Does UVC Disinfection Work on the Delta Variant?

by | Jul 15, 2021 | disinfectant

Just as America was starting to get a grip on the Coronavirus, the Delta variant came into play. 

Based on hospitalizations in the United Kingdom, this COVID strain has proven to be more contagious and deadly than previous variants–even presenting with different symptoms (e.g., runny nose, sore throat, headache) in certain cases. 

The Delta variant is 50% more contagious than the Alpha variant, which was already 50% more contagious than the original Coronavirus discovered in 2019. 

The reason this strain is so contagious is because its mutated spike proteins infect human cells easier. 

At this time, the Delta variant is the dominant strain in the United States.

So how do we kill it and keep the Coronavirus from mutating into stronger, more dangerous variants?

Fortunately, the Delta variant can be disabled by UVC light just like the other strains.

Let’s take a look.

How UVC disinfection works

UVC light has been known to kill Coronavirus on surfaces in seconds and was recently discovered to kill airborne viruses as well.

This incredibly powerful light inactivates germs and bacteria using UVC wavelengths of around 254nm. 

It destroys the outer protein layer of the virus, making it no longer a threat to human health. UVC light is so powerful that it should not be used when people are in the room. 

UVGI air scrubbers, like Spiro-Max, utilize this light to continually kill airborne viruses as potentially contaminated air flows in and out of the unit.

UVGI air scrubber placement 

When using devices like Spiro-Max, placement of the machine is very important. 

You’ll need to consider the airflow pattern of the room as well as the location of the device so that it’s able to efficiently deliver a sufficient dose of irradiation to the contaminated air. 

You’ll also want to be mindful of the room’s furniture layout to stop UVC leakage from creating hotspots where people will be sitting for extended amounts of time.

Additional benefits of UVC disinfection

Disinfection isn’t the only benefit of UVC light. 

When used to treat water, this revolutionary technology can also help you decrease your energy, detergent, and water consumption in big hotels, laundry facilities, or nursing homes.

It keeps colors sharp and is great for stopping the spread of disease in linens and other laundry shared among residents.

UVC disinfectant is also chemical-free, so it’s completely safe to disinfect water, air, and surfaces.
