Customer review

I bought my first one three months ago and have since bought TWELVE more for my family members and friends. My brother has one in his dorm, I have one in my apartment in NYC, one in my husband's house in Atlanta...I could go on. This is the most perfect filter I've found for what I need. I installed it myself (thank you for that video, it was really simple to install after watching it) and I can just get really tasty water from my faucet now. The first two weeks in NYC I had to carry cases of bottled water from the grocery back home and it was a huge pain the @$$. These things are awesome!!
