Berkey Shower Filter Replacement

The Shower Filter contains a patented high-purity blend of zinc, calcium, and copper, effectively reducing free chlorine, dirt, and odors.

Tested and certified to meet or exceed ANSI/NSF Standard 177 for Shower Filtration.

The shower head has a flow rate of 1.75 gallons per minute in compliance with the California Energy Commission.

Designed and assembled in the United States.

Chlorine Vapor in the Shower

Chlorine can either be in a liquid or gas state in the shower environment. 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 each water filter for shower use, and all shower filters must flow at 2.5 gallons of water per minute. Thus, the science behind shower head water filtering must consider the shower's unique situation, including temperature, flow rate, and volume. 

The Shower Filter works similarly 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 inside the Shower Filter is known as "Reduction-Oxidation," commonly referred to as Redox. Redox reactions can be chemically complex. Electrons are transferred between molecules during a Redox reaction, 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 more prominent chloride element, too large to evaporate or absorb in the skin. Hospitals, restaurants, municipal water treatment facilities, and homes rely on this same process media to safely reduce or remove free chlorine and hydrogen sulfide from their water.

Filter media granules are high-purity copper-zinc formulations used in shower filter applications to reduce hydrogen sulfide, microorganisms, and scale. High-purity copper-zinc redox media consistently remove most free chlorine by electrochemically reducing dissolved chlorine gas to water-soluble chloride ions.

When pressurized shower water is filtered through the filter media, soluble lead cations are reduced to insoluble lead atoms, which are electroplated onto the surface of the filter.

Filter replacement:

All Shower Filters purchased typically last up to 20,000 gallons before needing replacement or one year, whichever comes first, in which case you would need to shop for and buy another one online.

 Notice of Limitations:

• --The Shower Filter is designed for potable water systems only.
• --Do not allow to freeze or use water over 110 F (43 C) temperature.
• --Maximum water pressure should not exceed 100 psi.
• --Do not use high iron content water systems that use chemicals such as polyphosphates.
• --The Shower Filter is not to be used for drinking purposes.
