TECHNICAL INFORMATION:
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.
