#FAR UVC LAMP SKIN#
With the proper use of an optical filter to eliminate harmful UV wavelengths, this study confirmed that filtered 222nm Far-UVC light is safe for humans and does not induce skin damage.Ī Eadie et al case study also confirmed the criticality of an optical filter to ensure 222nm-Far-UVC safety by tests on human skin. patents covering apparatuses and methods for. This study by Bernard et al concluded that skin damage documented by Woods et al arose from very low intensity source emissions above 230nm due to the lack of an optical filter (as low as 3% above 250nm). Ushios Care222 filtered Far UV-C technology (Care222 Technology) is protected under U.S. These wavelengths were emitted as the 222nm Far-UVC emitting device did not utilize an optical filter to eliminate wavelengths outside the 200nm to 230nm range (the safe wavelengths), with wavelengths below 200nm and above 230nm being unsafe.
It can be used for about 8 hours The Far UVC lamp is tested multiple times following all the standard rules and regulations, which proves that people can use this. Some of the most crucial features of the Far UVC lamp are specified below. Woods et al hypothesized that a small amount of longer wavelength UVC light above 250 nm (<3%) may be contributing to the observed effects. The Far UVC lamp is one of the best Far UV solutions for killing both airborne and surface pathogens. The study concluded that damage was induced on human skin. A direct way to limit the spread of airborne viruses is to inactivate them for a short period of time after they are produced. This ultra high purity quartz glass bulb delivers optimized 2-800W 222nm UV-C. 2 Far UVC light (222 nm) effectively and safely inactivates airborne human COVID-19. In 2014, Woods et al undertook a first‐in‐person study to assess the effect on skin of a 222nm Far-UVC emitting device (a disinfection wand). DescriptionUV Cans HELIOS is a Far UVC 222nm excimer lamp. Beginning with hand sanitization in medical institutions, it is expected that this technology will have a wide range of antiviral and antibacterial applications in places that people enter, such as schools, welfare facilities, food factories, toilets and kitchens.This study by Barnard et al emphasizes the importance of using an optical filter to ensure 222nm Far-UVC safety, proving that filtered 222nm Far-UVC is safe but unfiltered 222nm Far-UVC is not. These research results indicate that even though 222-nm UVC is a powerful sterilizer, it can also be used directly on human skin. On the other hand, it was shown that 222-nm UVC doesn’t damage the DNA of skin cells because it only travels as far as the stratum corneum, the outermost layer of the skin. This unit is ideal for use in hospitals, clinics, nursing homes, restaurants, schools, food processing facilities, office buildings, and many more. The 254-nm UVC currently used in germicide lamps penetrates down to the basal cell layer, the bottommost layer of the skin, and damages the DNA of cells. The revolutionary 222nm FAR technology provided by this unit is a safe and harmless visible ultraviolet light that demonstrates an effective method for supressing a wide range of potential applications. It was understood that 222-nm produced no adverse effects due to the level of skin penetration. There were no abnormalities visible, even when examined under a microscope (Figure 1). The effect on their eyes was investigated in cooperation with Shimane University’s Department of Ophthalmology (Professor TANITO Masaki et al.). In the group that was exposed to UVB (280-315 nm), the wavelength range equivalent to skin cancer caused by sunlight, all mice developed skin cancer and displayed adverse effects such as cataracts and cornea damage.Ĭonversely, mice in the 222-nm germicide lamp group did not develop skin cancer at all. 2.High efficient germicidal lamp, preventing regrowth of bacteria. Ushio is proud to introduce the Care222 series, a new line of krypton chloride (KrCl) excimer lamps designed for highly-effective microbial reduction. To evaluate the safety of repeated eye and skin exposure to a 222-nm germicide lamp, xeroderma pigmentosum group A model mice were used in this study.Ĭompared to wild-type mice, these model mice have an increased sensitivity to ultraviolet radiation and an over 10,000 fold increased risk of developing skin cancer. Advantages: 1.Monochromatic and narrow-line emissions.
