The world’s most powerful and economical water purification systems, Berkey® purifiers provide incredibly clean, pure water whether the source is a wild stream, stagnant pond, private well, or substandard municipal supply. Available in sizes large enough for the sustained needs of up to 325 people per system, Berkey purifiers rely on no moving parts and use no electricity.

Easy to use: Just fill the upper chamber with water. Gravity carries water through the Black Berkey purifying elements and incredibly pure water rains down into the Berkey’s lower chamber where it’s ready for you to use.

A recent national study found 316 different contaminants in U.S. drinking water. Berkey purifiers remove pathogenic bacteria, cysts and parasites while extracting chemicals including herbicides, pesticides, organic solvents, VOCs, detergents, cloudiness, silt, sediment, foul tastes and odors. They reduce heavy metals such as cadmium, chromium, copper, lead, mercury, aluminum as well as nitrites, without removing the beneficial minerals your body needs.

Berkey purifiers use proprietary micro-pore technology to achieve contaminant reduction of 99.99999%. This extreme level of purification, called “7-log” reduction, means that no more than one part per ten million of the original contaminant remains. This standard is 1000 times more stringent than what’s required to label a system as a simple “water filter.” Systems achieving 7-log reduction provide ultra-pure water not only in normal conditions, but also in circumstances of extreme and highly dangerous contamination. And unlike many purifiers, Black Berkey elements are cleanable: A Scotchbrite™ pad is all you need to remove exterior buildup and extend element life. Each element can clean up to 3000 gallons of water.

The media within Black Berkey® elements removes contaminants by a surface phenomenon called adsorption, the molecular attraction of substances to the surface of the media. The exclusive purification elements are also impregnated with proprietary media that promote ionic absorption of pollutants within the micro-porous elements. A key reason Berkey systems are so effective in removing contaminants from water is their long contact period. Most systems blast water through their filters at high pressure, which limits contact with their filter media to only a fraction of a second. Water molecules passing through the revolutionary micro-porous structure of the Black Berkey purification elements are drawn gently by gravity and remain in contact with the trapping media for several minutes. This multiplies the Black Berkey filter media’s ability to capture contaminants.

Clean water purified in Big Berkey

Berkey purifiers using the Black Berkey purification elements are proven to reduce pathogenic bacteria (including E. Coli, Klebsiella, Pseudomonas Aeruginosa, Giardia and Cryptosporidium) by 99.99999%. Berkey systems have been tested with the highest pathogenic contamination levels that can be produced in a laboratory. When contamination levels exceed a billion pathogens per liter of water (10,000 times the density of contamination used in the standard test protocol for bacteriological removal) they’re classified as TNTC (too numerous to count.) Under normal testing protocol, one pathogenic organism is tested at a time, each with a fresh purifying element. For this test, however, the laboratory was directed to combine three separate pathogenic TNTC cultures. Tested under this extreme contamination level, absolutely no pathogens were able to make it through the purification elements. The laboratory then incubated the water, and nothing grew. When the purified water was viewed under an electron microscope not even inviable microbes were detectable—nothing was present but pure water. Furthermore, contaminants including trihalomethanes, radon 222, and volatile organic compounds including benzene, 2,4-D, Heptachlor, MTBE, styrene, tetrachloroethylene and toulene, among many others, were reduced to below detectable limits.

Viruses: Far smaller than bacteria, viruses typically range upward in size from about 30 nanometers (nm). Black Berkey purification elements have been proven in Testing to reduce the MS2 and Fr Coliphage viruses, which are among the smallest viruses at about 25nm, to Log 5 (99.999%). No other gravity fed water filtration system even comes close to this performance.

The striking superiority of Berkey water purifiers can be demonstrated with food coloring. When bacteria are viewed under a powerful microscope, food coloring is often used as a contrast enhancer to make the bacteria easier to see. Food coloring consists of particles so small that even under magnification strong enough to show fine details in a single bacterium, the food coloring still appears only as uniform coloration. Yet Berkey purifiers effectively remove food coloring from water. Berkey systems are the only purifiers in the world that can do this.

Berkey purifiers are available in several configurations. All Berkey Systems using Black Berkey purifying elements meet or exceed the EPA’s stringent “7 Log” (99.99999%) contaminant reduction specification. Systems using Black Berkey elements within transparent Copolyester housings are known as Berkey Light Purifiers. Systems using Black Berkey elements within 304-grade stainless steel housings have the same purifying performance, and are known as Berkey Stainless Purifiers.

Note: Berkey purifiers aren’t yet available for shipment to Iowa, and some systems cannot be shipped to California. Unlike any other state in the union, Iowa doesn’t accept the results of any labs but their own, and their recurring annual lab fees are prohibitively inflated. The State of California, uniquely, says we can ship the stainless Travel Berkey into the state, but not the larger stainless systems. Californians also may order the Berkey Light system. Of course, any Berkey system may actually be used anywhere.

  1. Tara

    This product exceeded my expectations. Definitely give me a drinking water that didn’t make me gag. The water is crystal clear, no smell, clean sweet taste. This product is incredible!

  2. Sherrie Bowers

    I love my Big Berkey ever since I got it. I read the instructions carefully to make sure everything I do is right. I had my filters primed and the inside cleaned making sure that I can only taste nothing but pure, filtered water. There’s no trace of any metallic or plastic taste in the water and the end result from the unit to my glass is crystal clear. The stainless steel body has a nice polished texture that sits well in our counter and the flow rate is fairly fast which makes the unit dependable for safe drinking water daily.

  3. Alice

    Great investment! Sleek design, easy set up and great tasting water that will last for years.

  4. Nicole M.

    We really like the taste of the water. Fantastic product!

  5. Deborah

    One of the best decision I’ve made! This definitely filters all nasty taste and give you the cleanest water. My friend is using it and told me to buy it, worth every penny. You should get one of these item and start living healthy.

  6. Charley Dewalt

    I have now been using the Big Berkey for a year and a half, and I love it. It seems expensive up front, but I had tried Brita/Pur/Clear2O/refrigerator filtration and I hadn’t been impressed with any of them. Their filters were expensive and needed frequent replacement, and the water generally didn’t even taste very good. Since this Berkey package should last for years, according to my water usage math, I decided to go for it. I did purchase the glass sight spigot after a few weeks, and it’s much easier to see the water level in the tank, rather than having to pick up the top half and look down inside the Berkey. My taste tests between tap and filtered are definitely in favor of the Berkey. It just needs cleaning with soap and water once a month and I haven’t had any problems with gross water or rust. Is it my favorite chore? Absolutely not, but it’s totally worth the time to have clean and easy water filtration for the next month.

  7. Chantelle

    I was hesitant to purchase this item at first but my colleague recommended it. Since I have kids so I tried it and was very satisfied with the result. You can definitely taste the difference. Very easy to assemble. Highly recommended.

  8. Lillian G.

    I just bought this Berkey to give my Mom clean water through the Coronavirus craziness. Plant Based Pros is the only store who had it in stock and did they ever deliver! The Berkey arrived one week after I ordered it when all the other stores had 6+ week lead times. Now I can rest at night knowing that my Mom does not have to run to the store to get clean water. Thank you so much to Dee for guiding me through the purchase and delivering on your promises.

    We really like it. Water tastes great. We got it for the office and staff are going crazy over this.
