The Berkey 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 will filter lime scale, mold, and fungi in your shower. Berkey KDF process media are completely safe so the process is not toxic and does not cause any adverse side effects.
Chlorine Vapor in the Shower
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 shower heads and shower filters to flow at 2.5 gallons of water per minute. Thus, the science behind shower water filtering must take into account the unique situation in the shower, including temperature, flow rate and volume. Berkey understands this process and took all of these factors into account while developing this unique filter.
The Berkey dual process KDF Shower Filter works on a similar principle to a catalytic converter in an automobile. Inside the shower filter free-chlorine is converted into a harmless chloride. The scientific name for this chemical reaction taking place inside the Berkey shower filter 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 Berkey 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. 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.
Berkey KDF process granules are high-purity copper-zinc formulations that are used in Shower Filter applications to reduce heavy metals, hydrogen sulfide, microorganisms, and scale. Shower water filtered through redox media controls microorganism growth and reduces bacteria and other microorganisms by electron transport, causing cellular damage. Inside the Berkey filter the KDF process also kill bacteria by direct electrochemical contact and by the flash formation of 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.
When pressurized shower water is filtered through the Berkey KDF filter media, soluble lead cations are reduced to insoluble lead atoms, which are electroplated onto the surface of the filter.
The improved Berkey Shower Filter™ unit will typically last 20,000 gallons or one year, whichever comes first. While testing was performed under standard laboratory conditions, actual performance may vary. The BerkeyShower Filter™ unit contains a new and improved showerfiltration media, which is most effective in reducing free chlorine, hydrogen sulfide, scale and iron oxide (rust water). The Berkey Shower Filter™ process media works in a wide range of temperatures with a maximum operating temperature of 120 degrees Fahrenheit.
Using a patented blend of high-purity calcium, copper and zinc; the Berkey Shower Filter™ unit 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. This is too large to evaporate or be absorbed by the skin. It is then carried harmlessly through the water supply.
NOTE: If possible do not use the Berkey ShowerFilter™ unit with a shut-off valve. If a shut-off valve is absolutely necessary, please make sure it is installed inline above and before theBerkey Shower Filter™unit. Use of a shut-off valve after the Berkey ShowerFilter™ unit may result in excessive pressure buildup inside the Berkey Shower Filter™ unit causing the filter to be damaged and voiding your warranty.
