Clearance: Big Berkey Purifier System, Standard

This is an R1 clearance item. Please check the tables below to see how we rate our clearance items.

Water being dispensed from Berkey purifierThe 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.

  • “The Berkey water filter is a quality system, well made. I used a pitcher system before but the water now is amazing! It’s also very attractive sitting on the kitchen counter. Thanks for a quality product and, as always, excellent customer service.”

    – Diana Beardsley, TX

Clean water purified in Big BerkeyBerkey 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 independent 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.

  • “The best water you can get from a filter. Well worth the investment!”

    – Robin H., CA

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. More details of these regulatory novelties can be seen here.

Pond water, dirty and purified in Berkey systemTotal Virus Control: Black Berkey® filtration systems are an integral part of the ideal solution for treating virus-contaminated water supplies. The accepted standard for using chlorine to kill waterborne viruses is 2 PPM (2 parts of chlorine per 1 million parts of water.) 2 PPM is achieved by adding 8 drops of straight chlorine (common chlorine bleach) to 1 gallon of water. For "good measure" the recommendation is often made to use up to 16 drops per gallon. But who wants to consume all of that chlorine? Berkey® Purifiers solve this dilemma. Black Berkey® elements remove the chlorine from the treated water after the chlorine has completely killed any viruses present. You're left with only what you want... ultra pure, ultra safe, great tasting water!

The Black Berkey filter formulation has been tested by state & EPA accredited laboratories. Click to see some of those test results, from Spectrum Labs and the University of Arizona.

Bottom Line: If you’re a highly detail-oriented person, we recommend sticking to “R1.” But after a week’s use, the only real difference between one of these items and a brand new one will be the money you saved.

Expanded Ratings Descriptions

R1 Very close scrutiny is required to tell that the item isn’t brand new. Working surfaces may show slight wear; for example, the bottom-inside of a Bosch mixer bowl may show swirl marks because Bosch mixer whips are designed to “float” against bottom of bowl. Non-working surfaces (cabinet, control panel) look essentially new. Carton may not be perfect.
R2 Typically has a small scuff or mark on a non-working surface like a mixer cabinet or the top of a pressure cooker lid.
FR Mostly returned items which have been brought fully up to new-equipment performance specs at the factory.
D Demonstration items have been operated briefly at Pleasant Hill Grain.
DIS These items have never been used but we no longer sell them at full price in our store because it was discontinued by us or by the manufacturer.
U Has had light use.
SDB Has moderate damage or blemish on a non-working surface, such as a scratch or dent in the housing, or paint blemish.
NOS A brand new item that isn't the newest model.

    I've been looking to buy a Berkey Water Filter for years, and it has not let me down. I enjoy not smelling my water! I have to mention Pleasant Hill Grain's customer service, they were awesome when I called on a Saturday morning with a couple issues I had, they were great! I wouldn't ever hesitate ordering from Pleasant Hill again, and will... need more filters for my Berkey : )

  • Most valuable possession in my suitcase!
    By on - Verified Buyer
    For the past ten years, I have been traveling throughout South America, living the expat lifestyle. It's been wonderful! What is the one thing I would NEVER FORGET to pack in my luggage? My Berkey Water Filter! You never know when your water source may be unreliable and that includes those of you who use the same tap water every day! But wherever my travels took me, I knew I could drink any water that had been purified by my Berkey. And when I left Ecuador in March to return to the US? Yep, I was able to sell my Berkey to another gringo down there for exactly the same price for which I'd paid for it originally. That's how well-known and respected the Berkey brand is, throughout the world! So go ahead and buy with confidence in the product and its value maintaining over time. The folks at Pleasant Hill are my only source for obtaining anything Berkey. They are the best, too!

    I became concerned about the chlorine in our city water, so began my mission to find a way to filter our water without a whole house system which could be costly. We're happy we found the Berkey water purifier and recommend it to anyone wanting to improve their drinking water.

  • Very pleased!
    By on - Verified Buyer
    I purchased three of the Big Berkies for my family. My son and daughter are absolutely in love with the quality of the water and the convenience of having that water right at their finger tips. My husband and I drink nothing else but Berky water, it's just so convenient for us. Thank you so much for making these available online with super fast shipping.

    We've been very pleased with our Berkey purifier. It's great to know that we're drinking pure, uncontaminated water every day. We plan to take it on our 3 week long cross-country trip!

    Three weeks, that's a big trip! Stop in if you come by Hampton, Nebraska and see us Shauna! We're just off I-80.
