With Germ Guardian's LW-18 UV-C Sanitizer Wand you can now kill 99% of viruses and bacteria without the use of chemicals. The UV-C Sanitizer wand can do more than just kill dangerous viruses and bacteria, it can also fight unwanted odors and allergens. UV-C is natural and also poses no threat to humans or pets so you don't have to worry about adverse side effects. The secret to all this germ fighting power is the UV-C technology. UV-C light kills germs by penetrating the thin walls of viruses and bacteria. Once it has penetrated the walls the UV-C light alters the genetic structure of the organism which causes the organism to die. This is also how the Sanitizer Wand is able to fight odors and allergens. Germ Guardian's Sanitizer Wand works off of 4 AA batteries that are not included with this purchase. It also has a power adapter with a 6 foot cord. This is the ideal way to sanitize pillows, bedding, toys, cell phones, computer equipment, toilets, showers, sinks, countertops and even shoes.
