  1. Rick (verified owner)

    We love this water system. We are on well water and we use for a final filtration. Started with using all three filter slots but two is plenty for our consumption (5 person household). Thanks Pro One for a great product. Great looks and product finish.

  2. Erin D (verified owner)

    I absolutely love my pro one filter! The water tastes exponentially better than our tap water. We are a family of 5 and this is a great option for us! Moreover, the customer service at this company is amazing. I had an issue with a product delivery and promptly received a phone call as well as email and the issue was quickly resolved. 5 stars for sure and definitely recommend.

  3. Michael Rocco (verified owner)

    Huge difference over our tap water which is considered good. Kids noticed it, dogs noticed it and the pot belly pig notices it too. Going to try out the shower heads now.

  4. Ross Kempner (verified owner)

    works well!

  5. Ross Kempner (verified owner)

    It works as described. The set up was not so hard and it seems to work well. The filters are a bit fragile but if you’re careful then it is no problem.

  6. Adam Eckhart (verified owner)

    Pro One is a far superior system than Berkey. Having a combined filter / fluoride filter saves money and makes cleaning easier. I recommend Pro One over any other system on the market today.

  7. Megan Babaa (verified owner)

    We got this for our family of 4 and LOVE it!

  8. Jessica Schultz (verified owner)

    We have had our Big+ for a year now and we love it! Our filtered water tastes fresh and pure and I feel good providing clean water for my family.
