The Big Berkey is the most popular of all Berkey water filtration systems. It provides clean and pure water with no taste (as it’s supposed to) for up to 4 people.
When employing all 4 filter slots, the system’s maximum flow rate is approx. 7 gallons per hour – that means only when the upper chamber is filled to the top.
Because since Berkey systems rely on gravity to push the source water through their filter elements, the more water you pour inside, the higher the pressure and therefore flow rate is going to be.
The lower reservoir that collects the purified water can hold as much as 2.25 gallons.
What contaminants does the Big Berkey remove?
Examining the test results provided by New Millennium Concepts, ltd., the manufacturer of Berkey, it looks like their Black filter elements remove everything you can think of: From aluminum and heavy metals like lead to waterborne pathogens, chlorine, VOCs – you name it.
According to the company, the test results exceed NSF Standard 53 requirements.
If you also want to eliminate more than 97% fluoride and arsenic, consider purchasing the optional PF-2 post-filters.
The Big Berkey takes care of all of your cooking and drinking water needs having the perfect size for home use. It’s not too big to not fit on your countertop and still large enough to provide enough water for a whole family without long waiting times.
We also like its simple design that makes the system so easy to use. All you need to do is fill water into the top chamber and wait till it comes out at the bottom.
And in case you wonder, yes, all Berkey systems use the same filter elements. So if you ever want to upgrade (or downgrade) your unit, you can still use your old ones until they have reached their capacity to save money.
Speaking of money, 1 gallon of Berkey-purified drinking water costs almost nothing. This is because the filters have high capacities (about 3,000 gallons) and can last for years.
Only when you decide to use the additional fluoride elements will your costs increase slightly – still a lot cheaper than what you pay for bottled water.
What’s more, the Big Berkey will not remove any healthy minerals from your water (and thus not reduce TDS reading).
In addition, we like the stainless steel looks. 304 stainless steel also stands for longevity.
Another benefit is that Berkey systems do not run on electricity which again will save you money and is the best solution in a SHTF scenario. Plus you can use more or less any water source as your feed supply.
The Big Berkey does not require any plumbing to set up. In fact, assembling the unit does not even involve the use of tools. This allows you to stay flexible and move the system around wherever you want.
In case you miss clear directions, this is what you need to do:
Please note: Remember to wash your hands before proceeding.
Black Berkey elements require priming before use. Don’t worry, this sounds more complicated than it really is…
For PF-2 fluoride elements the priming (or purging) goes like this:
You may need to purge each element more than once in each direction.
In order to keep your Big Berkey in good shape, remember that you have to clean the filter elements from time to time. The frequency depends on your feed water quality and how much sediment and turbidity it contains. A good rule of thumb is about once a month or whenever you notice a significant drop in filtration speed.
To start the cleaning ritual, remove the elements and scrub them with a brush or scouring pad to rub off the outside layer that has absorbed all the impurities. This shouldn’t take more than a couple of minutes. When done, re-prime each filter before reinstalling.
Instead of a brush or scouring pad, you can also use a vegetable peeler and carefully peel away the outside layer under running water.
For reasons of hygiene, you might also want to wash out the lower chamber with soapy dishwater every once in a while. And if you live in an area with very hard water, the spigot might clog up so that you will have to remove it and soak it in vinegar to get off all the scale.
Like every other water filtration system the Big Berkey, too, has its drawbacks:
It’s not a surprised that the Big Berkey is the most sought after countertop water filtration system out there. It’s easy to assemble and use, low in maintenance, and very effective at removing impurities to provide drinking water of superb quality. That’s 4.5 stars from us!
