FDA talks about HVAC UVC Lights for Coronavirus inactivation

FDA talks about HVAC UVC Lights for Coronavirus inactivation

Ultraviolet lighting products are under a harsh spotlight, because of coronavirus pandemic. As you may know UV Light can help disinfect surfaces and air, but this topic comes with huge covid caveats theese days. Many businesses are turning to UV light for its ability to destroy germs and other pathogens. But can UVC lamps inactivate the SARS-CoV-2 coronavirus? The FDA is providing answers to consumers’ questions about the use of UV Lights and Lamps for disinfection during the COVID-19 pandemic. You can read about it here >

UV-C has a proven track record of neutralizing a range of microorganisms. It is now known that Far-UVC light (222 nm) efficiently and safely inactivates airborne human coronaviruses.

The importance of a healthy workplace in now a top priority as businesses seek to operate safely during the COVID-19 pandemic. Given the current outbreak of Coronavirus Disease 2019 (COVID-19) disease caused by the novel coronavirus SARS-CoV-2, consumers may be interested in purchasing HVAC ultraviolet-C (UVC) lights & lamps to disinfect air and surfaces in the homes, businesses or other similar spaces.

For safety reasons HVAC UV lights can only be installed by trained personnel.
UV light can be effective at inactivating viruses like the coronavirus and influenza, but only when properly implemented!


How to use Ultraviolet light to fight COVID-19?

Ultraviolet light comes in 3 spectra ranges:

Light Spectrum - UV Light Range
  • UV-A (400-315 nm)
  • UV-B (315-280 nm)
  • UV-C (280-100 nm)

UV-C is what you need to really kill pathogens like COVID-19, influenza, or TB. The consensus is that 254-nm is the ideal wavelength, although there’s on-going research looking into 222 nm as well. COVID-19 outbrake revealed the importance of UV-C in HVAC Industry. There is no doubt that UVC Radiation kills coronaviruses, the only question is "How to use UV lights in HVAC to fight covid-19 effectively?". Properly installed UVC Light Disinfection systems can deliver high UVC output, driving up HVAC system efficiency while improving indoor air quality at the same time.

LEDs & UV Light Wands Are Not Good UV-C Light Sources!

UV light application in air handlers is a good idea but also has its downsides. There is a lot of air that circulates in the room that doesn’t necessarily recirculate through the air handler immediately. Thus, pathogens build-up in the zone air.
