Why UV-C Light?

Benefits of UV-C Light

  1. Scientifically proven to effectively disinfect & sterilize.
  2. It is a clean & non-chemical approach to disinfection.
  3. It deactivates harmful DNA of pathogens and destroys their ability to multiply & cause disease.
  4. It is a relatively simple & inexpensive method of disinfecting, requiring low maintenance.

Useful Applications of UV-C Light
UV-C is used in many different instances across different industries, such as in the disinfection of drinking water, in food processing, in factories, in laboratories, and in the medical industry.

In February 2020, it was reported that the Chinese government had also used UV light to disinfect banknotes in the wake of the Novel Coronavirus (COVID-19).

Brief Background
Ultraviolet (UV) is a part of the light spectrum, which also includes cosmic rays, gamma rays, x-rays, visible light, infrared and radio waves.

There are three types of UV rays, namely UV-A, UV-B and UV-C, which are classified according to their wavelength ranges. Of the three, UV-A has the longest wavelength and UV-C has the shortest wavelength.

The wavelength of UV-C ranges from 100nm to 280nm.

UV-C is also known as "Germicidal UV" as it demonstrates significant germicidal properties, and is commonly used for disinfection.
