Product Description

Product Description

INCLUDES: Big Berkey stainless steel housing (Upper, Lower & Lid), 2 Black Berkey Filters, 2 Fluoride Elements, 2 Hole Plugs, 1 knob, 1 easy flow spigot, and 1 set of easy to follow assembly instructions. When drinking water that’s been filtered using a Berkey purifier, you can rest assured that your water is clean and safe for consumption. In fact, Black Berkey purifier elements are far more powerful compared to competitors’ water filters. When tested Berkey water filter elements removed 100% of pathogens, allowing them to be classified as purifiers rather than simply filters. The included two (white) Berkey fluoride filters attach to the bottom of the Berkey Purifiers and hang in the lower chamber. Berkey fluoride filters reduce the amount of fluoride in your water UP TO 95%. Each Fluoride filter has a lifespan of 1,000 gallons and each purifier can filter up to 3,000 gallons. The Big Berkey is constructed from High Grade 304 Stainless Steel, and can accommodate up to four Berkey Purification elements and four Fluoride filters, however only two of each are included with this package.

From the Manufacturer

The versatile Big Berkey system is the ideal system for use at home with small or medium sized families, travel, outdoor activities or during unexpected emergencies. This powerful system purifies both treated water and untreated raw water from such sources as remote lakes, streams, stagnant ponds and water supplies in foreign countries, where regulations may be substandard at best. Perfect for everyday use, outdoor activities and a must in hostile environments where electricity, water pressure or treated water may not be available. The Big Berkey system removes pathogenic bacteria, cysts and parasites entirely and extracts harmful chemicals such as herbicides, pesticides, VOCs, organic solvents, radon 222 and trihalomethanes. It also reduces nitrates, nitrites and unhealthy minerals such as lead and mercury. This system is so powerful it can remove food coloring from water without removing the beneficial minerals your body needs. Virtually no other system can duplicate this performance. Constructed of highly polished 304 stainless steel, the system comes complete with four purification elements and utilizes the latest technological advances. This system has a storage capacity of about 2.25 gallons (8.5 liters) and when in use it stands 19.25" in height with a diameter of 8.5". The upper chamber nests within the lower chamber for transport and stands only 13" in height. Configured with four Black Berkey purification elements the system will purify up to 7 Gallons (13.3 liters) per hour.

5.0 out of 5 stars IMPORTANT UPDATE TO The key to successful installation and use of a Berkey water filter: their site
By grt0106 on October 23, 2021
We sound the perfect solution to the problem we mentioned at the end of our previous post.

As a result of spending many hours searching Amazon's website, we found the PERFECT solution for performing the Red Dye Test with a Big Berkey Stainless Steel Filter: a two-gallon, heavy-duty glass container, with a lid diameter of 7.75 inches. THIS DIAMETER ALLOWS USERS TO SECURELY MOUNT THEIR BIG BERKEY ON TOP OF THE JAR TO VIEW THE OUTPUT OF AS MANY AS FOUR BLACK FILTERS SIMULTANEOUSLY. It's the "Anchor Hocking 69372MN 2 Gallon Glass Heritage Jar" (see photo), Amazon item B014AVB3KU, currently priced at $41.99.

OUR PREVIOUS POST BEGINS WITH THE NEXT PARAGRAPH

Because the vendor of the distilled water that we have been drinking for decades has recently been selling out frequently, we decided that the time has come for a backup supply that makes use of our tap water. Before we decided on the Big Berkey, we read not only all the comments here on Amazon but also everything that is available on the Berkey website.

On the Berkey website, multiple texts and videos discuss everything a potential purchaser needs to know, including:

-Descriptions of all six sizes ranging from 1.50 gallons to 6.00 gallons

-Berkey's recommended minimum and maximum number of users for each size

-Berkey Quick Start guide

-Priming Black Berkey Filters

-Priming White Fluoride Filters

-Cleaning the Black Berkey filters

-Routine System Maintenance

-Testing Black Berkey Filters

-Instructional Manuals

-Parts & Accessories

The site also offers a Water Quality Search link: enter your ZIP Code to learn how your local water supply stacks up in terms of the standards of the Environmental Working Group (EWG), which are more stringent than the federal standards (which reportedly haven't been updated for more than 20 years).

According to the most recent data (2015-2017) available for the provider of our tap water, here are Berkey's findings:

Of the 21 Total Contaminants, 8 exceed EWG guidelines, including:

-519.8X Arsenic: Berkey removes more than 99.9%

-188.9X Total trihalomethanes (TTHMs): Berkey removes more than 99.80%

-105.2X Haloacetic acids (HAAS): Berkey removes more than 98.0%

-7.0X Uranium: Berkey removes 98.7%

Of the 21 total contaminants 14 are reduced or removed by Berkey; for example, a Berkey that is equipped with the white Fluoride filters removes up to 97%

Berkey's Detailed Data ReOur Local Water Supply

The site provides links to all the following data:

-The contaminants that exceed the EWG guidelines

-The contaminants that meet the EWG guidelines

-The contaminants that Berkey Removes

-The contaminants that Berkey does not remove or that were untested

In addition to all the above information, the site offers much more; enough to merit many hours of perusal.

In our case, because we wanted our very first attempt at installation to be successful, we unboxed our Big Berkey only ONTHE DAY AFTER spending most of one day exploring the website. The result was an uneventful installation, including running the Red Dye Test and attaching the two White Fluoride Filters to our two Black Berkey Filters.

As suggested in Berkey's literature, we filled the top chamber to the brim with tap water the night before we intended to taste the output.

Conclusion #1: re the Berkey's output: In comparison with the distilled water that we have been drinking for many years, we are unable to appreciate any significant difference in either the smell or the taste. (We have never tried the tap water directly, so we are unable to compare with the output of the Berkey.)

TEST RESULTS:

pH

-Tap water 7.4 (neutral)

-Distilled water 6.4 (slightly acidic)

-Berkey water 9 (slightly alkaline)

Total Dissolved Solids (TDS), ppm

-Tap Water 0270

-Distilled water 0002

-Berkey Water 0250

INTERPRETATION OF RESULTS

According to Berkey,

TDS Metering

"A TDS meter cannot identify between; healthy ionic minerals, harmful sedimentary minerals, and heavy metals. In other words, TDS is not a good way to measure the 'cleanliness' of water because beneficial minerals are also considered total dissolved solids.

"It is our belief at Berkey Filters, that a water purification system should filter out things that are harmful to your body, but leave in the helpful things such as beneficial minerals. The Black Berkey elements, utilized in all our Berkey Systems, are designed, to do exactly that! The Berkey Black filter’s proprietary design allows healthful beneficial minerals (like calcium, potassium, etc.) to remain in your water and remove: chemicals, harmful sedimentary minerals, heavy metals and many other contaminants (200+ in total) see Our Independent Test results!"

(Clicking on the Independent Test link leads to a data-filled page entitled, "Black Berkey Filter Specifications" that is sub-titled, "Take an in-depth look at the test results."

Re the Increased Alkalinity (Berkey output pH 9 in comparison with the neutral pH 7.4 of Water Directly from the Tap

According to the Berkey website, the following are some of the benefits of the slight increase in alkalinity of our tap water because of the Berkey:

"Alkaline water is slightly more 'sweet' than pure water. In other words, it has a higher pH. While pure water has a neutral pH of 7, alkaline drinking water has a pH between 8 and 9.

"The data is mixed on the health benefits of alkaline water, but several studies have found that it helps with acid reflux, high blood pressure, high cholesterol and diabetes. More research is still needed to support the benefits, but when it comes to filtering normal water, more alkalinity isn’t a bad thing.

"As noted previously, pollutants can increase the acidity in the water and if you use a filter like the Black Berkey filter to filter your drinking water, it will filter out those contaminants and raise the alkalinity, providing clean drinking water."

Conclusion #2: The fact that the Berkey reduced the ppm of the tap water from 270 to 250 while increasing the pH confirms the Berkey statement that the filter is removing contaminants which increase the acidity of the water.

UNDERSTANDING WHY BERKEY FILTERS ARE NOT APPROVED FOR SALE IN CALIFORNIA AND IOWA

According to Berkey's website,

California

"Although [Berkey's] extensive testing is sufficient for 49 states in the US, it is currently not acceptable for residents in the state of California.

"Even after NSF certification has been obtained, the state of California additionally requires that companies pay high costs to obtain and maintain certification with the state of California.

After careful review, it has been concluded that the additional taxes, certifications, and red tape have created too large of a barrier for their dealers to offer the larger Berkey Systems in the state of California."

Iowa

"Even after NSF certification has been obtained, the state of Iowa additionally requires that systems further be registered with the Iowa Department of Public Health. One major problem arises because each flexible configuration we offer is considered by the state of Iowa to be a distinct and separate system that must be certified independently. Under Iowa legislation, the expense required to certify each system and maintain certification per configuration quickly becomes unaffordable.

"While this may not be a problem for companies that are inflexible with respect to the systems they offer or have few product offerings, such requirements place a huge burden upon companies that do offer such flexibility, (i.e. multiple variations of water filter systems).

"Berkey has concluded that the additional taxes, certifications, and red tape have created too large of a barrier for their dealers to offer Berkey Systems in the state of Iowa."

(Re California: Berkey is hardly the only company to avoid California. According to published reports, between 2009-2016 an estimated 13,000 businesses departed the state. In just the two years 2018 and 2019, which were "economic boom years," 765 additional commercial facilities departed "The Golden State.")

THE IMPOSSIBILITY OF PERFORMING THE RED DYE TEST AS DESCRIBED IN THE TEXT ACCOMPANYING THE VIDEO ON THE BERKEY WEBSITE

"8. Pour the red tinted water into your upper chamber. Your Black Filters should be fully submerged.

"9. Allow the full batch of water to filter from the upper container into the glasses below."

Problem: For the Big Berkey's Black Filters to be fully submerged, the upper chamber must be filled nearly to capacity, which is 2.25 gallons. Thus, #9 requires that the two glass jars that are shown in the video and that receive the output from our two Black Berkey filters must be capable of receiving about 1 gallon each. However, we are unable to locate two one-gallon glass containers that can fit together within the 8.5-inch diameter of the space below the upper chamber.
