We actually have city water but it's got soooo much iron in it you can't drink it! I was spending so much on bottled water it was ridiculous! So I was truly excited to try this product! And it didn't fail! I'm actually saving money with the bottled water I'm no longer buying! The water is much more clear and the taste! The taste is BETTER than bottled water! Very easy to install, which I was very happy with, and no problems at all after installation! This is a MUST HAVE! Highly recommend this filtration system!
