    I have confidence in the ProOne systems. I had gotten a small system for myself some years back and loved it. I’m on clean well water, so I sent it to my mother and she loved (still loves) it, too. She could really taste a difference between the clean water and city water. Then I got the same system for my oldest daughter a few years ago, but they were filling it 2-3 times per day. For a family of 6 they really needed something bigger. So I recently got her the largest system and boy was she happy. She then gave her smaller one to my other daughter.

    So far we have been very pleased with this water filter! Big enough for our family of 4. Easy to fill & maintain and the price is just right too!

  3. Ashley Knight (verified owner)

    We bought this a month or so ago and absolutely love it.
    The brushed silver is easy to clean.
    The water tastes so fresh. We bought two filters and plan to buy another.
    We just fill it at night and have plenty of water all day for our family of 5!
    Very happy we made this purchase instead of the competitor system.

  4. Ralene Anderson (verified owner)

    I recently purchased the Big + and I am very happy with it. Not only is the water great tasting, but it is piece of mind knowing that the water is safe to drink for the whole family.

  5. Cameron (verified owner)

    I’ve had the ProOne Big + gravity system filter for a couple of months now and I am incredibly happy with the product. Good, clean water is extremely important to me and I’ve got to say, this thing works. Besides the fact that public water contains all kinds of substances we don’t think about, growing up on a well it’s always tasted like drinking a swimming pool to me. The off-the-shelf filters do NOT work. The ProOne is the only filter system I’ve ever used or tasted water out of that works as advertised. I feel great knowing that safe, clean water is at my fingertips. My water consumption has doubled since owning the product. Thanks ProOne!

    Easy set up. Low maintenance. The spigot sometimes gets loose and I wake up to a puddle of water underneath. Just have to retighten often. Great company!

  7. Emily Lauer

    Love these filters and love that the water is actually purified and safe to drink. I started with a pitcher, but it was a bit small and a bit slow to filter, so great for 1 person for drinking water only. I switched to the larger gravity system to have more gallons per day.

  8. Susan

    BEST ever!…Great product; GREAT customer service; GREAT, GREAT water! Everything
    We tried a Competitor System prior to getting our ProOne; I was less than impressed….irate would be the more accurate word…..sent the whole kit-and-caboodle back. Did more research, got it down to two….decided on the ProOne and BOY am I glad I did. Nothing but happiness…if I could give it 10 waterdrops I would.
