UV Systems in Tampa, Brandon, St Petersburg, FL, and Surrounding Areas
According to the EPA, airborne flu viruses can be captured and sterilized with a combination of high-efficiency filters and Ultraviolet C (UVC) Light
•Adding filters and Ultraviolet C (UVC) together in successive layers can provide a necessary resistance to prevent the distribution of airborne viruses.
•A MERV10 filter alone captures only 10% of the flu virus whereas adding an ultraviolet lamp triples the total single pass capture/sterilize rate to 35%.
What is Ultraviolet Light and how does it work?
The C wavelength of the UV spectrum targets the DNA of microorganisms, destroying their cells or making replication impossible. Directed at a cooling coil or drain pan, Ultraviolet C energy destroys surface bacteria, fungi, debris, etc… that grows in the presence of moisture. Ultraviolet C also destroys airborne viruses and bacteria that circulate through an HVAC system. Ultraviolet C (UVC) light was artificially created in the 1880’s and later commercially used to kill waterborne viruses and bacteria in 1909. By the 1930’s surgeons were using Ultraviolet C (UVC) light in operating rooms to reduce airborne bacterial and viral infections.
Since the 1930s
Ultraviolet (UV) lights have been used since the 1930s in commercial and industrial applications including, but not limited to, sanitizing meats and vegetables, medical applications, air treatment, and water treatment. Residentially they started to emerge as in-duct air purifiers in the early 1990’s. Ultraviolet lights are a proven technology, yet they must have the right wavelength and have enough power for a surface kill of biological growth, as well as airborne control of micro-organisms and germs.
To make sure you are getting what you paid for when deciding on which Ultraviolet light to have installed into your HVAC system the light must have an Ultraviolet C (UVC) germicidal wavelength lamp and enough microwatts of power to get the job done. Ultraviolet lights below 55 microwatts of power have little effect for this application and 70 – 180 microwatts is recommended.

By controlling surface and airborne microbes, UVC can be beneficial in many ways, including Indoor Air Quality (IAQ) control and energy savings:
IAQ Control – UVC improves air quality by preventing the spread of airborne viruses and reducing the allergy and asthma symptoms triggered by biofilm/mold. It creates safer and more comfortable indoor environments, resulting in a happier and healthier home for you and your family.
Energy Savings – Studies show that even a very thin (.024″) layer of biofilm buildup on a coil increases energy consumption by 21.5%. UVC provides continuous cleaning of coils to eliminate biofilm more effectively than conventional cleaning methods. Field data from UVC commercial and healthcare installations has shown resulting HVAC energy savings ranging from 10% to 28%.
