Berkey Water Filter News and Views presents articles related to drinking water.
The Berkey water filter is the simplest, most effective method of water treatment available. All things taken together your Berkey can provide you with high quality water in almost any circumstance where fresh water is available - pond, pool, lake, river, stream or puddle. Everyday or in an emergency your Berkey filter works because it uses no electricity. No other water filter can match the Berkey water filter for all-around convenience. Information is the key to good decision making and we at Berkey Water Fitler System hope these articles help you to make the decision to make a Berkey part of your lifestyle.


Chlorine is the greatest crippler and killer of modern times"

In a work sponsOred by the US EPA Dr. Robert Carlson states "Chlorine is the greatest crippler and killer of modern times". Now, while I personally donīt accept that statement at face value, it is certainly powerful enough to give me pause to think.

City water departments have depended on this chemical to kill microbial water contamination for years. It has been effective for that purpose. I works in much the same way that one might use it to keep a swimming pool clean. First filter out the visible particles and then add bleach to inhibit the growth of any living thing.

Here's some good news - Berkey filters remove chlorine from your water, making it safe, fresh-tasting and free of chlorine odor.

Chlorinated water is not good enough for chickens

In a report by Dr. Joseph Price it was stated that "Most large poultry producers now use water that has been dechlorinated. They discovered that the dechlorinated water produces birds that are healthier, grow faster and display more vigorous health".

I personally think that if itīs not good enough for chickens itīs probably not so great for humans either. Many researchers agree. Chlorine is, in fact, defined as a pesticide by the EPA.

According to the US Council of Environmental Quality "Cancer risk among people drinking chlorinated water is 93% higher than among those whose water does not contain chlorine".
It is being discovered that many of the adverse health effects are a result of its bi-products.
Other methods of disinfecting municipal water are being used in some areas. The health effects may not be evident for many years.

Berkey Shower Filter Can Reduce Chlorine Exposure Where It is Greatest -  in a Hot steamy Shower

Chlorine in water vapor has an equally negative effect as chlorine in drinking water. Chlorine and especially the bi-products formed by it's combination with water, can also be absorbed through the skin. If chlorine is the method used to disinfect your water then the steamy air your breathing in during your morning shower can result in higher exposure then that from drinking water.

Fortunately there are solutions:

  • Shower in cold water - not likely
  • Don't shower at all - not friendly
  • Hold your breath while you shower - not a bad idea if you like short showers
  • Use a Berkey PF-2 filter - good choice.

The dual media KDF Shower Filter will typically last 10,000 gallons or one year whichever comes first.

The shower filter contains KDF 55 granules, which are most effective in removing or reducing chlorine, hydrogen sulfide, microorganisms, scale and water-soluble heavy metals such as lead, mercury, and iron.

KDF process media also kill bacteria and inhibit the growth of bacteria, algae, and fungi.

As an added benefit, KDF media reduce lime scale, mold, and fungi in your shower.

KDF process media are completely safe so the process is not toxic and does not cause any adverse side effects. Effective for both hot and cold water.


In the shower environment, chlorine can either be in liquid or gas state. At higher water temperatures in the enclosed shower stall, free-chlorine moves from the liquid to the gas state, where it vaporizes and subsequently is inhaled. The United States regulates all showerhead flow at 2.5 gallons per minute. Thus, the science behind shower filtration must take into account the unique situation in the shower, including temperature, flow rate and volume.

Our Dual Media KDF Shower Filter works on a similar principle to a Catalytic Converter in an automobile. In shower filtration, free-chlorine is converted into a harmless chloride. The scientific name for this chemical reaction is known as "Reduction-Oxidation", commonly referred to as Redox. Redox reactions can be chemically complex. Simply stated, during a Redox reaction electrons are transferred between molecules, creating new elements. For instance, when free-chlorine comes in contact with the filtration media, it is changed into a benign, water-soluble chloride. This reaction changes free-chlorine to a larger chloride element, too large to evaporate or be absorbed by the skin. It is then carried harmlessly through the water supply. Hospitals, restaurants, municipal water treatment facilities, and homes rely on KDF process media to safely reduce or remove free chlorine, iron, iron oxides, heavy metals, hydrogen sulfide and bacteria from their water.

KDF process media are high-purity copper-zinc formulations used in treatment applications to reduce heavy metals, hydrogen sulfide, microorganisms, and scale. Water filtered through redox media controls microorganism growth. Treating water reduces bacteria and other microorganisms by electron transport, causing cellular damage. KDF process media also kill bacteria by direct electrochemical contact and by the flash formation hydroxyl radicals and hydrogen peroxide, both of which interfere with a microorganism's ability to function. High-purity copper-zinc redox media consistently remove 99% of free chlorine by electrochemically reducing dissolved chlorine gas to water-soluble chloride ions.

Redox media remove up to 98% of water-soluble cations (positively-charged ions) of lead, mercury, copper, nickel, chromium, and other dissolved metals. When filtered through KDF media, soluble lead cations are reduced to insoluble lead atoms, which are electroplated onto the surface of the media. All forms of KDF media are guaranteed for product purity, and a certified analytical sheet accompanies each manufacturing run. KDF media also meet EPA and Food and Drug Administration standards for maximum limits of zinc and copper in potable water.
