Big Berkey, ProPur and gravity water filters: A lab testing update from the Health Ranger

Gravity water filters

(NaturalNews) Because so many Natural News readers have asked about the status of our water filter laboratory testing, I'm posting this update.

I've completed ICP-MS testing of the heavy metals removal capabilities of several popular gravity water filters including Big Berkey, ProPur, Doulton, Zen Water Systems and others. The results are all over the map. Some of these filters work extremely well to remove heavy metals, and others hardly work at all. You'll see these results published soon.

The ProPur filter has caused a delay because of the company's new "all in one" water / fluoride filters which I'm expecting to receive as early as tomorrow for final testing. The ProPur filter which was being sold before the arrival of these new filters simply did not perform well at all in terms of heavy metals removal. I had purchased the "ProPur BIG Stainless Steel Water Purification with 2 ProBlack-D Domed Hi-Performance Filter Elements" from Amazon.com, and the unit I received performed very poorly in our laboratory testing.

However, the company's new "all in one" filters that claim to remove fluoride are about to be tested separately. I anticipate these will perform far better because every gravity filter I've tested with a fluoride removal element has also been very good at removing heavy metals.

The Big Berkey's fluoride removal filters, for example, were very good at removing heavy metals. Fluoride filters often use ion-exchange technology which tends to be very effective at capturing all sorts of toxic elements beyond mere fluoride.

The reason I've delayed the publishing of the results until I get the ProPur fluoride filters tested is because I didn't think it would be fair to compare Big Berkey's fluoride filters to a ProPur unit that was not equipped with fluoride filters. Apples and oranges, as they say.

My upcoming results will show you exactly what percentage of each element is removed by each filter, and I even test for removal of elements that have radioactive isotopes, such as strontium, cesium and uranium. Nobody else anywhere in the world is conducting such detailed laboratory tests on water filter performance, so Natural News is the exclusive source where you can find this information.

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.
