  1. pts admin

    Product arrived damaged. The berkey is extremely scratched, all over the entire inside and outside. It had marks, weird stains and fingerprints all over it as well. The box was very discolored, an old dingy off white color. The box was so old it was coming undone at the seams and smelled horribly. It smelled like we would imagine rat feces to smell like. Also, the water bottle wasn’t included. We didn’t even unwrap the filters, not sure of the condition of them. Do NOT order this product from this seller!!! We have already dropped it off to return it. Absolutely disgusting used condition.

  2. Babrara A

    Nice-looking product, although mine came with a significant dent in the upper chamber. I can taste a significant difference in the water from the Berkey vs. filtered water from my refrigerator. I bought this filter with the goal of reducing heavy metal toxicity in my body. Hopefully it will help.

  3. rona asman

    Small, but not really for “travel”. You would do best to disassemble it before driving with it as the filters will fall off, and there is no way to know if they got damaged inside. I drove with it in the front seat, inside a bucket with pillows and secured with seat belt. The Fluoride filters fell out, thus contaminating whatever water had been filtered. Not sure if they were damaged.
    Do not think this is for TRAVEL.
    Very nice for home use.
    Fluoride filters seem slower than just the primary black filters, so plan ahead. I fill at bedtime.

  4. Osvaldo Hernandez

    What a great product and will pay for itself in less than a year! Great tasting water too.

  5. anji treadway

    little bit of setup time required, but works great. I wish they sold a visible water level tube for the stainless faucet though……

  6. Shirley Familetti

    Seems to be working well. It appears that the package was a returned item but all components were there with new filters.

  7. Dm Bailey

    It didn’t include the stainless steel water bottle in package

  8. Linda VandeVrede

    Excellent, just as the other two models I have.

  9. Evelyn Gonzalez

    Thrilled I bought this! Great way to always have clean water. Now I don’t have to buy so much bottled water.

  10. Annette Brown

    Perfect for a house of 2 (heavy water consumers: 1.5 qtr bottles of water each daily, plus cooking, daily tea and coffee) – SUPER clean and great tasting water. The stainless steel spigot is fantastic – great flow, no dripping after use (like the black plastic), and super easy to install. Priming the filters wasn’t my favorite, but the holy water as a result is worth it!

  11. Amy Wilmer

    Great filter. Looks nice on the counter. Good packaging.

  12. Kathryn Garcia

    You will drink a lot more water with this it taste that good!! Cook with this water, make coffee or tea with this water! Everything will taste better. Your PH levels will go up which will reduce inflammation and prevent a lot of problems and maybe diseases with your body. Babies need this in their formula or breastfeeding moms need to drink this water. Everyone needs to drink this water!! It did take a long time to prime the fluoride filters so I submerged my filters for a couple of days in a tub of water than installed them. Fill the top tank than you may have to wait a few days before it starts working. Well worth the wait. My 15 year old son would not drink water but now he is. I got this one since it has the stainless steel spigot, no carcinogens! We also got stainless steel bottles to drink our water from.

  13. Kristy Loman Chiodo

    We’ve been using our Royal Berkley for about a month now. It’s been wonderful. We’re a family of four and it’s the perfect size for us.

  14. linda johnson

    Love this filtration system. Simple to use once it is set up. The instructions were a bit confusing and seemed to be lacking some information, but figured it out. Also a bit difficult to “prime” the filters, but once it was set up, it is very easy to use. Water tastes great and good to know that it is actually clean.

  15. Julie Spataro

    Easy to install, nice stainless finish (also bought the stand) with the matching tap. Water tastes completely different.
