Frequently asked questions
The two Black Berkey Elements (BB9-2 Filters) in your Big Berkey can filter approximately 6,000 gallons of water before needing replacement. For an average family of four, this typically means replacing the filters every 2 to 3 years, depending on your water consumption and the quality of water being filtered.
Yes, the Big Berkey system can remove fluoride from your water, but you will need to purchase an additional set of PF-2 fluoride filters. These filters attach to the bottom of the Black Berkey Elements and together they efficiently remove fluoride and arsenic from your water.
Absolutely, the Big Berkey is highly effective at filtering well water, removing bacteria, viruses, and other contaminants common in well water sources. It's important to test your well water periodically to know which contaminants are present, as this can affect the lifespan of your filters.
The Big Berkey operates using a gravity-fed system. Water is poured into the upper chamber, where it gradually filters down through the Black Berkey Elements into the lower chamber, ready for use. This design eliminates the need for electricity, making the Big Berkey ideal for use in any situation, including emergencies or off-grid living.

The stainless steel design looks sleek on the counter, and even guests ask about it. It's a bit of an investment, but worth every penny.

My husband and I decided to purchase a water filter after the East Palestine, Ohio train derailment. We didn't want to go with the typical, mainstream brita water filter or the one that connects to a faucet. We have had those before and the filter has to be changed frequently. We liked that the Berkey filters out forever chemicals, specifically the chemicals spilled during the derailment. It also filters out over 200 contaminants, chemicals and bacteria. Setup was fairly easy, however priming the elements was challenging due to the adapter that fit onto our faucet which was a struggle. The life span of the filters is amazing, as they only need to be changed every 11,000 gallons. Although the filters are pricey, around $170ish for 2, they are worth it in the long run. Using the filter is easy. Once set up, just pour water in the top, put the lid back on and you're good to go. Quality of the materials is unmatched. We purchased a stand off Amazon that elevates the element, which you definitely need. Hoping to get the stainless steel spigot soon to replace the plastic one that came with the product. Lastly, I have to say the water tastes AMAZING. Like water should taste. It rivals the taste of Fiji, our preferred bottled water. Our family initially made fun of us for spending so much money on a water filter, but once they tasted it they plan on purchasing one. I was never a big water drinker before, but now I find myself drinking lots of it. We fill up multiple containers of it whenever we leave the house. Great product, give it a try!

Absolutely wonderful. Water taste so good

* Great for 7 months. * IMPORTANT: Prime filters (5 min water) for good flow. * Storage (was out of town) - Clean reservoir, let filters dry. Upon return, lazy didn't re-prime filters so REALLY slowed flow after storage. * Drank tap water because Berkey was so slow. Realized how BAD it tastes (had never notice before). * Re-priming fixed slow processing. * 2.5-gallon fills in ~30 minutes. * VERY pleased with performance. * Will track water use for 6,000-gallon filter life. * Amazon stand makes dispensing easier. * Expensive upfront cost BUT well worth it due to taste, convenience, low long

This works great. There isnβt even a hint of chlorine in the taste of the water. My only complaint is I canβt for the life of me understand why they are so expensive. They do the job but at a price.

After caving to the pressure of family and friends to order this water filter, I couldn't be more pleased with it and kicking myself for putting it off for too long. It's easy to assemble (be sure to really tighten the tap!), it fits on my kitchen counter well, and the water tastes exactly how clean, fresh water should taste. Being raised in a city with artesian well water, I got spoiled and have not been able to drink tap water in any other city I've lived in. No more lugging gallons of bottled water home every week or two, no more chemical tasting tap water. The only thing I'm second guessing is that I probably could have done just as well with a Travel Berkey rather than the Big Berkey, being a one-person household. Otherwise, I'm very pleased and would encourage ditching the environmentally irresponsible plastic bottles, questionable bottled water quality, and go for a unit that you can trust. In my case it will pay for itself in just over a year. The filters may be costly but they last a very long time. I won't need to replace them for many, many years. I definitely recommend Berkey water filtration systems.

The media could not be loaded. Major problem: Washers are industrial rubber and leaves a rubber smell and taste in the water. They should have been food grade silicone may be. Still don't know how to resolve that issue but I am not able to use the filter as it is because of this issue. Instructions could be much clearer than they were but we found some youtube videos to help. Mostly the unclear instructions were about priming using the priming pump (which we preferred) instead of the faucet method. If you are thinking of using the primer pump to prime the filter elements, we suggest you watch the video under the review section of the primer pump that we uploaded based on our initially struggled experience with it. That video shows how to solve the two problems with the primer pump. Two problems were: 1. It came with bare instructions without adequate diagram of the valve placements and it is easy to get it wrong without that. 2 The product isn't well designed because the tube insert on the input side is loose enough for air to get in ending up in priming pump not working well. After I struggled with it for 30-40 minutes, both these issues were thankfully solved by my husband so it worked really well and really fast. Two things he had to do: 1. Put a tourniquet like contraption on the input side of the "tube & valve overlap" to make the connection tight enough to not let air in so that the pump would work efficiently without sucking in extra air. 2. Keep the filter element COMPLETELY submerged under water to make it work without wasting time on pumping air in and out for a long time before water could come out. We thought we'll record it so other people could benefit from our experience. Please watch the video to know what I am talking about and make it easier on yourself to use the priming tool. We recorded 2 videos of different problematic parts but Amazon only lets us upload one video per review.
