What Does Berkey Remove?

What exactly does a Berkey Water Filter System filter out? 

Over 200 contaminants are removed with Berkey water filter systems. We've extensively tested our filters and found our technology greatly exceeds the standards. Berkey removes contaminants from A to Z. Berkey filters go above and beyond testing standards, using EPA and state-certified labs to test above the EPA and ANSI/NSF (Std. 53) protocol. Based on the test data, Black Berkey Purification Elements (sometimes called Black Berkey Filters) elevate the system from a filter to a water purifier because it removes 99.9999999% of pathogenic bacteria (9-log reduction) and 99.999% of viruses. 



Yes, Berkey removes 99.9% of arsenic.

Learn more about Arsenic. Find out what it is, what is causes and how to remove it. 


Yes, Berkey removes 99.9% of bacteria.

Including: pathogenic bacteria and surrogates such as Raoultella terrigena, Bacillus atrophaeus (Anthrax Surrogate), and Salmonella Enterica.


Yes, Berkey filters out 99.7% of Cadmium and its harmful compounds.


Yes, Black Berkey Filters remove 99.9% and Berkey Shower Filters remove 95% of chlorine.

Learn more about Chlorine. Including the harmful byproducts such as haloacetic acids and trihalomethanes

Chromium 6

Yes, Berkey removes 99.8% of chromium 6.

Learn more about Chromium 6 (aka Hexavalent Chromium). Read more about the dangers of this compound and how it can get in your water. 

E. Coli

Yes, Berkey removes 99.9% of E. Coli.

AKA Escherichia Coli

Endocrine Disruptors

Yes, Berkey removes 99.9% of all endocrine disruptors.

Curious about what are Endocrine Disruptors? After you read that you'll know why we recommend using glass water bottles.


Yes, Berkey Fluoride Filters remove up to 97% of fluoride from tap water.


Yes, Berkey removes Glyphosate, the main ingredient in the common herbicide, RoundUp. 

Haloacetic Acids

Yes, 99.9% of all haloacetic acids (HAA5s) are removed.

Find out what Haloacetic Acids are, also known as HAA5s.

Heavy Metals

Yes, Berkey removes 99.9% of all heavy metals.

Including: Aluminum, Antimony, Barium, Beryllium, Bismuth, Cadmium, Cobalt, Chromium, Chromium 6, Copper, Iron, Lead, Mercury, Molybdenum, Nickel, Vanadium, and Zinc


Yes, Berkey removes 99.9% of lead.

Lead--What is it? How is it harmful? Why is it in your water?


Most likely. Tests show the removal of viruses in the range of 24-26 nanometers. This suggests that contaminants larger in size, such as plastic fibers, would also be removed.


Yes, Berkey removes more than 99.9% of all microorganisms.

Including: total coliform, fecal coliform, e. coli


No. Because we don't want to remove minerals!

Learn more about why beneficial minerals are left in Berkey water. This excludes zinc (see below).
