Explained: How UV-C Disinfector Can Kill the SARS-CoV-2

01 Dec 2021

Sars-CoV-2, which resulted in the global pandemic, can be removed using UV-C disinfectors, according to a study done by Boston University. It describes how effectively UV disinfection of air and surfaces can mitigate the spread of coronavirus.

 

UVC radiation has commonly been used for many years to limit the transmission of bacteria and viruses. Due to its disinfecting effects, UVC lamps are often used in advanced air purification systems, engineered to kill indoor air pollutants, allergens, and airborne germs.  

In a new research, Boston University comes to a stopping point that UV-C allows a log 6 reduction of the SARS-CoV-2 that is equal to 99.999% of filtration efficiency. It says that the radiation disrupts the RNA structure of viruses and bacteria, and inactivates their effectiveness.

“Our test results show that above a specific dose of UV-C radiation, viruses were completely inactivated: In a matter of seconds, we could no longer detect any virus,” says Anthony Griffiths, associate professor of microbiology at Boston University.

Ultraviolet light:

Ultraviolet radiation is divided into three categories based on its wavelength: UV-A, UV-B and UV-C.

·        UV-A radiation: 315–400 nm

·        UV-B radiation: 280–315 nm

·        UV-C radiation: 100–280 nm

These days, UV lamps are largely used to enhance the effectiveness of disinfectors and sterilizers. Although such high-end disinfecting systems have got their way into residential and commercial use for enhancing indoor air quality.

How are UVC Lamps Used to Inactivate the Variants of coronavirus?

Since UVC Lamps can effectively inactivate the new coronavirus with no chemical used, therefore it has emerged as one of the most useful options for disinfection. At present, the application of UVC lamps for disinfection is generally confined to healthcare sectors—yet some high-end air treatment systems are engineered with a UVC disinfector to reduce environmental pollution more effectively.

Several manufacturers are using this innovative technology in home air purifiers to make them effective against microorganisms, but a few have come up with a perfect solution. One example is the PetriMedCA Air Purification, which uses UV-C disinfector in combination with HEPA H14, air ionizer, high quality activated carbon zeolite filter, and nano-silver antibacterial layer. It’s a complete fully-loaded system that can reliably be used to disinfect the indoor environment of hospital rooms, hotel rooms, Gymnasiums, offices and homes.

The bottom line

Most of the research on the effectiveness of UVC lamp against SARS-CoV-2 conclude that it is efficient to destroy SARS-CoV-2. Since it is largely used in healthcare organizations to disinfect surfaces, operating rooms, and equipment, you can also use it for your home or offices by selecting PetriMedCA Air Purification Systems that use a UVC disinfector.
