Big Berkey Gravity-Fed Water Filter with 2 Black Berkey Purification Elements

Product Information

Moving up to a couple with double the drinking water needs and perhaps some extra water needed for cooking, the Big Berkey water filter seems about right. Our estimates peg this at about four and a half to five gallons a day. This would come out to the same three years as in the example above with a two-filter setup. With four filters, double that and go six years between replacements. Over the years we have multiple people trying to disregard the Berkey® Brand and writing up articles / blogs or social media posts with no legal claims or official test result like this post you are referring to. You pour water straight from the upper chamber of stainless water containers then safe and filtered potable drinking water is now stored in the lower chamber, ready for drinking. If your water is muddy or really dirty we advise pre-filtering your water by running it through some type of cloth, ie: shirt, bed sheet, bandanna, etc. before putting it in your Berkey® system. Studies have shown that natural alpha emitters are bone seekers in drinking water. As such, radium -226 and radium -228 can potentially produce harmful radiation doses. Exposure to high radionuclides levels can result in toxic kidney effects and an increased risk of cancer.

I have seen a test carried out by Berkey which shows it removed progesterone in water. The test did not show anything about oestrogens but when I researched water filters Berkey came up as the only filter that removes disruptors as reverse osmosis and ionisations does not. As oestrogen is far more damaging than progesterone to the body, I would like to know if in fact the Berkey does remove this? Berkey Purification systems do not remove all beneficial minerals from the water. Still, they extract harmful heavy metals such as lead and mercury and sedimentary minerals such as iron oxide. Therefore, the TDS reading will not typically change much unless there are a lot of heavy metals or sedimentary minerals within the source water.

The Big Berkey’s manufacturer, New Millennium Concepts, claims the filter can remove more than a hundred contaminants, far more than other gravity-fed filters we’ve researched. We tested these claims on a limited scale, and our results were not always consistent with lab results that New Millennium commissioned. In particular, results from both our commissioned lab and the lab most recently contracted by New Millennium showed less effective filtration of chloroform than that third, earlier test (which is also listed in New Millennium’s product literature). The reduction level chosen is the lowest amount of potential contaminants in a sample that can be accurately determined, given the laboratory test equipment available. This value is determined following EPA protocols and verified by an annual EPA audit. This Berkey filters are gravity based and can safely transform any type of water into safe drinking water including rain water, pond water. Take a look at the table below. The influent water level in this test was spiked with fluoride to 2.10 mg/L or higher. The columns “Effluent Fluoride” and “Fluoride % Reduction” show the filtered fluoride levels.

So don’t worry about if you are getting the right product. When someone talks about our product on a blog, sometimes some blog systems automatically correct the spelling to “Berkley” despite their intention. Why do the log reduction levels differ for varying Berkey® element tests? Some laboratory results show testing to greater Log reduction (example: 99.9% vs. 99.99999%) than others. Berkey water filters are utilized worldwide to set the international standard for water filters used in clean or hostile filtration environments.Berkey water filter systems are rated the best and longest lasting water filter systems on the market and they are the top performing portable water filters in the industry. Various laboratories offer different log reduction levels for which they can test. Typically, the higher the log level of testing, the higher the cost per contaminate. In other words, testing to Log 4 reduction levels costs much more than testing for Log 3, etc. It is a function of cost vs what log levels are necessary for customers to determine the effectiveness of our elements in removing a broad range of contaminants. According to the World Health Organization, a non-government agency, Arsenic is one of the major causes of poisoning and death since Arsenic is naturally found in groundwater, which is the source of drinking water in some undeveloped countries in the world. PF-2 filters contain high-grade activated alumina (Al2O3), which currently is the most efficient media available for extracting fluoride from water.

Berkey Water Filter is a great survival gear in emergencies as it works without electricity and can purify raw, untreated water from remote lakes and streams. It is the best gravity water filter for off-grid living. ♛ Berkey Saves Your Money For everyday water filtration, most NSF/ANSI–certified water pitchers and undersink filters are smaller, more convenient, far less expensive to buy and maintain, and easier to use. And they also provide the accountability that comes with independent, transparent testing. What are the Berkey filters made of and how can they last for so long time with constant usage ? Can you please explain for me as most filters on the market don,t last as long as the Berkey filters. Thanks Reverse Osmosis uses a membrane which removes many contaminants from the water. It is usually paired with a Granulated Activated Charcoal filter to remove chlorine and many mount under the sink usually.

Berkey Filters Test Results

Very infrequently, the filters can have a defect. If for some reason, they are not working after troubleshooting the possible problems. BerkeyHome stands by our high-quality products and excellent customer service. YES. The elements are bacteriostatic and YES, the bacteriostasis does prevent mitosis and will not allow any life forms to colonize within the element. However, this is not true of all filter elements on the market today. Many filter elements will support microscopic life forms and have no ability to augment bacteria blooms within the catalysts. Always be sure your elements are bacteriostatic. Re-prime the filters. If you’re not familiar with this process please visit our YouTube channel with step by step instructions, here. Berkey water filters are the best choice because they are easy to use even without electricity and are simple, healthy, efficient, cost-friendly, eco-wise, and highly reliable. Please make sure the food coloring is RED. Red food coloring (unlike the other colors) doesn’t have any minerals, so the element recognizes it as contaminant.
