Forget air "purifiers," those are sooooo outdated. How about an air disinfector? The English company Inov8 has invented the Air Disinfector, a gadget that essentially creates fresh air indoors. Marketed mainly at hospitals, it's currently available only in Europe but is being tested here in the U.S. with the intent of making it available here soon. About the size of a flower vase, the Air Disinfector works by creating reactive hydogen radicals and pumping them into the air, instantly killing microbes and bacteria in the surrounding air.
