The Big Berkey® water filter is the perfect system for family of 4 people. Its filtration capacity can handle higher demands for pure water, such as when you have guests.

Simply pour water into the system's upper tank and easily dispense pure water using the lower tank's tap.

By adding 2 additional Black Berkey® filters to your Big Berkey®, you can filter approximately 26.5 liters of filtered water per hour.

The 2 Black Berkey™ filters included with your system can purify up to 22,700 liters of water. To calculate the lifespan of your Black Berkey® filters, check our FAQ.

The Big Berkey® system includes:

New: Quick priming kit
Stainless steel upper and lower chambers
2 Black Berkey® purification elements
1 stainless steel lid, knob, and screw
1 food-grade plastic spigot
2 wing nuts, 2 washers, 1 priming washer
2 blocking plugs
1 rubber seal for base
Downloadable instructions in English

*Flow rate is calculated with the upper tank full. The flow rate decreases as the water level drops.

    How do you assemble and use your Berkey® water purifier? ...

    Refer to the assembly document* for a diagram and precise instructions on how to assemble your stainless steel Berkey® water purifier.

    This documentation also contains instructions for setting up the filtration elements.

    For more details, you can refer to the specific document on priming the Black Berkey® elements*

    What is the most convenient way to fill the upper chamber of my Berkey® water purifier?

    Most people use a carafe or jug to pour water into the upper chamber. If you have a tap with a pull-out spray hose on your sink, this can also be a good solution.


    How do I clean my Berkey® water purifier?

    The upper chamber, which only temporarily holds water, will need to be cleaned less frequently than the lower chamber where water stagnates for longer periods. We recommend cleaning the lower chamber once a month.

    The stainless steel chambers can be cleaned with soapy water.

    In areas with hard water, lime deposits may accumulate on the spigots and chambers after prolonged use. To remove them, you can use pure vinegar or a 50-50% mixture of vinegar and water that you spray and let sit for about 15 minutes. Then wipe with a ScotchBrite pad or a soft brush, wash with soapy water, and rinse.


    There is still a little water in the chambers of my Berkey® water purifier. Is this normal?

    Yes, it is entirely normal for 1 to 2.5 cm of water to remain in the upper and lower chambers. For water to be filtered, it must pass through very fine micropores in the filters. The lower the water level in the upper chamber, the lower the pressure available to force the water through the micropores. You may have noticed that the filtration rate is much faster when the upper chamber is full than when it is half empty. This is because there is more pressure. The only way to remedy this would be to enlarge the pores of the filter elements, which would reduce the effectiveness of the Berkey purification system. During each cycle, the residual water from the previous cycle mixes with the water from the current cycle and is then purified. Therefore, there is no need to worry about the excess water during normal use. However, if you stop using your filter for an extended period, such as during a vacation, it is best to empty both chambers and let them dry completely.

    Regarding the lower chamber, the spigot cannot technically be positioned at the bottom of the tank for sealing reasons. Don't worry; this is not stagnant water as it will mix again and again during successive filtrations.


    How long can I keep and consume the water filtered by my Berkey® purifier?

    We recommend replacing your water filtered by your Berkey® system after three days if it has not been consumed. If the water is in a cold environment, this period can be extended to one week. This is a precautionary principle. The reason is that when you filter your water, the chemicals that inhibit bacterial growth are removed. In very humid environments, bacterial growth can occur more quickly.


    How do I transport my Berkey water purifier?

    If you need to transport your Berkey® filtration and purification system, you must first remove the Black Berkey® purification elements. If you do not remove them from the system, you risk breaking the stems. Place your water filters in a safe and sealed package. The upper and lower stainless steel parts fit into each other to facilitate transport and save space. If your system is equipped with a sight glass spigot, be sure to remove it or secure it so it does not break.

    Important: Failure to remove the filtration elements from the system may result in broken stems and will void the manufacturer's warranty.


    Can I use my Berkey® purification system with water from my softener?

    It all depends on the type of softener used. For example, CO2 or magnetic water softeners produce water that is normally fit for consumption (confirm with the manufacturer) and do not pose a problem with Berkey® systems.

    However, the most commonly used water softeners work with ion exchangers that convert calcium and magnesium, which are responsible for scale buildup, into sodium. The use of these softeners produces soft but salty water...

    The Black Berkey® water filters are designed to eliminate a large number of contaminants as stated in the test results conducted by an independent laboratory. However, they do not remove the minerals originally present in the water and conserve them for the benefit of our bodies. The residual sodium from softened water, present in high concentrations, will not be filtered by the Berkey® system and will end up in your drinking water. Unlike natural mineral salts, this sodium is highly concentrated and is obviously not desirable to consume.

    These synthetic salts can also clog the micropores of the filters, which will slow down or even stop the filtration. This could require very frequent maintenance of the filters.

    Therefore, for these systems, we do not recommend using softened water from a salt-based water softener to fill your Berkey® purifier.

    Note: Some installations are equipped with a by-pass to draw off the water before it passes through the softener. If this is the case, there is no problem using this water for your Berkey water purification systems


    Can I filter my rainwater/well water with Berkey® purifiers?

    Black Berkey® water filters used in Berkey® purification systems are entirely capable of filtering collected water.

    However, certain precautions are necessary. For instance, ensure that there is no contamination by a specific pollutant that might be absent from the test results conducted by Berkey®. Also, take care to limit the contact of animal feces (birds, squirrels, etc.) with your water or chemicals used on roofs. The water should be pre-filtered before being introduced into the purifier to avoid excessive suspended matter, which could quickly block the filters and they would need cleaned more often.

    Some of our customers have built rainwater filtration systems consisting of multi-stage capture processes (up to 5 stages in some systems) equipped with several Black Berkey® filter elements (from 4 to 8). The water is filtered in a number of stages and stored in adequate containers.

    Even though Black Berkey® elements are water purifiers, it is advisable, for this type of use, and if, for example, there is a risk of high contamination by E. coli, add a few drops of (unscented) chlorine-based disinfectant at the first stage of filtration.

    See this topic on filtering water from sources other than tap water.

Sous réserve de faire le test avec le liquide rouge. J'ai suivi les indications de montage très scrupuleusement, donc il ne devrait pas y avoir de problème.

La première fois, l’eau a un drôle de goût mais rassurez-vous après elle est délicieuse. J’ai enfin réussi à faire boire de l’eau du robinet à ma famille ! Et de bonne qualité ! Fini les bouteilles plastiques qui s’accumulent … merci !
