Hospitals use a certain kind of ultraviolet ray (UVC) to kill germs. Now a small UVC wand is available for home use.
How it works. The Light Wand by Germ Guardian ($100 at online stores) harnesses these rays to kill up to 99 percent of germs, as well as eliminate allergens such as mold and dust mites. “UVC works by destroying the genetic material of the organism. It breaks apart molecular bonds in the DNA and damages it beyond repair,” says Jonathan Sexton, a research associate at the University of Arizona, who studies germ-busting products.
Where to use it. Besides the bathroom and kitchen, it can be used on bedding, keyboards, furniture, toothbrushes, even shoes. Plug it in (or use batteries), and hold it over the area for around 20 seconds.
Do you really need one? The wand is no substitute for regular cleaning. But it may help if someone in your home has severe allergies or lowered immunity.
