Big Berkey beats ProPur gravity water filter for removal of heavy metals and toxic elements

Big Berkey water filter

(NaturalNews) When it comes to the removal of heavy metals and toxic elements from water, Big Berkey water filters easily beat ProPur, according to independent lab tests conducted at the Natural News Forensic Food Labs and published online today.

Full details of the tests conducted with parts-per-billion accuracy via ICP-MS instrumentation are shown at the new website www.WaterFilterLabs.com

As the data show, the Big Berkey water filter with attached arsenic / fluoride filter elements easily beat the ProPur water filter outfitted with the new "All-in-One" fluoride filter elements. In fact, according to the performance of the units we tested, Zen Water Systems also beat the ProPur water filter. (See lab test results chart below.)

Note: These tests were conducted solely for the removal of heavy metals and toxic elements, not pesticides, glyphosate, PCBs or other complex organic molecules. Additionally, this was not a microbiology test, so the removal of bacteria or viruses was not part of the scope of this testing.

Big Berkey also best at removing elements with radioactive isotopes

In this scientific assessment, we tested for the ability of popular off-the-shelf water filters to remove heavy metals such as lead, cadmium, arsenic and mercury as well as elements that have radioactive isotopes such as strontium, cesium and uranium. Finally, we also tested for aluminum reduction due to the chemtrails concern among many consumers today.

Natural News received no compensation from any of these manufacturers to test their products. All products were purchased "off the shelf" (at Amazon.com) at regular street prices, and none of the manufacturers were aware that we were acquiring their products for testing.

In these tests, the Big Berkey water filter vastly out-performed ProPur across all elements. For example, while the ProPur water filter only removed 20.2% of cesium, the Big Berkey removed 98.6%.

In our tests, arsenic removal by the ProPur "All-in-One" filter was 61.6%, while the Big Berkey filter removed 100%.

Full results of the removal results across all tested elements are available now at www.WaterFilterLabs.com

Here's a snapshot chart showing the results across five brands of gravity water filters:

Al = Aluminum
Cu = Copper
As = Arsenic
Sr = Strontium
Cd = Cadmium
Cs = Cesium
Hg = Mercury
Pb = Lead
U = Uranium

ProPur's new "All-in-One" filter elements far better than previous filters, but still not close to effectiveness of Big Berkey water filter elements

One of the interesting results from our tests is that ProPur's standard filters which have been sold for years performed relatively poorly in these tests.

In fairness to ProPur, we actually delayed the release of these results until we could acquire their new "All-in-One" filter elements and test those. The new "All-in-One" filter elements were significantly more effective than ProPur's standard filters, but were still not nearly as effective as the Big Berkey filters that we tested.

The following chart shows the improvement in toxic element reduction achieved by ProPur's new "All-in-One" filter elements vs. their previous standard filters:

As you can see from the chart, both filters performed almost identically for removal of Cesium and Mercury, but the new "All-in-One" filters were substantially improved across all other elements, especially lead and cadmium.


The conclusion from these tests is that Natural News can only currently recommend two gravity water filters for the removal of heavy metals and toxic elements:

• Big Berkey (with the arsenic / fluoride filters attached)
• Zen Water Systems

Big Berkey filters are available through a number of affiliates and representatives. Zen Water Systems filters are available on Amazon.com and other online retailers. Both filters offered outstanding performance in our tests. The Berkey filter, being made of stainless steel, is more of a "survival" style of filter, while the Zen Water Systems filter is more of a contemporary design, suitable for kitchens or office environments.

About the author:Mike Adams (aka the "Health Ranger") is a best selling author (#1 best selling science book on Amazon.com) and a globally recognized scientific researcher in clean foods. He serves as the founding editor of NaturalNews.com and the lab science director of an internationally accredited (ISO 17025) analytical laboratory known as CWC Labs. There, he was awarded a Certificate of Excellence for achieving extremely high accuracy in the analysis of toxic elements in unknown water samples using ICP-MS instrumentation. Adams is also highly proficient in running liquid chromatography, ion chromatography and mass spectrometry time-of-flight analytical instrumentation.

Adams is a person of color whose ancestors include Africans and Native American Indians. He's also of Native American heritage, which he credits as inspiring his "Health Ranger" passion for protecting life and nature against the destruction caused by chemicals, heavy metals and other forms of pollution.

Adams is the founder and publisher of the open source science journal Natural Science Journal, the author of numerous peer-reviewed science papers published by the journal, and the author of the world's first book that published ICP-MS heavy metals analysis results for foods, dietary supplements, pet food, spices and fast food. The book is entitled Food Forensics and is published by BenBella Books.

In his laboratory research, Adams has made numerous food safety breakthroughs such as revealing rice protein products imported from Asia to be contaminated with toxic heavy metals like lead, cadmium and tungsten. Adams was the first food science researcher to document high levels of tungsten in superfoods. He also discovered over 11 ppm lead in imported mangosteen powder, and led an industry-wide voluntary agreement to limit heavy metals in rice protein products.

In addition to his lab work, Adams is also the (non-paid) executive director of the non-profit Consumer Wellness Center (CWC), an organization that redirects 100% of its donations receipts to grant programs that teach children and women how to grow their own food or vastly improve their nutrition. Through the non-profit CWC, Adams also launched Nutrition Rescue, a program that donates essential vitamins to people in need. Click here to see some of the CWC success stories.

With a background in science and software technology, Adams is the original founder of the email newsletter technology company known as Arial Software. Using his technical experience combined with his love for natural health, Adams developed and deployed the content management system currently driving NaturalNews.com. He also engineered the high-level statistical algorithms that power SCIENCE.naturalnews.com, a massive research resource featuring over 10 million scientific studies.

Adams is well known for his incredibly popular consumer activism video blowing the lid on fake blueberries used throughout the food supply. He has also exposed "strange fibers" found in Chicken McNuggets, fake academic credentials of so-called health "gurus," dangerous "detox" products imported as battery acid and sold for oral consumption, fake acai berry scams, the California raw milk raids, the vaccine research fraud revealed by industry whistleblowers and many other topics.

Adams has also helped defend the rights of home gardeners and protect the medical freedom rights of parents. Adams is widely recognized to have made a remarkable global impact on issues like GMOs, vaccines, nutrition therapies, human consciousness.

In addition to his activism, Adams is an accomplished musician who has released over a dozen popular songs covering a variety of activism topics.
