UV sterilization, discovered in 1879 to be a useful technology for cleaning infectious spaces, more studies were done to determine the exact beneficial nature of UV for sterilization purposes. Since the 20th century, UV sterilization has been used to disinfect things like water and work surfaces.
With today's technology advancement, UVC sanitizing has become much more accessible, portable and affordable. It is a proven technology that can aid cleaning and sanitizing.
HOW DOES UVC DISINFECTION WORK?
As evident by multiple research studies and reports, when biological organisms are exposed to deep UV light in the range of200 nm to 300 nm (UVC)it is absorbed by DNA, RNA, and proteins. Absorption by proteins can lead to rupture of cell walls and death of the organism. Absorption by DNA or RNA (specifically by thymine bases) is known to cause inactivation of the DNA or RNA double helix strands through the formation of thymine dimers. If enough of these dimers are created in DNA, the DNA replication process is disrupted, and the cell cannot replicate.
CELLS THAT CANNOT REPLICATE, CANNOT INFECT.
It is widely accepted that it is not necessary to kill pathogens with UV light, but rather apply enough UV light to prevent the organism from replicating. The UV doses required to prevent replication are orders of magnitude lower than required to kill, making the cost of UV treatment to prevent infection commercially viable.
It has been scientifically proven that UV-C energycan be used as sterilization technology to inactivate a wide range of pathogens (e.g. MRSA, C. diff, E. Coli and Pseudomonas). Studies have confirmed that UVC light can be effective for combatingSARS-COV(source). However, additional studies are needed to determine and confirm the specific dose response required to inactivate COVID-19 on different surfaces and materials.
AUTHORISED AND CERTIFIED PRODUCT.
QLEARPLUS+ is the official authorized retailer of UVC Sanitizing products from CleanTrust, who has carried out numerous years of research and testings in developing the NORYA and AJAX sanitizing devices. Both devices uses Korean made UVC LED Lamps and are certified by the most stringent and globally approved test facilities. View more information on test results and certificates in each of the product pages.
UV-C radiation naturally exist in the atmosphere. Through numerous studies it has been proven that UV-C exposure is unlikely to cause acute or long-term damage to human skin. However, align with most institutes including EU healthy agency's recommend we should not expose direct UV-C energy to human skin and eyes (source).
