Of all the types of UV light, one in particular can be used to disinfect air and surfaces by killing harmful pathogens.

UV light is crucial to life as we know it. UV light, which is most commonly known as ultraviolet radiation, is a fundamental part of our survival and existence on Earth. UV rays are responsible for many things, from helping plants grow to sterilization of bacteria-covered surfaces. At Farlite Solutions, we have developed proprietary technology focused on using UV light to disinfect the air inside buildings. Learn more about this incredible technology now.

Three Types of UV Light

There is a common misconception that only one type of UV light exists. Actually, there are three different types of UV light. The three UV light categories are UV-A, UV-B, and UV-C. Each category of UV has a unique role in the world around us, determined by its wavelengths.

UV-A is the most common type, falling between 315 and 400 nanometers. It is primarily responsible for skin aging and sun tans. Additionally, UV-A lamps are the most commonly found in tanning beds. UV-A rays make up 95% of the UV rays that reach the ground. The effects of UV-A rays can appear on your skin very rapidly. 

Next, UV-B rays comprise the other 5% of the UV rays that penetrate the earth’s ground. UV-B rays fall into the range of 280 to 315 nanometers. UV-B rays are responsible for the mutation of our DNA. The effects of this can be various types of skin cancer, another reason to be very wary of your own and your loved one’s sunscreen regimen. 

Lastly, UV-C rays do not even touch the earth’s surface; they are absorbed into its ozone. UV-C rays would cause severe damage to our skin, eyes, etc. UV-C has the most energy levels out of the three, so it is utilized in artificial forms. UV-C can be seen in welding torches, mercury lamps, and, most importantly, germicidal lamps. UV-C rays are arguably the most critical kind, especially regarding the disinfectant component. 

Using UV-C Light to Safely Disinfect Indoor Air

To harness the power of UV-C light for disinfecting indoor air effectively and safely, it is crucial to position UV-C sources strategically within an enclosed space. This involves installing UV-C light fixtures near the ceiling, far from human height, to prevent direct exposure, which can be harmful. 

By ensuring the lights are placed well above the occupied zone, the UV-C rays remain confined to the upper air regions, where pathogen-laden air can be disinfected as it naturally rises due to convection. With proper shielding and fixture design, these systems can operate continuously in occupied spaces, purifying the air without risk to occupants, thus combining safety with continuous disinfection.
