used in wastewater plants and commercial settings for over 60 years. Recent studies are proving the UV technology effective against biological terrorist attacks and for reducing sickness due to airborne pollutants.
Q. Have indoor airborne contaminates increased? A. Yes! We have changed our homes in such a way to accelerate growth of microorganisms. Self defrost refrigerators, air conditioned and energy tight homes, are a few examples for environments that provide breeding grounds for accelerated growth of mold and bacteria that mix with the air we breathe. Airborne house dust is a by-product of our living indoors, from dead skin, to hair, to paint flakes, to dust mite feces. Since we now live indoors up to 95% of the time, more house dust is produced.
Q. Is UVC similar to ozone? A. No! Ozone is a chemical; UVC is electromagnetic energy, or rays. Ozone, as a chemical, can mix with the air and travel by air currents into the breathable air space. Ozone oxidizes or alters the chemical structure of material it contacts. UVC does not mix with the air, but travels by wave energy. To be effective, that energy has to be in the line of sight. Further, the UVC energy degrades within a few feet of the light source.
Q. Do microorganisms have to be within sight of the UVC to be killed? A. Yes, if UVC rays are being used. To be killed by UVC, germs must be irradiated directly. Germs can be affected by reflected UVC, but it takes longer and must be closer to the reflected light source. Few materials, (primarily polished aluminum and magnesium oxide) effectively reflect UVC. The common mirror will not.
Q. Where in our home should we place UVC? A. Standing indoor air has such volume and is so dispersed throughout the rooms of the home, it becomes impossible to effectively clean it. But there is one place in most homes where 100% of the air can be conditioned every 12 to 15 minutes. That area is in an operating central heating and cooling airflow system (HVAC). So if we need to clean and purify the breathable air, it should be done within the HVAC unit. It is within this system that the UVC lamp should be placed to take advantage of the one point where the total air can be cleaned.
Q: What kind of germs are affected?
A. UVDI Air Cleaner is extremely effective against virtually any airborne microbes including rhinoviruses (colds), influenza, bacteria, mold, mold spores and viruses.
Q: Is UV light harmful to people?
A. Prolonged, direct exposure to UV light is harmful to all living organisms, including people. However, the UVDI UV system has been designed with safety in mind. There is minimum exposure to people. This provides for safe operation and maintenance.
Q: Why not use ozone generating air cleaners?
A. The EPA and American Lung Association are strongly against the use of ozone indoors. It has been determined that ozone is corrosive to lung tissue. In addition, ozone is known to be very corrosive to certain materials and can damage your HVAC system.
Q: Don’t air filters eliminate germs?
A. Air filters do trap microbes; but even the most sophisticated air filters do not contain 100% of the germs. Microorganisms not trapped will reproduce very quickly and contaminate the indoor environment. In some cases the air filters become breeding grounds for new colonies of germs.
