UV Light Combats the Coronavirus
by Connie | April 2024

Innovative technologies play a significant role in developing effective strategies to halt the spread of disease.

The COVID-19 pandemic highlighted the importance of innovative technologies, including ultraviolet (UV) disinfection, in stopping the rapid and widespread outbreak of illness.

UV light, specifically UVC light, is known for its germicidal properties and its application in disinfection processes. Since the pandemic, it has gained increased attention for its ability for chemical free contamination control in healthcare facilities, public spaces, and transportation.

Ultraviolet Technology: Contamination Disruptor

Infections are caused by various pathogens, including bacteria, viruses, protozoa, or fungi. When provided with the right conditions—nutrients, moisture, and favorable temperatures—pathogenic bacteria can undergo exponential growth; potentially doubling in number in as little as 20 minutes.

UV light combats a wide spectrum of pathogens, highlighting its value as a comprehensive sanitization solution. Different wavelengths of UV light disrupt the DNA or RNA of microorganisms, preventing them from reproducing and causing harm.

What Is UVC?

UV light technology is a spectrum of electromagnetic radiation emitted, in controlled environments, by specialized lamps. There are three main types of UV light—UVA, UVB, and UVC. Among these, UVC light, with wavelengths ranging from 200 to 280 nanometres, stands out for its potent germicidal properties.

When used correctly it has demonstrated remarkable efficacy in swiftly inactivating the coronavirus 2 (SARS-CoV-2).

The energy from UVC wavelengths is absorbed by the genetic material inside viruses and microbes, leading to their rapid destruction and rendering them inactive.

UVC light can eliminate up to 99.99% of harmful bacteria, viruses, molds, fungi, and spores that are often found both on surfaces and in air and water. It stands to reason, then, UVC light will have the same effect on other viruses, including the influenza virus (the flu) and rhinovirus (the common cold).


It’s essential to note that UVC is distinct from UVA sunlight exposure and UVB medical and tanning beds.

Using UVC For Contamination Minimization

Minimizing the risk of COVID-19 transmission through contaminated surfaces, air and water is crucial, as the virus can persist for an extended period – surviving on plastic and steel surfaces for up to three days. This highlights the importance of thorough sanitization practices.

While traditional cleaning methods are effective to a certain extent, they may not eliminate all residual contamination. This is where UVC (ultraviolet C) light is particularly valuable.

UVC Applications

UVC light has been used extensively since the 1800’s to disinfect wastewater, drinking water, air, surfaces and pharmaceutical products against a range of human pathogens.

A UVC lamp can be used to purify water, decontaminate surfaces in vacant hospital rooms, and sterilize large vehicles such as buses.

Airborne viruses and microbes are targeted by strategically placed UVC lights and fans. Fan-assisted circulation ensures that all air is exposed to the UVC lights, thereby neutralizing any germs suspended in the air.

The use of UVC lights in air ducts is effective in preventing the spread of viruses and germs between rooms that are interconnected.
