Ultraviolet (UV) light is a form of energy known as electromagnetic radiation. It comes from the sun and man-made sources. UV light is not visible to the human eye because it has a wavelength shorter than the light we can see. Ultraviolet germicidal irradiation is a method that uses a type of UV light — UVC light — to kill a range of germs.

What Is UV Light?
Within the visible light spectrum, violet has the shortest wavelength of any color. Any light with a shorter wavelength than violet is called ultraviolet. There are three types of UV light:
- Ultraviolet A (UVA) light: UVA light is also known as blacklight, and it’s the type of UV light with the longest wavelength. Some birds and insects can see UVA light.
- Ultraviolet B (UVB) light: UVB light is the type that causes sunburns. Most of this light is absorbed by the ozone in the Earth’s atmosphere.
- Ultraviolet C (UVC) light: UVC light has the shortest wavelength of the UV light types and high energy. This form of light is also called germicidal and is used to disinfect air, water, food and laboratory equipment. The Earth’s atmosphere completely absorbs UVC rays, so they never make it to the surface.
Does UV Light Kill Viruses?
While all forms of UV light can inactivate various microorganisms on some level, UVC light is the most effective at killing germs, including viruses like the one that causes COVID–19. That’s why home or business owners may consider installing UV germicidal lights in their heating, ventilation and air conditioning (HVAC) systems. These lights kill virus particles that would otherwise pass through air filters.
How Does UV Light Work?
UV germicidal lights inactivate viruses by damaging their genetic material and preventing them from replication. A virus needs its DNA or RNA to infect other living cells. Without this material, it cannot invade a human cell and make copies of itself. UVC light has been used for decades to destroy viruses and disinfect surfaces, air and water.
Does UV Light Kill the Coronavirus?
Although there are currently no studies that prove UV germicidal lights can kill the coronavirus, scientists say it’s likely. UVC is known to destroy viruses related to SARS–CoV–2, or the virus that causes COVID–19. This also includes the virus that causes MERS.
Does UV Light Kill Other Germs?
UV germicidal lights can also destroy bacteria and mold. Although tiny particles like viruses and bacteria are more vulnerable to UVC light than large ones, germicidal lamps still have the power to kill mold spores. UVC light is especially effective when it’s combined with high–efficiency air filtration.
How Does HVAC UV Light Installation Work?
UV germicidal lights can be installed inside your HVAC system. These lights can help clean the air inside your home by killing harmful microorganisms such as mold spores, bacteria and viruses. At OASIS Heating, A/C & Refrigeration, Inc., we can install a UV germicidal light inside your HVAC ductwork or air handler, which will keep these organisms from spreading throughout your home.
Even if you have efficient air filters installed in your HVAC system — whether it is an electronic or mechanical air filter — they are not designed to kill bacteria, viruses and other microorganisms. Filters can provide ultimate protection when installed alongside a UV germicidal light.
We can help you select the right combination to improve your indoor air quality and potentially reduce exposure to viruses, bacteria and allergens. We take the whole–home approach, so our indoor air quality experts may suggest other ways to eliminate pollutants.
