How does UVC Light for mould removal work?

Updated: Dec 1, 2021

UVC light is a part of the electromagnetic spectrum, which is the spectrum of waves that include visible light, infrared, radio, and more. Over 140 years ago, Arthur Downes and Thomas Blunt discovered that sunlight seemed to have antibacterial properties. They determined that shorter wavelengths of the spectrum were more effective at killing bacteria and other organisms.


UV-C, UV-A, and UV-B light all fall under the umbrella of ultraviolet light, a high-energy variant of visible light that has significant germicidal and anti-bacterial effects. By utilising UV-C light, we are able to destroy more than 99.99% of all pathogens - both in air and on surfaces - within seconds, all without adding chemicals, and their potential harmful side effects.


Not to mention, it's inexpensive, highly efficient, and incredibly reliable!


The cell nucleus of micro-organsims and other pathogens, like bacteria and viruses, contain thymine, a building block of DNA. This element absorbs the UV-C light to such an extent that the cells are no longer capable of multiplying and surviving. All bacteria and viruses tested to date - including other coronaviruses - respond to UV-C Disinfection. Some organisms are more susceptible to UVC disinfection than others, but all tested so far respond to appropriate doses.

HOW DOES UV LIGHT KILL GERMS?


  • UV-C penetrates the cell wall of the microorganisms

  • The high energy photons of the UV-C are absorbed by the cell proteins and DNA/RNA

  • UV-C damages the protein structure causing metabolic disruption

  • DNA/RNA is chemically altered so organisms can no longer replicate

  • Because microorganisms are now unable to metabolize or replicate, the UV-C light has effectively and safely sanitized the UV-C workspace area.

UVC LIGHT FOR Sanitisation

Light is comprised of different wavelengths, each with their own unique properties. The germicidal properties of ultraviolet (UV) light, part of the non-visible spectrum, can be harnessed to effectively sanitize the air, water and surfaces. At the appropriate wavelength and fluence (dose), exposure to ultraviolet light modifies or destroys the genetic material (DNA and RNA) in all viruses, bacteria and mold, preventing replication. Xspor Ultra's air and surface sanitizing products employ various combinations of UV light and filtration to inactivate pathogens, including Far UV-C (200-230nm) which is safe for human exposure, UV-C (231-280nm), with some products also utilizing UVB and UV-A (365nm).

BROAD SPECTRUM OF LIGHT FOR OPTIMUM EFFECT


The innovative products at Xspor Ultra bring a significant breakthrough in germicidal protection for our world- safely managed disinfection on demand. The new generation of light sanitisation solutions has a range of products which utilise different segments of this powerful, broad-spectrum light, including germicidal UVC (231- 280nm) Far-UVC germicidal (200-230nm) which is known to be safe for human exposure, UVB and anti-bacterial UVA to optimise the germ-killing efficiency of the products specified.

UV-C is most traditionally referred to as germicidal UV with UVC irradiation having the ability to kill pathogens and mircro-organisms such as bacteria, viruses, E-Coli, influenza streins, dustmites, mould and fungus.


UV-A and UV-B light causes oxidation of proteins and lipids causing cell death. UVB penetrates and damages the outermost layers of your skin. Overexposure causes suntan/tanning, sunburn and, in severe cases, blistering.
