EPA scientists are pressing ahead with research into the use of ultraviolet C (UV-C) light as a disinfectant against COVID-19 -- an approach that has garnered interest from at least one major public-transit agency -- but say the technology remains a work in progress and more study is ne...
UV light disinfection device, for a personal workplace or lounge with at least one lighting device (1) and with at least one UV light source (2, 3, 4) assigned to the lighting device (1), characterized by a control device (4) providing the UV light source (2,3,4), 3) switched ...
For years, doctors and health professionals have been using ultraviolet light as a disinfectant. Now, a major ceiling fan manufacturer is mounting UV lights onto the base of its smart ceiling fans, and promising they can rid a room of viruses and bacteria within minutes. The company is...
As evident by multiple research studies and reports, when biological organisms are exposed to deep UV light in the range of 200 nm to 300 nm, the UV is absorbed by the DNA, RNA, and proteins. Absorption by proteins can lead to rupture of cell walls and death of the organism. Absorption...
light that is usually invisible to the human eye. This light is found in the electromagnetic spectrum between the x-ray and the visible light. Although this light is not visible to the human eye, it can be used as a disinfectant against microorganisms such as bacteria, protozoa, and viruses...
By Pratibha Sharma, Ph.D., Saya Han and Peter Chung, Violumas Ultraviolet light is a known disinfectant, which reduces microbial load by denaturing pathogenic DNA. Wavelengths in the deep UV range, from 100 nm to 290 nm, with commercial devices available

Action Furnace is promoting UV as a disinfectant for viruses, but doesn’t name COVID-19 specifically, because there are no studies yet proving UV’s effectiveness inactivating this novel version of the coronavirus. However, there are ample studies proving UV’s effectiveness against viruses and ...
or taste, nor does it generate harmful by-products. It only imparts energy to the water stream in the form of UV light to accomplish the process of disinfection, TOC reduction, ozone destruction or chlorine/chloramine destruction. UV disinfection produces no residual disinfectant to the finished ...
UV-C radiation is one of three types of UV light, its wavelength causes damage to the cell membrane and disrupts the DNA of viruses and bacteria and destroy them. This germicidal radiation therefore has disinfectant features. As it is a UV light, it is able to disinfect al...
