The New Oreck HaloTM The New Oreck Halo uses UV-C light to kill many of the germs on your floors while you vacuum. It's one thing to get rid of visible surface dirt, but the new Oreck Halo with its specially designed UV-C light chamber can kill many of the germs, bacteria, mold, dust mite eggs, and flea eggs on your floors - in just a few seconds. And it's chemical-free.1   The Oreck Halo can reduce up to 99.9% of bacteria and up to 90% of dust mite eggs on surfaces. The New Oreck Halo uses the same ultraviolet technology used for decades to purifiy drinking water and help sterilize the air in hospitals. And in laboratory testing, the UV-C light from the Oreck Halo light chamber reduces up to 99.9% of bacteria and up to 90% of dust mites eggs on surfaces.   The patented Oreck Halo light chamber magnifies and concentrates UV-C light to kill many of the germs that could be living on your carpet.2 You can't see these microscopic nuisances in your carpet or on your floors, but when they're exposed to the patented Halo light chamber, many of them are killed. Best of all, those microbes are then vacuumed up without a trace, thanks to superior Oreck vacuum technology that removes dirt, dust and debris just like all of our trusted vacuums. “With each back and forth motion of the Oreck Halo, you'll see up to an 80% reduction in the bacterial load found on carpet.” - Dr. Stan Kikkert, Microbiologist The three petri dish images above represent the positive results of repeated exposure to the Oreck Halo light chamber. With each pass (a back and forth motion of the vacuum), the bacterial load on carpet is reduced by up to 80%.3
