Over the years’ many professionals have advanced UV technology’s applications and opportunities, however this has meant that along the way a few myths have been carried through. Ensure you get your facts straight about UV disinfection with UV specialists, UVO3.

What are the myths?

  • UV disinfection equipment is not energy efficient – UV disinfection requires a large amount of energy, it has low electrical efficiencies and therefore makes UV disinfection a more expensive disinfection method compared to alternatives.
  • UV lamps are difficult to be disposed of due to the mercury contained inside UV lamps being hazardous to end users and the environment.
  • There is a risk to users of the UV lamp as potential exposure to UV-C radiation, which also releases emissions that cause algal growth.
  • UV disinfection lamps are always burning out and therefore require replacement, along with needing a significant amount of time to maintain and clean your UV disinfection system.

  • UV disinfection equipment is not cost effective for virus inactivation and residual.
  • Microorganisms can re-activate after undergoing UV disinfection.
