What Is Ultraviolet Light?
In order to understand the various functions of ultraviolet (UVC) light and how it is used for air sanitization, it’s important to understand what exactly UVC light is. Ultraviolet light consists of short wavelengths that are invisible to the human eye. The sun naturally produces three kinds of light: UVA, UVB, and UVC. The first two (UVA and UVB) have long wavelengths and enter the atmosphere in varying intensities. They are the reason we wear sunscreen and sunglasses to prevent skin and eye damage.
On the other hand, UVC light has short wavelengths and, for that reason, is almost entirely absorbed back into the earth’s ozone layer. Despite being a powerful light, it is one that people are generally less familiar with.
In the 19th century, scientists discovered UVC light’s ability to kill up to 99.9% of bacteria and viruses in both water and air. Since then, UVC light has been widely utilized as an effective air sanitization method.

How Can Ultraviolet Light Kill Germs?
UVC light has the unique ability to penetrate the thin walls of microorganisms and disrupt their DNA structure. As a result, the microorganism is either killed or rendered inactive, meaning it is no longer capable of reproducing. This is what happens to germ, virus, and bacterial cells that come into contact with UVC light.
It’s important to note, UVC light has a very limited range and does not pose a health risk for human cells, as it can’t break through the outer dead-cell layer of human skin or the tear layer in our eyes. Viruses and bacteria are much smaller than human cells, allowing UVC light to easily reach their DNA and alter their structure.

What Are the Beneficial Uses of Germicidal Ultraviolet in Your Cincinnati-Area Home?
UVC air sanitization has become more accessible and widespread, preventing the transmission of deadly germs and viruses all across the world. It can now be implemented in your home through your HVAC system, using an application known as in-duct UVGI. This method allows for air to be disinfected as it passes through your heating and cooling system, before it gets recirculated or exhausted. Using UVC light in HVAC systems greatly improves indoor air quality, as well as energy savings.
There is a variety of indoor air quality products available to help kill or sterilize airborne bacteria and viruses. With the increasing uncertainties surrounding the novel coronavirus and its potential for global impact, there is no time like the present to explore UVC air disinfection and the indoor air quality options available to you!
