  1. Christina DiJulio

    We were gifted the same style but a different brand of water filter and were at first very grateful. After looking into the system and noticed what it didn’t filter out, I was shocked. My husband found you online and we were so impressed! Upon purchase and use, we continue to be impressed. I have received prompt, friendly and helpful customer service. The system itself is well-made, it works so much better than our previous one and our water is absolutely delicious. Thank you!

    Bought this for my parents house who get water from a well. Working nicely. Filter usage will go along way , about 18 months. I have one for my house , different model but works well. Both were very easy to install

  3. Doug (verified owner)

    We have a well, and I added this to our kitchen sink to filter the water we consume directly for drinking and cooking. While the initial results are that it seems to filter out some of the contaminants, the taste of the water remains. Perhaps I had a misconception, but I thought the water would taste significantly better. It doesn’t. However, I still feel better about having any contaminants removed.
