    Waited around awhile, then decided to purchase the Big+ now I wish that I didn’t Waite around awhile. Water tastes so good compared to the tap. Can’t believe I waited

    I didn’t realize how necessary water filters were until I moved to SLC and drank from the tap for a year, which is horrifying thinking about now. After hearing so much about a competitor brand, I researched the options and was surprised to see ProOne filtered more out than this competitor. After purchasing and then using it for only a short while, I started noticing visible differences in the skin reaction that the fluoride in the tap water was causing. Love my Big+ and couldn’t recommend it more!

    We’ve been pleased with the ProOne filter system. It was easy to assemble and works great.

  4. Cokie (verified owner)

    We just bought our first Pro One Big+ and have been using it for 2 weeks. Water tastes great, super simple assembly, and the spigot puts out a lot of water! I have a great sense of relief knowing that we are no longer ingesting all kinds of toxins every time we drink our water.

    We did a lot of research on the different units out there and came to the decision this is the best one. Only one other came close but it was much pricier. I received my Big+ unit the other day and was impressed with how it was packaged. I thought it might be missing some parts, but it wasn’t. Easy to assemble. We ran water through the unit three times as specified and on the fourth time, we tasted sweeet water. Can’t use it enough for all our kitchen needs! The spigot has a great design and feel to it.

    Delicious water! I am so happy with this filter system! Our water comes from an old community well system. The minerals stain shower grout and white laundry is impossible to keep white. I’m glad to know that the water I drink is free of these minerals and contaminants.

  7. Whitney Cook

    We’ve had our Big+ Gravity water filter for over a year now and we are still very happy with our purchase. It’s easy to access for the whole family, four kids included. I make sourdough at home and the filtration of our tap water has made a world of difference in the process. We love knowing that we have a supply of clean water at our disposal when we need it. It’s easy to assemble/disassemble and use throughout our day. Highly recommend!

    Great quality water filter. I can really taste the difference in my drinking water. I made my wife a believer, thank you ProOne.
