The Dirt Devil Purpose for Pets Portable Extractor has a special black light that finds hidden pet stains you can't see. "Pet stains contain odor-causing bacteria, so it's important to remove them," says Forte. "Often you can't see them, but your pet knows they're there and will go back and stain the same place again. So with the black light, you find the stain and know you've gotten it out."

If you're concerned about your home's drinking water, Good Housekeeping recommends the Kohler Carafe Filtered Water Kitchen Faucet. "What we like about this faucet is that you can get either filtered or unfiltered water from the same tap. So if you want to take a drink, certainly you want to filter your water. But if you're washing dishes, you don't need filtered water. You can use it unfiltered and extend the life of a filter."

Want to prevent the spread of bacterial infection at your computer? Good Housekeeping recommends the Seal Shield washable computer keyboard and mouse. "It can be a real pain to keep your keyboard and mouse clean," says Todd Kent, engineer, Good Housekeeping Institute. "If you spill coffee or soda or eat your lunchtime sandwich over the keyboard, it can get really messy. A great thing about this keyboard and mouse is you just stick them into the dishwasher or wash them in your sink and they come out like new."

And Good Housekeeping says Vick's Germ-Free Humidifier uses an Ultraviolet light to kill virtually 100 percent of bacteria. Although the humidifier does kill most bacteria, you still need to clean it. Ideally, every day you should drain, rinse and refill the humidifier's reservoirs and tanks.
