    The filters are awesome. They are very easy to install and one only needs to run water thru them twice

    We’re loving it thank you! So happy to have the real thing!

    The only issue we have is that the website for verification for authenticity wasn’t working.

    All was fine from the order to the delivery. I love the idea that the company will be sending us a message when it is time to replace our filters. So convenient. Thank you.

    The filters work but I was disappointed that the thread size was not compatible with adding my Berkey arsenic/fluoride filters under them.

  12. Jan D.

    These filters are great. If the Berkley filters were to come available again, I would not buy them. These are far better and no priming. And easier to clean. Besieged is the one to get.

  13. Rachel H.

    Amazing! Better than the original berkey I think!

  14. Colleen

    I usually buy Berkey filters but they’re on backorder. I bought these as a replacement and the water tastes just as fresh and delicious. I hear the filters don’t last as long though so I’ll likely switch back to Berkeys when I need a replacement

  15. Leslie

    Nice filters.

  16. Craig

    I bought these to replace Berkey filters after many years of using them. I had no idea that Berkefeld was the original. I will be using these from now on, thank you.

    Switching from Black filters.
    Seems a good change and shipping was easy.

  24. chris w.

    The filters flow well , just know that the setup initial flow will be very slow. the taste is great. The packaging was nice, I wish that I had measured my old filters. I purchased 7 instead of nine inch but very happy with my new filters. Thank God there is no flushing required. Peace

    It’s so nice to have clear water again! Thank you!!

    I was very impressed with the quality and the price. They filter fast and leave fresh tasting water in place of my tannic tasting water. I really like these filters.
