Do I still need to boil my water if I have a filter system on my faucet or refrigerator?

Most point-of-use (POU) filters are designed to improve the aesthetics of water (improve taste and odor), not remove harmful bacteria.

You can learn about the capability of your filter by contacting the manufacturer, or NSF International, an independent testing group located in Ann Arbor, Michigan. To reach NSF International, call 800-673-8010 or visit the NSF International website for more information.

If in doubt, you should boil your water or use bottled water even if you have a filtering system.
