UV-C LEDs provide astronauts with clean water in space
Astronauts on the International Space Station are drinking water that meets strict health standards thanks to UV-C LED technology.
UV-C is a type of ultraviolet light that emits radiation in the electromagnetic spectrum between 200-280 nanometres. It is invisible to the human eye and highly effective at neutralising pathogens, such as bacteria, viruses and protozoa. When pathogens are exposed to UV-C light, it stops their DNA from reproducing and duplicating, which means they cannot multiple, and deactivates them in seconds.
