UV-C lights for HVAC systems: A Better Way to Improve Indoor Air Quality.

Thinking about adding Ultraviolet (UV) lights for your HVAC systems in a commercial, industrial or institutional workplace? Looking for a more effective method of cleaning and sanitizing the surfaces of your dental office, hotel room, bar or restaurant? Want to reduce the spreading of germs in your office, school or workout facility by improving indoor air quality? There are several benefits to installing UV / UV-C lights for air conditioning systems in your building.

When properly installed within the HVAC system UV / UV-C radiation lights will eliminate 99.9+% of microorganisms, including bacteria, mold, microbes, viruses and bugs, within the airstream.

In addition to improving indoor air quality, the Ultraviolet light will kill the same microorganisms on the coil providing a clean and more efficient HVAC system. A clean system uses less energy and a corresponding utility savings.

UV / UV-C radiation lights can also be used for surface and equipment sterilization. Portable UV carts and UV wands will sanitize and sterilize any surface. Tables in a restaurant, clothing in retail, bedding in hotels, examination tables in a medical office. A dose of UV will kill any lingering microorganisms and viruses that may exist. UV lights are an incredibly effective tool to create a safe, happy and healthy home and work environment.

What is UV Radiation?

There is scientific research (read study here) that explains in detail how the UVGi wavelength operates within the UV-C spectrum.

Simply put, the UVGi wavelength offers germicidal capabilities.

Do UV lights improve air quality?

Yes, when installed and configured properly, UV lights for HVAC systems are proven to improve air quality (study).

Will an air filtration help too?

Yes. UV is not meant to replace traditional media based air filters. Air filters capture particulate down to a specific size per the filter rating. For example, a HEPA filter captures particulate down to a particle size of 0.3 microns (very small), but bacteria, microbes and viruses are smaller than a HEPA filter can capture.

UV lights then emit a high intensity and the living microorganisms and breakdown their DNA killing them almost instantly. The CDC recommends filters as a media for picking up the larger particles. UV radiation light is ancillary to a media filter and not meant to replace filters, but to be used in conjunction with them in your HVAC system.

What types of UV radiation systems are available?

There are 3 types: air, coil and surface sterilization systems.

Air Sterilization UV Lights

Also known as In-Duct UVC system, works by disinfecting air that is circulating in the ducts using UV-C light. Duct mounting is extremely effective as most ductwork is naturally reflective and will bounce the UV light off the surfaces to improve effectiveness throughout. Once installed, HVAC UV light benefits will be experienced by everyone in your building.

Coil Sterilization is different in the application. It targets areas that are commonly known to have the most issues due to the cool, wet environment. These problematic components are usually filters, condensation pans, and cooling coils. When targeting these specific areas, it allows the UV light for air conditioning systems to focus on tougher to reach areas that tend to have microbial growth resulting in clean air and a clean, more efficient running HVAC system.

Surface Sterilization is targeted at sterilizing surfaces. The surface is not specific, a surface being treated using a wand or cart can be of any construction. Waving a wand over a counter at a restaurant or activating a portable cart in the center of a dental office. The result is the same, the UV light will kill any living microorganism including mold and viruses leaving a clean, sanitized and sterile environment.

UV Light Safety Precautions

A technician must be qualified and take proper precautions when installing the lights. This is to ensure that no occupants are exposed to UV-C light.
