The Purleve hygienic handle makes the doorknob the cleanest thing in a public restroom, when usually it harbors thousands of infection-causing bacteria. The system stores thousands of spooled sterile plastic sleeves inside. After someone uses the handle, a motor within the handle mount draws the used plastic sleeve inside, dispenses a fresh sleeve up through the center of the hollow handle, and turns the sleeve inside-out as it unrolls over the handle’s exterior. For good measure, the sleeves contain Microban, an antimicrobial agent that kills 99.9 percent of germs and keeps the used sleeves from contaminating the new ones.
