Researchers at Temple and George Mason Universities demonstrated that 10-20 seconds exposure of human coronavirus OC-43, Zika Virus (ZIKV), and HTLV1 viral stocks to Anthem One UV-C light completely eliminates viral infectivity in cells in culture. Anthem One UV-C light has been examined for its capability for eradication of human pathogenic viral agents including members of Coronaviruses, Flaviviruses, and Retroviruses.

Germicidal ultraviolet (UV-C) light inactivates the DNA of many bacteria, virus, and fungus — preventing their ability to multiply. Specifically, UV-C energy causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA/RNA. The formation of such bonds prevents the DNA/RNA from being unzipped for replication, and the organism is unable to reproduce. Multiple studies prove frequencies near 265nm is the most easily absorbed by DNA.

UV-C light destroys viruses, bacteria, protozoa, fungi, yeasts and algae.  Interestingly, UV-C does not penetrate proteins such as the keratin in our skin, nails & hair or the elastin in our lungs. GDW Fulfillment systems are designed with safety in mind. We recommend UV-C coated protective glasses, long sleeved shirt, and gloves if using the hand held Anthem One Cube. Our ceiling Air filtration systems are completely enclosed and can be used in an occupied room without being exposed to UV-C light.  Our high touch adapt unit automatically shuts off when detecting human action near the unit. No additional caution measures are needed. If you are exposed to direct germicidal light, it can burn the top surface of your skin. If your eyes are exposed, your eyes can feel dry or gritty. At no time do germicidal lamps cause any permanent damage.

The average bacteria will be inactivated in seconds or minutes depending on three important aspects of ultraviolet light. This is important to understand in order to calculate the pathogen kill time for your space. One aspect is the intensity or killing power of the source of UV-C, the second is distance from that source, and thirdly is time exposed to the source. Now let's get nerdy. The inverse square law applies to germicidal ultraviolet energy as it does to visible light: the intensity decreases as the distance from the lamps increases.  For example, a high intensity output will eliminate pathogens faster than a low intensity output covering the same distance. However, add in time. The low intensity UV-C light source can destroy as many pathogens as the high intensity light given enough time exposure. Let's consider distance. The light source intensity or killing power decreases with longer distances. Does that mean the light is not going to disinfect the complete distance of a room? No. The further the distance from the UV-C light source, longer exposure time is needed to eliminate pathogens.

5 Benefits of UV-C Disinfection



Clinically proven to eliminate bacteria, viruses, and fungi up to 99.9%. The recent COVID-19 pandemic has lead to further innovation in an already advanced technology, as well as scholastic research validating its effectiveness. 



No more budgeting for gallons of chemical disinfectant or commercial cleaning services. Our easy-to-use devices lower the maintenance and operation cost required to disinfect and sanitize everything from countertops to electronic devices.



Not only do we provide necessary equipment and installation services, but above all our goal is to make the process of disinfecting safe for everyone involved. We have PPE, certification courses, and more to ensure peace-of-mind as you transition to UV-C.


Eco Friendly

Choosing UV-C is choosing to take one more step to a greener future. The majority of household and commercial cleaning products contain harsh chemicals – e.g. bleach, ammonia, boric acid – or aerosol propellants accelerating climate change.



Effective enough to disinfect food preparation or medical surfaces, and innocuous enough to use in classrooms and homes.
