The Science of UV-C
The body of science shows that exposing air and surfaces to UV-C light for a certain period of time (the “dose”) can be very effective.
Every UV-C light puts out a certain wavelength of light. The UV-C range is 200-300, and the most ideal wavelength for killing most bacteria and viruses is 265nm. The traditional UV-C bulb lights put out 254nm. CleanRide UV-C LED light puts out 275nm. Studies have been conducted and have shown that there is not much of a difference in effectiveness within that 254-285nm range and that all the wavelengths are just as effective.
This study compares various wavelengths:
For additional uses, please review recommended doses for specific disinfecting applications.
