Are you worried that dangerous germs could be lurking in your bathroom, your kitchen ... even in places you don't know about? You might not be able to escape them, but that doesn't stop people from trying. Americans spend more than a billion dollars a year trying to get rid of germs, but as Dr. Keri Peterson points out, not every germ is bad for you. "There's a perception that we have to eliminate all of them in our environment," she says. "There are only four classes of germs: bacteria, viruses, fungus and protozoa, and it's the bacteria and the viruses that can cause illness, so this is really what we're looking to sanitize." Rachael has three viewers test products that claim to reduce the number of bacteria and viruses in your home.

• Gaby, 39, works in a medical office where she's always handling paperwork, pens and money back and forth with patients. "I'm most concerned about germs on the phone," she says. "I'm constantly wiping down the area just to keep it free from germs. It would be wonderful if I could have some proof to show me that the germs are gone." So Gaby tests the Germ Guardian UV-C Sanitizer Wand that claims to kill up to 99 percent of the bacteria and viruses with just a wave of the wand.

• "As a mother, germs are a huge concern for me," expresses Ginger, 35. "They're everywhere." This mom's front door opens right into her kitchen, where she worries about germs the most: "Even when I get my countertop to shine, I still wonder what kinds of germs are still there or if it's really clean." So Ginger tries the Lotus Sanitizing System, which claims to sanitize homes naturally without the use of any chemicals.

• Mike, 26, shares his bathroom with two male roommates. "You can imagine how hard it is to keep it clean!" he jokes. "My toothbrush is more susceptible to germs because it's right next to the sink and exposed to everything." So Mike tries the Zapi Toothbrush Sanitizer, which claims to instantly sanitize your toothbrush using UV light.
