    Filters work as advertised.

    I’ve been using the ProOne gravity filter for almost a decade. Beyond the wide range of toxins it filters out of the water, it makes the water the best I’ve ever tasted,, definitely better than any bottled water. I’m a customer for life!!!

  3. Trish Walters

    I did a lot of research before buying a water filter pitcher and ProOne (ProPure) was the best as far as filtration. I loved mine so much I purchased one for each of my kids who were out of the house. At Christmas every year I purchase a replacement filter and will only buy here. Filters arrived quickly, and I know I am receiving authentic products since ordering directly from the manufacturer.

    This filter works great! I have the Traveler and am so addicted, I take it on beach vacations with me. The family thought I was crazy until they compared two glasses of water, one from the tap and one from the filter, they never touched the tap water again. When compared, the tap water looks visibly yellowish brown. I also love the lab work provided by ProOne- it helped me decide between this and a competitor filter!

    I’ve been using this filter for three weeks and it is the best one I’ve used so far. I really like that it ships dry unlike another brand I had tried. It filters very well. The water from the faucet smells terrible and after I run it through this filter, the water tastes and smells clean.
    It was easy to install and didn’t require any help to start filtering the water.
    Definitely will buy this filter again and again.

    We love this water filter! So amazing!

  7. Daniel

    The water tastes great! It looks really nice on the counter and the family loves it. Goodbye to expensive water bottles.

  8. Paul (verified owner)

    Our water comes from artesian springs and is reported to be some of the best in the country. I know fluoride is added and wanted to filter it out. The difference of the filtered water was amazing, the best tasting water I’ve had.

  9. Steve Young

    Great product

  10. Heidi Howe (verified owner)

    I love the way my water tastes using these filters. They are easy to install and clean. I like having fluoride-free water.

  11. jeanine

    I love my pro one pitcher and g2.0 filter, very convenient for a one person household, and you can taste the difference in the water immediately. Takes out more unwanted chemicals than most brands. Very happy with this one.

  12. Mike Simmons (verified owner)

    Excellent product!! A+ company

  13. Jonathan H. (verified owner)

    I re-order these filters for the Traveller filter system and they work great. I have peace of mind knowing that the fluoride and heavy metals are being filtered out, especially with little ones drinking it.

  14. Guillaume Avrillon (verified owner)

    I’m glad these filters exist, no more plastic bottles and for sure no more Fluoride in my tap water! My three children approved the taste of the tap water too.

  15. Nile

    long lasting

  16. clifton strautman (verified owner)

    I have been using the original G2.0 for 6 months now, and the filter is still going strong. I already have a replacement filter standing by for when the original filter finally needs changing…but not yet. I’m very happy with this filter system!

  17. n734372-8748 (verified owner)

    Taste good water. Easy to install. Very convenient to not need to add fluoride attachment underneath like other brands’ filters.

  18. Megan Lamon (verified owner)

    I use these in place of my Berkey filters and they work great. No complaints and the company is responsive and helpful.

  19. Stephanie Mullenmeister (verified owner)

    After years of heavy lifting of water bottles, I am happy to have replaced my water need with this filter system. Have been using it for years and love it.

  20. Sharon Bruyere (verified owner)

    Customer service was excellent when I was not sure which one to buy for my Berkey system. Quick and explained and even left a coupon code for purchase. Super happy with this company and so far with the quality of water!

  21. CHRIS WEIGAND (verified owner)

    I`ve been using these since they were Pro-Pur, maybe 15 years. Excellent. And the customer service was great when one I received was leaking. They sent me a replacement with no problems. I started using them because the filters like Brita have a chemical for keeping bacteria/fungus down. These apparently have silver.

  22. Andrea Lee (verified owner)

    I’ve used other water filters and these are the best. The water tastes amazing!
