I've owned a Berkey water filter for years, and I'm a big fan.

Earlier, I wrote The Berkey Water Filter Ultimate Buyer's Guide covering all six models and how to choose the right one. But since the Big Berkey is the most popular one, I thought it should get its own review.

 1. Who makes Big Berkey?

It's manufactured by New Millennium Concepts, Ltd. in Arlington, Texas.

 2. Where is it made?

The black Berkey filters are made in the USA. The stainless steel housings are assembled from US parts and imported parts. None of the parts are made in China.

 3. How does a Berkey filter work?

Gravity feeds the water through the system. The black filters have microscopic pores that absorb the water while blocking pollutants.

 4. How do you use a Berkey filter?

All you have to do it take off the lid and fill the upper chamber with water. The water drips down to the lower chamber and you dispense it through a spigot.

 5. What contaminants does Big Berkey remove?

It filters out sediment and rust as well as all kinds of organic and inorganic contaminants like bacteria and viruses, parasites, cysts, heavy metals, and chemicals. It also eliminates bad tastes and smells

See my article Quick Guide to Berkey Water Filter Contaminant Removal for an easy to understand infographic about the kinds of contaminants the Berkey can filter out. 

 6. Does Big Berkey take out chlorine?

Yes. No more water that smells like bleach!

 7. Does Big Berkey filter out fluoride?

Yes and no. The black Berkey filters don't remove fluoride, but you can add the optional PF-2 fluoride and arsenic filters. They will take care of the fluoride.

 8. Will it remove sulfur and iron from well water?

It will reduce sulfur and iron quite a bit,  but it won't remove them completely. The taste and smell will be noticeably better, though.

 9. Does Big Berkey leave in the healthy minerals?

Yes. It leaves the good minerals alone.

10. Does a Berkey filter increase alkalinity?

Yes, it does raise it a little because it eliminates contaminants that tend to make water more acidic. Several factors play into the pH level of the filtered water, including the pH of the prefiltered water.

11. How many filters does it have?

It comes with 2 black Berkey filter elements, but it can hold up to 4. You can also add up to 4 PF-2 fluoride and arsenic filters.

12. How many gallons does the Big Berkey hold?

Big Berkey has a total capacity of 2.25 gallons.

13. How many people is the Big Berkey good for?

It's recommended for groups of 1 - 4 people.

14. How long does it take for Big Berkey to filter water?

If it has 2 black Berkey filters and if the upper chamber is filled to the top, it can theoretically filter 3.5 gallons per hour. However, as the water level in the top goes down, the flow rate also decreases.

15. What are its dimensions?

When assembled, it's 19" tall, and it has a diameter of 8.5".

16. How do you assemble a Berkey filter system?

It's very simple.

First you prime the filters.

Then you place the black filters in the upper chamber and secure them with the provided wingnuts and washers. The optional fluoride filters screw right on to them.

You also attach the spigot to the lower chamber.

Place the top chamber on the lower one, and you're good to go.

17. How do you prime the Berkey filters?

You do this by flushing them with water from kitchen faucet. Warning: Prepare to get wet! I've never succeeded at priming the filters without spraying water all over myself and the kitchen. This is the only gripe I have with Berkey.

NEWS FLASH! 

Black Berkey Primer

Berkey has introduced a new hand pump to make the job much easier and to keep you dry. You don't have to be at the kitchen sink to prime the filters, either. You just need to have a container of water to put the filter in when you prime it.

The pump is made for the black filters only. It won't work with the optional fluoride filters. ​

So do yourself a favor and get yourself a Black Berkey Pump to go along with the filters. It's available at Amazon.​

18. How long do Berkey filters last?

It depends on your usage. Each black filter has a life of 3,000 gallons. That means that if you have 2 filters and use 3 gallons a day, they will last over 5 years.

A pair of fluoride filters should be replaced every 1,000 gallons. At 3 gallons a day that's about once every 11 months.

When you calculate the cost per gallon based on the price of the replacement filters, you get a cost of about 2¢ per gallon of filtered water with the Black Berkey filters only.

But what if you want to add on the PF-2 fluoride/arsenic filters?

The addition of the fluoride/arsenic filters increases the cost to 7¢ per gallon.

19. How do you clean a Berkey system?

When the black Berkey filters need a cleaning, you just scrub them with plain water and one of those scratchy green scrubbing pads.

You can clean the container with some mild soap and water or diluted white vinegar.

20. Can the Big Berkey be used to filter river water in the event of a disaster?

Yes it can! Rivers, ponds, lakes - almost any kind of water can be used. This is really great for people who want to be prepared for emergencies.

21. Can a Berkey filter ocean water?

No. It doesn't desalinate. If you put salt water into it you will ruin the filters.

22. Does it soften hard water?

No, it doesn't. Hard water results from minerals in the water. Berkey doesn't remove healthy minerals, so if you put hard water in, it's going to stay hard. 

23. Would it make Flint, Michigan water safe to drink?

Flint, Michigan water

I love this question because it's the essence of everything we want to know when we're looking for a water filter. The answer is yes. You can even put tap water from Flint, Michigan through the Big Berkey and be confident that what comes out is clean pure safe-to-drink water.

24. What warranty does Berkey have?

The manufacturer warranty is 12 months on the systems and PF-2 fluoride/arsenic filters and 2 years on black Berkey filters.

25. Where can I get the best price on a Big Berkey?

There are several places online where you can buy the Big Berkey, including Amazon. All of the ones I checked out are selling it for the same price and have free shipping.

Except for the manufacturer, that is. It costs slightly more there and they only have free shipping if you spend $750 or more.

Another option to consider is an authorized Berkey distributor called Berkey Filters. The base system is the same price as Amazon, but they have special offers on accessories and add-ons at the time of purchase. Sometimes you can find some great deals on scratch and dent items, too.
