The Germ Genie, mounted above a standard keyboard
According to a 2008 study conducted for England’s Which? magazine, computer keyboards can contain up to five times the amount of bacteria as toilet seats. This is particularly yucky news for users of public or shared keyboards, who are being exposed to other peoples’ bacteria. In settings such as hospitals, where doctors and nurses share keyboards, it’s a situation that definitely should be addressed. Fortunately, a study recently conducted at the University of Hertfordshire determined that an ultraviolet light device very effectively sanitizes keyboards.
