The Top 3 Reasons Why UV-C Light Is An Excellent Disinfection Technology

Ultraviolet C, or UV-C light, is considered a powerful tool for disinfection. But why is this the case? Here are the top 3 reasons why UV-C light is an excellent disinfection technology.

1. UV-C light has a high disinfection efficacy rate 

UVD Robots are a series of mobile disinfection robots that use UV-C light - a type of ultraviolet light associated with high rates of disinfection against several microorganisms. 

UV-C light has an especially high rate of efficacy when at wavelengths of 254 nanometers (nm). 254nm UV-C light has, in laboratory conditions, been associated with the reduction of:  

• Staphylococcus aureus,
• Clostridioides difficile, and
• Escherichia coli
  
  at greater than 3-log to greater than 6-log rates of efficacy, representing reduction rates of greater than 99.9% to greater than 99.9999%.¹
  
  

2. UV-C light can reach all areas of a room - especially when mobile

UV-C light can be emitted from different devices in a process called Ultraviolet Germicidal Irradiation, or UVGI. For this, mobile technologies have been developed for UVGI.

Technologies such as UVD Robots have been developed to face obstacle-oriented issues such as distance and shadowing. As self-driving mobile robots, UVD Robots can operate autonomously, delivering UV-C light to disinfect rooms, in many cases, within 10 minutes.²

3. UV-C light works on an intracellular level

UV-C light is effective against microorganisms because it deactivates the DNA and RNA within their cell structures by disrupting the DNA and RNA repair process.³

UVD Robots use 254nm UV-C light, which similarly affects microorganisms at an intracellular level. In this way, UVD Robots can be combined with traditional cleaning and disinfection methods to deliver the most of UV-C light’s excellent disinfection properties.
