According to the American Medical Association, 50% of all illness is caused or aggravated by polluted indoor air.
The air in today homes & buildings contain contaminants such as bacteria, virus, mold, fungi & spores that contribute to many illness:
Asthma, Fatigue, Frequent cold & flu, Sore throat Headaches, Runny nose, Dizziness Respiratory allergies, Nausea, etc
The US Government required UV Air devices to be installed in Government building as protection against Airborne Germs, Bacteria, Virus and Mold.
Because UV (Ultraviolet) light is one of the more effective methods to reduce and control Airborne pathogens.
For this reason, UV air devices are commonly used in hospitals.
Due to viruses are too small to be trapped by HEPA filters, UV light is one of the only ways to eliminate airborne viruses.
As an airborne micro-organism passes over the UV light, the UV light penetrates the organism’s membrane and alters its genetic material (DNA).
With altered DNA, the micro-organism will no longer be able to reproduce, rendering it biologically dead and therefore harmless.
Due to the short life span of most micro-organisms, once they lose the ability to reproduce, the population diminishes rapidly and drastically.
Since the UV light is only directed inside the unit, there are no potential harmful side effects.

G9 Germ Killer uses this approach. It attacks the sources of pollution directly, thus removing the source of odor and bacteria problems, giving the room a pleasant, refreshing and clean air environment.

The G9 Gem Killer is mounted at a height of 6 to 8 feet on the wall.
Air will be sucked into from the sides in to the unit, along the UVC Lamp in parallel.
This creates a zone of UVC light at the top portion of the room, above the occupants.
Natural convection, air from HVAC vents and human movement cause the air in the room to circulate.
As air enters the disinfection zone, it is exposed to the UVC light rays.
This destroys viruses and bacteria in the air, including MDROs.
G9 Gem Killer contains one or more germicidal ultraviolet lamps.
The UVC Lamps are short-wave low-pressure tubes that produce ultraviolet wavelengths lethal to microorganisms.
Approximately 95% of the ultraviolet energy emitted from the UVC Lamps is at 254 nanometers, the region of germicidal effectiveness most destructive to bacteria, mold and virus.
Therefore, the air that passes through the chamber is exposed to the Germicidal UVC Lamp and the genetic material of the microorganism is deactivated, preventing reproduction and rendering them harmless.
