Ultraviolet, or ‘UV’ lights have been used in air purifiers for many years in an attempt to disinfect the air and kill harmful viruses. Unfortunately, UV light air purifiers have various disadvantages. Here we explore how UV light air purifiers work, how they kills viruses and give reviews of UV light in respect to the best solutions for air filtration.
Air purifiers with UV light are marketed as effective virus killers, capable of targeting viruses such as COVID-19. UV light technology including far-uv, far-uvc, and UVGI are advertised to kill 99.9% of viruses. One in every four air purifiers displayed as top results on Amazon is labelled as a UV-C …
In the other article‘Common UV Lights Aren’t Great at Killing COVID-19’, we explained how much doses do we need to kill coronavirus. Also, we talked about how UV-C light kills the virus. Also, the UV light we can find in the market is too weak to kill the coronavirus. So, …
UV light, or ‘ultraviolet light’, is a form of non-visible electromagnetic light. The main source of UV is the sun. There are three types of UV light: UV-A, UV-B, and UV-C. They’re differentiated by the wavelength of the light, with UV-A light has the largest wavelength, ranging from 315-400nm. UV-C …
UV light has surfaced as a potential solution for destroying the coronavirus and other viruses alike, but are common UV lights strong enough to be effective? How much of a dose do we need? We took a careful look at the data and came up with practical guidelines. Using UV …
