2 Black Berkey® water filters kit for Berkey® water purifier

Of all the gravity filters that can be found on the market, Black Berkey® purification elements are the most effective. The micropores in Black Berkey® purification elements are so small that even pathogenic viruses and bacteria cannot get through them. Black Berkey® purification elements are so effective that they can even remove red food coloring from water without eliminating the good minerals your body needs. No other filtration element can succeed in doing so.

Contrary to some costly disposable filters, Black Berkey® purification elements not only have a very long lifespan,they can also be cleaned. When the flow decreases, simply wash the Black Berkey® purification elements with a ScotchBrite® pad under running water, reinstall them and your system is ready to purify water again.

As well as being washable, the filters will also self-sterilise, they are therefore protected when not in use. Do not hesitate to consult our FAQ for all your questions regarding maintenance and use.

With correct maintenance, each purification element will filter up to 11,350 liters and will provide pure, clean water for years (roughly ten years on average for a family of 4 people for 1.5 liters of drinking water per day).

To calculate the lifespan of Black Berkey® filters in detail, consult our FAQ.

Black Berkey® Purification Elements have been tested by accredited laboratories to exceed NSF/ANSI 53 Standards.

    What are Black Berkey ® water filters made of ?

    The composition of the Black Berkey® elements used in Berkey® water purifiers is a unique formulation protected by a patent. It is based on the mix of six different and specific types of media, which includes high-quality activated carbon. Compiled in a very compact matrix containing millions of microscopic pores, they create a "tortuous path" through which water can pass, but contaminants cannot. These channels are so thin that all undesirable elements are inevitably trapped. With a process of absorption and adsorption, submicron viruses are also blocked, something other water filters cannot do without the use of chemicals.

    The cylinder of activated carbon is impregnated with an ion-exchange resin. The activated carbon adsorbs or chemically binds to organic compounds, such as solvents and petroleum-based fuels, a large number of pesticides, and numerous pharmaceuticals. The ion-exchange resin eliminates many dissolved metals from the water by exchanging toxic heavy metals (like lead, mercury, and cadmium) for lighter and inoffensive metals (like sodium, the main component of table salt). All this enables a comprehensive and highly efficient filtration.

    Additionally, the manufacturer Berkey® New Millennium Concept Ltd. confirms that graphene oxide is not used in the composition of Black Berkey® filters.

    More details can be found on the page explaining the functioning of Berkey® water filters.

    Do Black Berkey® water filters contain silver?

    That's correct! Silver is used as an antimicrobial agent allowing each Black Berkey® element to self-sterilize. Analysis were conducted by an independent laboratory to guarantee that the silver used does not dissolve into the purified water, and this is precisely the case. The analysis concluded: "All control samples, including stock samples, positive and negative analytical controls, and the begative control collected prior to seeding yeilded appropriate results and were accepted. The results of the leaching control samples (effluent sample spiked with MS2 and R.nterrigena and analyzed at two time points) were quite similar, suggesting that no active antimicrobial agent is leaching into the treated water." 

    You can view the complete report results (in English).

    Is the base of the Black Berkey® water filter BPA-free?

    Yes, and it is the same for all Berkey products, including the Berkey® Light and
    Berkey® Sport. No BPA is present in any part.

    Is it true that the pH of water treated by Black Berkey® water filters increases?

    This is true, water that filters through the Black Berkey™ elements tends to be more basic than before being filtered. Its pH increases. And in reality, this is a good thing... Pathogenic bacteria and viruses thrive in acidic environments and struggle to survive in alkaline environments. The higher the pH, the greater the alkalinity.

    However, it is important to remember that the final pH level of the treated water can depend on other factors, like the pH level of the water before being filtered.

    Do Black Berkey® water filters remove micro-plastics?

    It is important to distinguish between plastics that dissolve in water and present a health risk and those that exist as miniscule solid particles.

    In the first group, among the plastics that are dangerous to health and can dissolve in water, the most widespread are Bisphenol A (BPA) and 1,1-Dichloroethane (11-DCA). We are pleased tp say, the Black Berkey™ filters can remove these two harmful plastics.

    Additionally, thanks to the filtration capability ranging from 24 to 26 nanometers, solid microplastics are also eliminated. These measure approximately 2.5 microns (2500 nanometers), which is significantly bigger than the 24 nanometers of the filter.

    How do Black Berkey® water filters remove viruses and bacteria?

    The micropores that constitute the Black Berkey™ filters are so fine that they stop microparticles such as viruses and bacteria from passing through. Even food colouring cannot pass through, and the filtered water becomes crystal clear!

    Viruses and bacteria are eventually trapped in these extremely fine "tortuous paths" (in the range of a few microns), where as the smaller water molecules (H2O) are not.

    This method efficiently distinguishes contaminants from purified water.

    For more details on filtration capacity, you can consult the complete test results.

    Do Black Berkey® filter elements act on glyphosate?

    Glyphosate is a herbicide and pesticide used in modern agriculture and primarily released into the environment via runoff water. Numerous analyses have proven that the molecule is everywhere and is found in the hair, blood, and urine of an increasingly large population.

    Its presence is also increasingly common in drinking water. The Black Berkey™ purification elements reduce glyphosate in your water by over 75%, exceeding the limits defined by laboratories.

    You can review the analysis results* concerning Black Berkey® water filters, and more specifically those related to pesticides*.

    Filtration of drug residues by Black Berkey® filters

    With the growing consumption of medicines, an increasing number of contaminants from pharmaceutical residues are being released into the natural environment and finish in tap water. Among these can be found endocrine disruptors such as Bisphenol A, anti-inflammatories such as naproxen, octylphenols, progesterone, hormonal treatments like HRT, and many more. Thankfully, the Black Berkey™ water filters have the capability to filter these substances, making your drinking water healthier.

    You can read the full analysis*  from tests conducted by independent laboratories.

    Do Black Berkey® water filters remove petroleum products?

    The Black Berkey™ filters have been tested to eliminate up to 99.9% of these petroleum-based contaminants:

    - Gasoline
    - Diesel
    - Crude oil
    - Kerosene
    - Refined oil

    Find the full laboratory results for Black Berkey® purification elements here.

    Can Black Berkey® water filters filter out chromium from water?

    Yes! The Black Berkey™ filtration elements have been tested to eliminate more than 99.8% of chromium 6, as this form is the most dangerous for humans (see page on the dangers of chromium 6).

    Chromium exists in different forms, some toxic and some not. For those interested, here are detailed explanations about chromium.

    In summary, chromium comes from two distinct sources: trivalent (chromium 3+) and hexavalent (chromium 6+).

    Trivalent chromium (C3) is a beneficial mineral for humans in trace quantities and is present in food.

    Hexavalent chromium (C6), however, is a toxic form resulting from industrial pollution: used in metal coatings (such as stainless steel), pigments and dyes, wood preservation products, and tanning processes.

    Not all filters are the same, and the removal of heavy metals does not necessarily mean that chromium 6 is eliminated. The Black Berkey™ filter is effective against this source of pollution as proven by these test results.

    Do Black Berkey® filters eliminate the parasites responsible for giardiasis and cryptosporidiosis?

    Giardiasis and cryptosporidiosis are both infections caused by protozoan parasites (giardia lamblia and cryptosporidium parvum) that affect the gastrointestinal tract. While giardiasis is often mild, cryptosporidiosis is a serious intestinal illness. These infections are commonly provoked from the ingestion of food or water or food contaminated with the feces of infected animals or humans.

    Diarrhea, gas, nausea, and cramps are common symptoms of giardiasis and cryptosporidiosis. The parasites are often found in outdoor water sources like lakes, streams, and swimming pools.

    The Black Berkey® filters eliminate over 99.996% of cryptosporidium and have been proven to decrease the amount of Giardia cysts by more than 99.994%, as confirmed by these test results.

    Can Black Berkey® water filters work against leptospirosis?

    Leptospirosisis caused by bacteria of the genus Leptospira. Considered as a serious infection, it is transmitted through the urine of infected animals, and is spread by the ingestion of contaminated water or food.

    Cases range from mild to severe with flu-like symptoms in milder cases, but some extreme cases with severe symptoms such as kindey damage or liver failure can be fatal.

    The Black Berkey™ purification elements have been proven to decrease the amount of Leptospira bacteria by over 99.6%, based on contamination levels far higher than those typically found in nature.

    Find more information on leptospirosis below.

    Read the test results proving the effectiveness of Black Berkey® filters against leptospirosis*.

    Do Black Berkey® water filters remove minerals?

    A number of minerals can be present in water in the form of dissolved ions, either negatively charged (anions) or positively charged (cations). These ionic forms are absorbable by the human body. Among these minerals are calcium (Ca++), carbonates (CO3--), bicarbonates (HCO3-), chlorides (Cl-), potassium (K+), magnesium (Mg++), sodium (Na+), nitrates (NO3-), and sulfates (SO4--).

    The media in the Black Berkey™ filters is not designed to eliminate these beneficial minerals (in their ionic forms) from the water. They may indeed be reduced if they are highly concentrated, but the majority will pass through the filters and be present in your filtered water.

    If you still wish to incorporate additional minerals to your water, we recommend liquid additives and adding them into the lower chamber of your Berkey® system to avoid reducing their concentration.

    Finally, we are frequently asked about the dry residue rate after filtration. The answer to this is easy: if you understand that the mineral concentration remains the same before and after filtration, the dry residue level also stays the same and entirely depends on the water you filter.

    Do Black Berkey® filters need to be primed before first use?

    Whether it's the Black Berkey™ filters or the Berkey® PF-2™ filters, it is necessary to prime them before their first use or after a long period of storage.

    You can refer to the Black Berkey® filter priming document and also the PF-2™ filter priming document (documents in English, provided in French at the time of purchase or upon request).

    To facilitate the priming of the Black Berkey® filters, and if the space under your faucet is limited, there is also a priming pump, which is very practical and allows you to prime the Black Berkey® filters anytime, anywhere.

    Fitting and priming Black Berkey® water filters

    The Black Berkey™ filters are standard equipment in Berkey® purification systems, the industry leader in gravity-fed water purifiers. Each filter is designed to purify approximately 11,300 liters of water before replacement. A pair of Black Berkey® filters in a Berkey® system will purify about 22,600 liters of water before we recommend replacing them. The Black Berkey® purification elements are sold in pairs and can be used to upgrade most gravity-fed water filter systems. They are washable and self-sterilizing and come with a proportional 2-year warranty.

    You can also find the installation and use instructions for the Black Berkey® purification elements* as well as the video explaining the priming of Black Berkey® water filters.

    To simplify the priming of Black Berkey® elements, Berkey® has created a priming pump. Check out the information regarding the Black Berkey Primer® pump.

    Black Berkey® Primer™ Pump Information

    The Black Berkey Primer™ is a manual pump that makes priming of Black Berkey™ filter elements easier without the need for tap pressure or when the space under the tap si too small for priming.

    Priming the Black Berkey® purification elements is essential to expel air and saturate the filters with water before use.

    The Primer™ pump also allows you to purge the Black Berkey® elements with air to clean the porous structure of the filter if necessary and to dry the filters for long-term storage (see information on storing Black Berkey® filters for details).

    The Primer pump therefore allows you to:

    1- Eliminate debris that can build up in the filter pores during use,
    2- Reduce the time that is necessary to dry the filters before storage,
    3- Facilitate the priming of the elements when water pressure is not accessible or when space under the tap is limited.
    4- Black Berkey® filters should never be primed with contaminated water. This is the case, for example, if you only have access to reclaimed water such as rainwater, borehole water, well water, etc. You must prime them with the Black Berkey® Primer pump. It is an essential tool in these conditions.

    The Black Berkey Primer™ is especially designed for use with Black Berkey® purification elements.

    Find here the Black Berkey Primer™ instructions for use To complement this information, you can watch a video on using the Black Berkey Primer™.

    Black Berkey® water filters are so effective that they can remove red food coloring from water. This is a foolproof way to test your system and ensure it is functioning correctly.

    The purpose of this test is to confirm that the system has been assembled correctly and that there are no internal leaks in your system. We recommend performing this test after the initial assembly of our systems, after removing or replacing Black Berkey® elements, or during the first use after drying and storing the elements for an extended period.

    The dye test is designed only for Black Berkey® purification elements. It should not be performed for the Sport Berkey® bottle or the PF-2 filters.

    The food coloring must be RED and LIQUID. Red food coloring (unlike other colors) does not contain minerals, so your filter will treat it as a contaminant and filter it out.

    You can find this food coloring in small bottles at specialty or arts and crafts stores. You must use a liquid coloring, not gel, and check its composition: it should not contain glucose, E330, or thickeners. The coloring should not be E120 Carmine (cochineal) or E162 Betanin (beetroot).

    Therefore, ensure that the food coloring used contains either E122 (carmoisine), E123 (amaranth), E124 (Ponceau), E127 (Erythrosine), E129 (Allura Red), or E180 (Rubine).
    Be aware that some red colorings also contain E102 (Tartrazine yellow) in their composition, which is also not suitable for the test.

    The red food coloring test should be performed after priming your Black Berkey® purification elements and WITHOUT THE PF-2 FILTERS™.


    - Start by removing all Berkey PF-2™ filters (if installed). If they remain in place, the warranty on these filters will no longer be valid.

    - Take only the upper chamber (with the Black Berkey® elements installed) and place it on containers (glasses, cups, vases...) of similar size so that there is a container under each filter. This will isolate any defective or leaking filters.

    - In a separate container filled with water, add the food coloring according to the proportions indicated below. Mix well. DO NOT pour the coloring directly into the tank.
    Prepare a mixture with the volume indicated below:

    COLORING DOSAGE for standard European brands
    3-5 drops of red food coloring per 4 liters of water.

    MCCORMICK COLORING DOSAGE recommended by Berkey®
    10 drops per 4 liters of water, as follows:
    - Travel Berkey® - 4 liters of water, 10 drops
    - Big Berkey® - 8 liters, 20 drops
    - Royal Berkey® - 8 liters, 20 drops
    - Imperial Berkey® - 8 liters, 20 drops
    - Crown Berkey® - 8 liters, 20 drops

    It is not necessary to completely fill the upper chamber for larger models, as long as the filters are fully submerged.

    - Let the water flow into the containers.

    If no red food coloring appears in any of your containers, your purification system is working correctly.

    If the water in any of the containers is red or has a pink tint, the filter in question is either defective, nearing the end of its life, or not sealed properly, allowing water to flow between the seal and the tank.


    - Are the nuts properly tightened? Do not use tools to tighten them. They should be hand-tightened for a perfect fit. Over-tightening the nuts could deform the threads, preventing a proper seal.

    - Have you used "red food coloring"? Red food coloring is the only type recommended for this test.

    - Is the washer on the stem properly placed inside the upper chamber with the nut fixed underneath? If the washer is outside the chamber with the nut, you will not have a proper seal, causing your system to malfunction. Place the washer inside the upper chamber and retest.

    - Are the blocking plugs properly sealing the unused holes (without filtering elements)? Are the plugs installed and tightened with a washer on each side? If the plugs are leaking, the test will fail. Tighten the plugs more firmly and retest.

    - If you are testing an element that has already failed, rinse and re-prime it. Retest.

    If, despite all these precautions, a filter fails the dye test, please contact customer service.
    When performing the test a second time, consider taking a video of your actions (mixing the dye, filling the upper tank, filtering into separate containers). Proof is required in case of a positive test and a claim.

    How should Black Berkey® water filters be cleaned and how often?

    The Black Berkey™ water filters do not necessarily need to be cleaned every time you clean your Berkey® water purifier. However, this depends on the quality of your water. If you live in an area where the water is significantly dirtier than usual, more frequent cleaning of the elements may be necessary to remove debris that can clog the pores of your Black Berkey® purification elements.

    Regarding the frequency of cleaning the filters, it can be estimated that it is necessary when you notice that the flow rate starts to decrease significantly. For hard water, cleaning should be done every month. In other cases, set a maximum limit of 4 to 5 months to avoid reaching the point where the filters are completely clogged.

    How to clean your filters?

    1. Start by emptying and disassembling the Black Berkey® purification elements from the Berkey® system. Use a cleaning pad similar to a Scotch Brite pad (abrasive side) and scrub the exterior of the Black Berkey® purification elements under running (cold) water.
    2. Reprime the filters.
    3. Reassemble the Black Berkey® purification elements in your Berkey® system and proceed with a new filtration by filling the upper chamber.

    How long do Black Berkey® water filters last?

    Each Black Berkey® water filter is designed to filter and purify approximately 11,350 liters of water before needing replacement. The pair of elements that equips all Berkey® systems (except the Go Berkey®, which has only one) will filter and purify about 22,700 liters of water before needing to be changed.

    This equates to about 10 years of use for two Black Berkey® filters in a system serving a family of four, each consuming 1.5 liters of water per day.

    Example calculation to determine when to change the filters in a Big Berkey® system:

    The Big Berkey® has a capacity of 8.5 liters. If the system is fully filled once a day, the calculation will be as follows: 22700 / 8.5 / 365 = 7.3 years

    This formula can be adjusted according to your model and daily filling habits to determine how often you will need to change your filters.

    Important note: The theoretical lifespan may vary depending on the water you filter. Not all water is equally loaded with contaminants. Therefore, this theoretical lifespan is not universal and depends entirely on the composition of each type of water and the maintenance given to the filters.

    You can also apply this formula to PF-2 filters based on their theoretical filtration capacity of 3,800 liters.

    How should Black Berkey® water filters be stored and for how long?

    1- If you have already used your filters

    The storage method will vary based on the duration for which the Black Berkey® water filters will be out of use:

    - If the period of non-use is less than 3 days, no special action is required.

    - If the period of non-use is more than 3 days and less than 15 days and you want to avoid the re-priming process, remove them from the system, place them in a sealed plastic bag, and store the filters in the refrigerator, ensuring that they do not freeze. This will keep the filters saturated with water and avoid re-priming. If you find that they are filtering more slowly than usual when you put them back into use, re-prime them until water droplets form on the outside of the filter walls.

    - For longer-term storage, we recommend drying and sealing the filters. The most important thing is to ensure they are completely dry before storing them to prevent bacterial growth. One way to dry your filters out completely is to leave them on a windowsill for one to three days. We also offer a priming and purging device called the Black Berkey Primer™. The advantage of purging the Black Berkey® purification elements is that they dry very quickly. When the filters are dry, place them in a tightly sealed plastic bag. Black Berkey® filters are extremely powerful and can absorb odors and smoke in the air. When you are ready to use them again, clean them by scrubbing the exterior with a Scotch-Brite® pad or a stiff brush. Then re-prime the filters manually or with the Black Berkey Primer™ before placing them back in the system.

    ** Please note that the above storage methods apply only to Black Berkey® purification elements. See below for PF-2 filters.

    2- If you have never used your filters

    If the filters are unopened and still in their original packaging, be careful not to store them in an place with strong odors, such as a laundry room or garage. The elements contain activated carbon, which allows them to absorb odors from the storage area. Avoid storing them near highly scented items such as soap or laundry detergent.

    In theory, the shelf life of Black Berkey® purification elements is limitless.

    When storing the stainless steel tanks of your Berkey® system, it is best to empty them completely, as stagnant water can harbor bacteria. We recommend washing your Berkey® system with soapy water before allowing to dry.

    Why shouldn't Berkey® water filters be allowed to freeze?

    It is strongly advised against letting your filters freeze. Similarly, it is strictly discouraged to store the elements (even unused ones) in very cold climates. Residual water inside the element will expand and consequently enlarge the pore size, eventually destroying the element. Whether your filters are unused or already used and completely dried, a small amount of moisture could still remain inside, especially in predominantly humid climates. This moisture could expand inside the filter and render it unusable. Please note that this recommendation applies to ALL Berkey® elements, including the Sport Berkey® bottle. Freezing your element and making it unusable will also void your warranty coverage.

    What should I do if the flow from my Berkey® water purifier becomes very slow?

    Two scenarios are possible:

    1- If you have just acquired your Berkey® water purifier and the filters are new, the problem is usually due to high water tension. This prevents air from being purged from the micropores of your Black Berkey® water filters. Your filtration elements must be purged of this air to allow water to pass through them. A beige priming washer/blue valve and priming instructions are provided with the Black Berkey™ elements. Remove your filters, prime them, then reinstall them in your Berkey®. This should resolve the slow flow rate issue.

    2- If the flow rate slows considerably during the use of your Berkey® system, the problem can usually be resolved by cleaning the elements. Turbidity and clogging of the micropores by sediment are usually the cause of this issue. Just remove the elements from your system and scrub the exterior of each element with the abrasive side of a ScotchBrite® sponge. Scrub a section of the element until you see some black on the sponge, then move to another section until you have scrubbed around each element. This process should only take a few minutes and should only be done under running water. Re-prime each element, then reinstall them in tank. Your flow rate should be back to normal.

    CAUTION: Never use soap, vinegar, detergent, or any other cleaning product.

    Black Berkey® water filters are fine enough to remove viruses. Does this mean that they clog up easily and more frequently?

    The exclusive design of the Black Berkey® filtration and purification elements compensates for the amazingly small pore size by using an exponentially greater number of micropores in each element. It is for this reason that Black Berkey® water filters produce about 8 times more water per hour than other rival elements. Even though some surface pores may become clogged by contaminants, it is very difficult to clog all the pores and therefore block the filter completely. Towards the end, you may see a slowdown in the filtration rate, but never a total blockage. If this occurs, the filter can be cleaned by simply scrubbing the exterior of the element with a ScotchBrite® pad or a toothbrush. This will remove the particles clogging the surface pores of the filter.

    In conclusion, even though the filters have very fine micropores, the filter will not block prematurely.

    Can I use my Black Berkey® water filters after 11,300 litres of use?

    The filtration capacity of Black Berkey® purification elements is defined by their effectiveness in reducing heavy metals. After filtering this volume of water, it is possible that some of these heavy metals may pass through the filter. Nevertheless, their effectiveness on other pollutants remains intact well beyond the 11,300 liters.

    Nonetheless, for safety, it is best to stick to this theoretical capacity and change the filters once this volume of water is has been filtered.

    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

    What is the composition of the washers used with Black Berkey® water filters?

    The washers are made of food-grade neoprene rubber. Additionally, no components used in Berkey® systems contain any harmful substances. For example, there is no trace of BPA in Berkey® products.

    Regarding the washers, keep in mind that they never come into contact with the filtered or purified water.

    Can I filter my pool water with Black Berkey™ filters and drink it?

    The World Health Organization states that the below sources are not advisable to use as drinking water:

    - Water from radiator circuits, hot water tanks (domestic heating systems)
    - Water from toilet bowls or flush tanks
    - Water from in waterbeds
    - Water from swimming pools and spas

    The chemicals and contaminants often found in swimming pools are many and most are toxic: pH+, pH-, alkalinity adjustment (bicarbonate of soda, muriatic acid, sodium bisulfate), calcium hardness increase, chlorine, bromine, biguanide, cyanuric acid, ammonia, bacteria and other pathogens, algae, insects, and animal waste...

    The presence and levels of these chemical contaminants depend on numerous factors, including the type of pool, the type of disinfectants used and their dosage, the bather load, temperature, and pH.

    Although Black Berkey® filters have been rigorously tested by independent third-party laboratories for the removal or reduction of numerous contaminants (herbicides, heavy metals, chlorine, chloramine, pathogenic bacteria, parasites, pesticides, perfluorinated acid compounds, petroleum products, pharmaceuticals, radiological products, trihalomethanes, viruses, and volatile organic compounds...) and even though the test data shows that chlorine concentration decreases by more than 99.9%, it is not recommended to filter water from your pool with Berkey® systems for frequent consumption.

    This water could contain contaminants or chemicals other than those tested, for which there is no factual data regarding their safety.

    Do Black Berkey® filters remove limescale?

    Limestone is actually a form of calcium called calcium carbonate. Not only is it rich in calcium but also in dissolved magnesium (essential minerals for health). Calcium is naturally present in water. It enters into the water when it passes through the soil before being pumped and made drinkable. Limestone is a natural element, and tap water can provide up to 25% of the daily calcium intake. So why would you want to eliminate it?

    Well, Berkey® filters do not eliminate it! The mineral salts remain present in the filtered water for your well-being, unlike pollutants which are removed.

    However, if deposits build up in the tanks due to very hard water, it is best to occasionally clean them with white vinegar and warm water, for example. As for the filters, they can, according to recommendations, be scrubbed on the outside with a soft brush or a Scotch-Brite® sponge to clean them and remove any blocked pores.

    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.

    L'eau de ma première filtration a un goût particulier, est-ce normal ?

    Si les filtres n'ont pas été nettoyés et amorcés correctement ou encore si vos cuves n'ont pas été parfaitement nettoyées et rincées, l'eau de vos premières filtrations peut avoir alors un goût particulier, voire minéral. Vous pouvez vider les 2/3 premières filtrations.

    SI cela persiste, assurez vous que les joints noirs des filtres Black Berkey® sont bien positionnés côté cuve supérieure et non au-dessus des écrous papillons, côté cuve inférieure.

    Le cas échéant, procéder à nouveau à un nettoyage et amorçage plus rigoureux de votre système,

    My filtration is very fast, is this normal?

    Congratulations! This indicates your Black Berkey© filters have been perfectly primed!

    The water gently trrickles through as soon as you fill the upper chamber. It is the weight of the water column that forcefully pushes the water through the filters. Once the water column decreases (between the last third and the halfway point), the water drips quickly.

    What makes the Black Berkey® filters strong and efficient are the microchannels that take a tortuous path, allowing the water to contact the filter over a long distance. But since there are millions of these microchannels, in the end the water filtered very quickly.

    Generally, a full chamber is filtered in 45 minutes, give or take 10 minutes. If this is not the case, it means your filters are not properly primed. You should then re-prime them according to the instructions provided in your manual.

    If you find that the filtration is very fast (10 to 20 minutes), again, don’t worry! The filtration speed indicated by the manufacturer is an average, and very fast filtration does not indicate that your filters are not working. First, check that your black seals are properly installed in the upper chamber and that the blocking plugs are securely in place and tight (except for the Travel model). Also, make sure the wing nuts are sufficiently tightened (without over-tightening). After that, when the water is being filtered, check by lifting the upper chamber that the water flows only through the ends of the Black Berkey® filter stems. Finally, if after all these checks the filtration is still very fast, you can perform a red dye test following the instructions in your manuals or in our FAQ. This is the final step that will find out if your filters are working properly or not.

    Do Black Berkey® filter graphene?

    The question has been frequently asked over the past few months. First and foremost, it is important to have informed and factual information on the subject. If you are asking this question, you have probably read alarming articles on the topic. We invite you to read this article from AFP to help balance the information.

    The manufacturer, Berkey® New Millennium Concept Ltd., confirms that graphene oxide is not used in the composition of Black Berkey® filters.

    Furthermore, if the water to be filtered contained this component, NMCL does not have tests to verify its reduction by the Black Berkey® elements. Without test results, we cannot determine if the elements are capable of reducing or removing it.

    It should be noted, however, that the filtration fineness of Black Berkey® elements is about 22-24 nanometers. Any molecule larger than this measurement is mechanically trapped and thus retained by the filters.
