Boeing’s self-cleaning lavatory zaps germs with UV light

It could be the cleanest bathroom in the sky, and you’d hardly have to touch a thing

Sourced through from:

For those who are worried about the cleanliness of airplane bathrooms (and who isn’t?), Boeing is working on a solution. This week it unveiled a prototype of a self-cleaning lavatory that zaps germs with UV light.  The company says it uses far ultraviolet light to kill 99.9 percent of germs on the toilet, sink and other surfaces where bacteria can lurk. It claims three seconds of exposure to far UV light is enough to disinfect all the surfaces in the room.  Far UV is not the same wavelength as the potentially damaging UVA or UVB light that you might find in a tanning bed, for instance.   “In the prototype, we position the lights throughout the lavatory so that it floods the touch surfaces like the toilet seat, sink and countertops with the UV light once a person exits the lavatory. This sanitizing even helps eliminate odors.”
