Ultraviolet (UV) is one of the more effective methods to reduce and control airborne pathogens. For this reason ultraviolet purifiers are commonly used in hospitals. As contaminated air is passed through intense ultraviolet light, bacteria, viruses and some organic compounds are destroyed. In short, the ultraviolet light damages the DNA of microorganisms and renders them harmless and unable to reproduce. Ultraviolet light is used in much the same way for water purification systems. Because viruses are too small to be trapped by HEPA filters, ultraviolet light is one of the only ways to eliminate airborne viruses. A basic characteristic of UV lamps is that the larger the lamp, the greater the output of ultraviolet germicidal irradiation (UVGI). But larger or longer UV lamps that create ozone can also produce too much ozone. To solve this problem, RGF developed a proprietary broad spectrum, high efficiency UV bulb (HE/UVTM) to work with their hydrated quad-metallic target and PPC-UV bulb coating. The target acts as a catalyst for a hydroxyl radical reaction of the broad spectrum 100-300 nm HE/UVTM energy with water vapor on the hydrated target. The results are hydro peroxides, super oxide ions, passive negative ions hydroxides and ozonide ions. The cell creates a very aggressive advanced oxidation atmosphere that has the ability to reduce airborne bacteria, mold and viruses up to 99% also odors and VOC's by up to 97%. A proprietary protective poly shield (RGF PPS) shields the bulb from temperature fluctuations and breakage that could release mercury, which is a problem for all UV bulbs.

Scientists have divided the ultraviolet part of the spectrum into three regions: the near ultraviolet, the far ultraviolet, and the extreme ultraviolet. The three regions are distinguished by how energetic the ultraviolet radiation is, and by the "wavelength" of the ultraviolet light, which is related to energy. High Efficient Particulate Air (HEPA) filter guarantees that the filter will capture airborne particles down to 0.3 microns in size, 99.97% of the time. (Particles smaller than 0.3 microns are still trapped by HEPA filters but effectiveness is reduced to less than 99.97%.)
