Does UVC Light Kill COVID-19?

by | Jan 28, 2021 | disinfectant

COVID-19 is rapidly evolving, and one of its newest strains may be up to 70% more contagious.

As time goes on, the pandemic only seems to be getting worse.

Schools, hospitals, and businesses nationwide are struggling like never before to find new methods of keeping students and workers safe.

People are starting to double-mask and lockdowns are slowly making their way back.

But what’s the most efficient way to get rid of these new strains, and can COVID-19 be killed with UVC light?

Let’s find out.

The science behind UV light

Ultraviolet technology is not a new phenomenon. It’s actually been used to sanitize research labs, hospitals, and several other high-risk areas for years now.

If you don’t work in the healthcare industry, you likely haven’t heard of or thought about this kind of technology prior to the pandemic. But these days, it’s everywhere you look; including Amazon, Costco, and even some drugstores.

If you’re new to the idea of UVC disinfection, it can be hard to comprehend how a simple light can kill germs. But it’s simple, really.

How it works

UV light is so strong that it can actually damage DNA, cells, and other biologic substances. This makes it an extremely powerful disinfectant–and dangerous to humans who are immediately exposed to it.

Because of this, UV bulbs sold for residential use are low-dose, making them safer for humans but also slower to act. Unfortunately, simply waving a UVC wand over your countertop will not do the job.

In order to fully sanitize a space, the UVC light must make direct contact with the area you’re seeking to disinfect. If the light is blocked by dirt, dust, or other objects, it might not be able to shock the entire space.

In hospitals, UVC robots like the Aura are used to zap patients’ rooms after they leave. Simply roll it into the empty room, plug it in, and in 15 minutes or less, it will kill up to 99.99% of viruses and bacteria within a 400-square-foot space. 

This type of technology can also be used to disinfect water and air. MERS, SARS (the virus causing COVID-19), and other surface and airborne pathogens don’t stand a chance against UV technology.

UV disinfection for air

UVGI air scrubbers like Spiro-Max are key for killing airborne viruses and bacteria. This type of technology goes inside of your HVAC duct and away from human contact. It runs 24/7, purifying air as it’s circulated through your facility and posing no safety risk to your occupants. Spiro-Max is also safe for use in cold storage rooms as well as warm, humid locations.

UV disinfection for water

In places like hotels and nursing homes where laundry is constantly being run, UVC technology like the LUX, LUMARS, and SULAOS are critical to maintaining safe and efficient operations. 

Aside from killing all viruses and bacteria on the linen and in the water, these systems can:

  • Save you money by instantly decreasing your energy and water consumption


  • Extend the life of your linen
  • Guarantee hygienically clean textiles and linen
  • Reduce your consumption of detergents and other cleaning agents
