  1. mrme

    All good, works great.
    Easy to assemble. Tools are included.
    Consider using one filter at a time for $ savings, especially if you have low consumption.

  2. Andrea Meyerhofer

    We have 3 filters inside, and our water tastes so clean. Easy to assemble and we fill it daily (we drink a lot of water!) Be sure to clean the unit on the recommended schedule.

  3. Leila Hayashida

    Best filter we ever had. The water is clean and tastes just like pure water. Strong recommended!

  4. Lauren (verified owner)

    Water tastes so clean! My husband would not ditch bottled water until we bought this. Easy to assemble and use! Would highly recommend!

  5. Rebecca (verified owner)

    Incredible water filter! My entire family loves it so much. Highly recommend investing in this system. The water has a great taste. I can now tell a difference if I drink non filtered water compared to drinking from our Proone.

    Amazing Filter. Tastiest water I’ve ever had! I’m so glad I made the choice to purchase this water filter, now we always have fresh clean tasty water!

  7. Carrie Jones (verified owner)

    We love our Water filter. We have well water and it’s amazing how it filters the rust out of the water. The water tastes amazing. We just bought our second one for our other house and can’t wait to get to using it. I plan on getting a shower head next.

    I LOVE my ProOne!!! The water is just terrific! I really like the fact that I only need to buy one filter that includes fluoride. I also recently found out that ProOne filters out Roundup too. Yay!!!!
