Why purify your tap water?

Tap water is not sterile, so it might contain germs. According to CDC, even when the public water system is working correctly, a small number of germs that naturally occur in the environment can still be present. 

You can take steps to help ensure the water your family drinks is safer⁵, purer⁵ and great tasting with Pureit reverse osmosis water filtration system.
