The Big Berkey Water Filter


The Big Berkey is our most popular system mostly due to the fact that it's a perfect size for 2-4 people.

Our Big Berkey system is constructed of highly polished 304 stainless steel and comes complete with 2 Black Berkey purification elements (expandable to 4), 2 chambers, lid, a spigot, rubber gasket base, and 2 blocking plugs. Up to 4 PF-2 Fluoride and Arsenic filters can be installed into the lower chamber.

More About The Big Berkey

The black berkey elements that come standard in this system purifiy both treated water and untreated raw water from such sources as remote lakes, streams, stagnant ponds and water supplies in foreign countries, where regulations may be substandard at best. This Berkey Water Filter is our most popular system and is perfect for everyday home kitchen use, outdoor activities, and a must in hostile environments where electricity, water pressure, or treated water may not be available.

This system removes pathogenic bacteria, viruses, cysts and parasites entirely and extracts harmful chemicals such as herbicides, pesticides, VOCs, organic solvents, radon 222 and trihalomethanes. It also reduces nitrates, nitrites and heavy metals such as lead and mercury. This system is so powerful it can remove food coloring from water without removing the beneficial minerals your body needs. Virtually no other system can duplicate this performance.

    1. Big Berkey Review by Vern

      I am 100% satisfied with my purchase, I went for the Big Berkey, there's just my wife and I, now I know I could have gone with the smaller one, but that's ok, so if there is just two of you, the one smaller will do the trick. I got jus the two filters and the flow rate is great, you will have all the water you want. I did the red dye test and it's amazing how it filters out the red, my test went fine. I didn't have any problem putting it together, I didn't even read the instructions, but I suggest that you do. I also ordered the sight glass spigot which I highly recommend. Over all, you will not regret buying this water filter and it's pretty too. (Posted on 2/14/14)

    2. will not drink fluoride Review by Pauly

      My parents got me this for Christmas since I've been outta work for about 6 months and didn't think I would be able to afford this. After about 6 weeks of use, all I can say is wow! It's very basic, but the water tastes like a cold mountain stream on a hot summer day. And now I don't have to poison myself with fluoride on a daily basis! (Posted on 2/13/14)

    3. Best filtered water Review by Amber

      The Big Berkey is such a blessing. We have owned ours now for almost a year and don't know how we did without it. We love how clean the water tastes and we also have the fluoride filters. When we go on trips, we bottle our Big Berkey water and take it with us to avoid drinking tap water and other bottled water. This is truly an amazing product. Thank you! (Posted on 12/9/13)

    4. Refuse to drink water from the tap Review by Mary Dixon

      Ever since letting the four legged/fur-bearing children have a sip of water from Big Berkey, they have refused to drink water from the tap. I know they have to know something the humans can't sense. Now, I won't deny them water from a Berkey and I know better to just keep using the same water I give to the animals. Am I nuts? Well, I dunno about that. But other humans might want to pay attention to the animals. Heck, the animals would drink from a mud puddle and the Berkey water but not from the tap.

    5. So Happy I Bought This! Review by Natalie Larson

      I'm on disability and it took me 3 months to save up for the big berkey and I'm so happy it's as good as I hoped it would be. I'm drinking more water that I ever and it's giving me more energy. I think I was chronically dehydrated and didn't even know it. Very satisfied! (Posted on 10/2/13)

    11. Love my Big Berkey Review by annieboat

      I have been wanting a Berkey for a few years but never took the plunge..Recently I have been drinking water instead of soft drinks..I never really cared much for water..Tap water was out of the question for me so I bought bottled water for a couple of months..What a hassle with all those plastic bottles..I finally ordered my Berkey....I love it...I wish I had bought mine years ago.

    13. Good Investment Review by Jack Sperry

      I wanted to follow up with a review after having this filter for about 3 months now. I absolutely love this filter and am so glad I purchased it. I find the taste of the water to be really clean and I will only drink water from my berkey now. I can tell a major difference between this and my city water! Very happy I made this investment. (Posted on 2/1/12)

    14. Buy With Confidence! Review by Brenda Folk

      I hesitated to buy this system for a number of reasons; price being 1, and I also wanted to wait and see what my neighbor's royal berkey looked like. After I tried her water, I was really impressed with the taste. I'm not sure what other customers experience, but I thought it was very clean and refreshing. So, I went ahead and ordered the big berkey with 4 filters. I should have bought this 5 years ago and I'm kicking myself for all the money I wasted on poland spring. The customer support has been great too. They have been pleasant and informative and answered all of my off the wall questions very nicely and promptly. Buy with confidence and do it before another disaster strikes and you can't get a hold of one. (Posted on 9/27/11)

    17. I LOVE IT!!!!!! Review by Shannon Guss

      I bought my Big Berkey in March of 2010. I use it to filter all of my water coming out of the tap. Now everything taste better. Even my coffee. Before you could taste the chlorine in the water, NOW YOU CANT! Thank you! (Posted on 9/12/10)

    18. Worth the wait Review by John Knight

      I ordered this system when it was out of stock and really looked forward to receiving it. I finally did and was completely worth the wait. I actually look forward to drinking water now. I got the 4 filter system with the 4 fluoride filters. (Posted on 6/27/10)

    19. Got this system a month ago Review by jason seligman

      I was skeptical at first considering i always drink from either bottled water or from my filtered refridgerator. This system is great. as far as improvements..i would recommend a handle on the upper cannister for easier lifting since it is a little slippery sometimes. I would recommend this product and this site. fast shipping and pleasant emails. (Posted on 6/18/09)

    20. We Love Our Big Berkey! Review by Annie Patterson

      I cant believe we waited so long to purchase one! We've been buying distilled water refills in those plastic jugs for years now. Could have saved tons of money and had better water if we'd purchased a Berkey sooner. I like how pretty it is, too. Also, great customer service and fast shipping, even to the top of Alaska. Thanks!! (Posted on 3/28/09)

    21. I had heard... Review by Rich

    22. I love this product... Review by Elena Scott

      I love this product. I bought it to match my stainless steel appliances that my new apartment had, and it looks great. Not to mention the water tastes great. I'm surprised how much the filter changes the taste for the better. (Posted on 10/15/08)

    Questions on Big Berkey

    • From Paula at 10/22/13 1:24 PM
      • Is this a reverse osmosis system? Are minerals taken out or put back in to water?
      • Hi Paula -

        The Berkey is a gravity filtration system. Minerals are not removed from the water, so there is no need to add them back in unless you would like to increase the mineral content of your water to be higher than what your source water provides.

    • From becki at 10/24/13 8:47 PM
      • I'm confused on the filters. If I get two filters will it work, or clean, my water as well as four filters will? Also I read somewhere that the floride filters may put aluminum into the clean water. Is that true?
      • Hi Becki -

        Yes, 2 filters is just as efficient as 4. Four just simply filters the water faster for you.

      • How long are the filters good for before replacements are needed?
      • Hi Sandy -

        The black berkeys are good for 6000 gallons per set of 2.

      • Do you find this question helpful?  Yes   No
    • From Jacqueline at 11/6/13 3:58 PM
      • If I am planning on filtering rain water is it better to have 4 filters or will 2 do the job?

      • Hi Jacqueline -

        2 will filter any type of water to the same degree as 4 black berkey filters. The difference when going with 4 is that the water will filter faster and 4 would be good for 12000 gallons as opposed to 6000 for 2.

      • Do you find this question helpful?  Yes   No
    • From Tim at 11/12/13 10:25 PM
      • can filters be replaced by purifiers later
      • Hi Tim -

        All the systems comes standard with the black berkey filters, which are water purifiers. If you are referencing the older while ceramic filters, then yes, the big berkey with the ceramic filters can be replaced with these newer black berkey filters.

      • Do you find this question helpful?  Yes   No
    • From CARL at 12/5/13 5:01 PM
      • What is the pH of the end product after filtration?
        What is the percentage of the water after filtration?
      • Hi Carl -

        The PH is dependent on the source water PH. The filters will remove acidic components from the water, and this will raise PH, but there is no guaranteed level. This is because all source water is different and the filters do not add anything to the water to achieve a specific level of alkalinity. I'm not sure what the second question is asking, but if you are referring to levels of contaminant removal, this can be found on the black berkey filters page, and in the helpful resources section.

      • Do you find this question helpful?  Yes   No
    • From melisa at 1/7/14 5:35 PM
      • Four questions:
        1) Our water has a plastic-y taste. will the berkey filter get rid of that?
        2) As I understand, the filters will filter out pond water, does that include manmade lakes? (I just wonder, in case of a true emergency/water shortage our local park has a big manmade lake) What about pool water?
        3) Is there a floor stand that is compatible with the big or royal berkey?
        4) As I understand, the chlorine filters have an aluminum component. Is there any amount of aluminum that leaches into the water?
      • Hi Melisa -

        1) It should remove this taste, but without us knowing exactly what this chemical is for sure, it's difficult for us to definitively answer this question.
        2) Yes, man-made lakes would be filterable also. Pools we do not recommend as they can contain other chemicals other than chlorine and without knowing what these are beforehand, we cannot make a generalization that all pool filter can be completely filtered and drinkable.
        3) We would recommend plant stands for this.
        4) There may be tiny amounts of alumina oxide which chemists and nutritionist have stated is inert and not absorbed by the body. For more details, please visit out PF-2 filter page.

    • From Dave at 2/7/14 10:55 AM
      • Will this filter out coliform bacteria?
      • Hi Dave -

        Yes, it will. But please be aware that coliform bacteria is only an indicator bacteria and is not necessarily dangerous and is why is not used for professional testing. Serious bacteria testing would be for dangerous forms such as e-coli, giardia, etc More in this article:

    • From Carie at 2/7/14 2:29 PM
      • I have just started looking into a water filtration system for my family after we have had multiple boil water orders and water main breaks and other water issues this winter. I am wondering about being able to take a water system along with us in our camper when we camp in order to filter water from the sink in the camper. We always hook up to running water at the campgrounds but don't always drink it since we are unsure of the safety from campground to campground.
      • Hi Carie -

        Yes, this is a common use of the Berkey systems, and would work well in that situation.

      • Do you find this question helpful?  Yes   No
    • From Barbara A W at 4/10/14 11:38 AM
      • How many of which type of filters are shipped with the Big Berkey - 2.1 gal?
      • Hi Barbara -

        The big berkey come standard with 2 black berkey filters. You'll see a drop down option available that will allow you to choose 4 black berkeys if desired. In addition, you'll see add-on options such as 2 or 4 PF-2 fluoride filters if desired.
