Bath Ball Water Filter Options to Remove
Chlorine or Chloramines from Bath Tub Water
people regard a hot bath as one of life's little pleasures.
However, what many people don't realize is the danger of chlorine or
chloramines in the water. If you use unfiltered water, every time you
step into a hot, steamy bath, your body soaks up chlorine or
chloramines like a sponge and your lungs absorb their
vapors. You absorb more chlorine or chloramines when you bathe than you
do from your drinking water.
What Is Chlorine?
Chlorine is a poison that attacks organic matter, like bacteria in the water.
When chlorine enters the body as a result of breathing, swallowing or skin
contact, it reacts with water to produce acids. The acids are corrosive and
damage cells in the body on contact. Most harmful chlorine exposures are the
result of inhalation, especially while showering or soaking in a hot tub of
water. It is harmful to your hair, skin, eyes, nose and mouth membranes and
lungs. Chlorine leaves your hair brittle and dry, burns your eyes and makes
your skin dry, flaky and itchy.
Health effects can begin within seconds to minutes. Following
chlorine exposure, the most common symptoms are airway irritation, wheezing,
difficulty breathing, sore throat, cough or irritation of the skin or eyes.
The severity of health effects depend upon the route of exposure, the dose
and the duration of exposure to chlorine.
Chlorine byproducts can also affect health, such as Trihalomethanes (THM).
Trihalomethanes are formed as a by-product predominantly when chlorine is used
to disinfect water for drinking and bathing. THMs represent one group of chemicals
generally referred to as disinfection by-products (DBP). They result from the
reaction of chlorine and/or bromine with organic matter present in the water
being treated. The THMs produced have been associated through epidemiological
studies with some adverse health effects. They can be absorbed into the body
through the skin or by inhalation. When THMs are absorbed through the skin
or into the lungs, they hold stronger carcinogenic properties because they
aren't detoxified through the liver.
Although chlorine is universally used to disinfect water,
it is not safe for drinking, showering or bathing.
"Chlorine is so dangerous" according to biologist and chemist
Dr. Herbert Schwartz," that it should be banned. Putting chlorine
in the water is like starting a time bomb. Cancer, heart trouble, premature
senility, both mental and physical are conditions attributable to chlorine
treated water supplies. It is making us grow old before our time by
producing symptoms of ageing such as hardening of the arteries."
What Is Chloramine?
Chloramine is a mixture of chlorine and ammonia, which is added to the water
of many cities as a substitute for free chlorine. It is often referred to in
the plural as chloramines, because it can take on a number of forms according
to the pH and mineral content of the water.
At first, scientists knew only that chloramine didn't produce the same byproducts
chlorine did. But over time they learned that it could produce worrisome byproducts
of its own, including chemicals called nitrosamines.
the compounds that people warned you about when they told you you shouldn't
be eating those nitrite-cured hot dogs," Sedlak says. "They're
about a thousand times more carcinogenic than the disinfection byproducts that
we'd been worried about with regular old chlorine." -- David Sedlak
from the department of civil and environmental engineering at the University
of California, Berkeley.
How to Remove Chlorine and Chloramines?
There is no single media that will effectively remove both chlorine and chloramines.
While carbon is one of the most effective ways to remove chlorine, unfortunately,
most carbon is not designed for the hot water temperatures
of bath water because the hot water causes the carbon to expand,
and when carbon expands it releases contaminants stored in its pores. Also,
water above 94 degrees can cause the carbon to be less effective and can shorted
its life. Plus, most carbon types are not very effective at removing chloramines.
The types of medias that
work great in hot water up to 115 degrees are the
KDF 55 for removing or reducing chlorine
and water-soluble heavy metals and controlling scale, bacteria
and algae. This media is used with nearly all CuZn water filter products.
KDF 85 for removing or reducing chloramines, iron and hydrogen
sulfide and water-soluble heavy metals and controlling scale, bacteria and
algae. This media is used with the CuZn Bath Balls.
Pharmaceutical Grade Vitamin C (ascorbic acid) has recently
been included in AWWA (American Water Works Association) Standard (AWWA,
2005b) as one of themethods for dechlorination of disinfected water mains.
There are no NSF International certified point of use devices utilizing Vitamin
C, however SFPUC (San Francisco Public Utilities Commission) determined that
1000 mg of Vitamin C removes chloramine and chlorine completely in a medium
size bathtub. This media is used in the VitaBath
The most effective method is to combine medias, such as is done with CuZn
Bath Ball filters. For chlorine, CuZn combines KDF 55 with
Catalytic Carbon and for chloramines they combine KDF 85 and Catalytic Carbon.
Bath Ball Filter for Bath Tub Faucets
The CuZn Bath Ball is for people who want a quick, mess-less way to
fill their bath with clean, filtered water. It
hangs on a standard bath tub faucet that has a flow-engage knob on top
(see picture to right). CuZn Bath Balls lasts significantly longer than
other brands (15,000 gallons - 300 baths in a 50 gallon tub).
The Bath Ball utilizes the new
PowerDisk patented FilterFoam technology, designed exclusively by
CuZn for water filter applications. The new PowerDisk will eliminate
dirt, sediment, odors and chlorine that causes dry, itchy, flaky skin,
brittle hair, eye, lung and sinus irritation. Added PowerDisk benefits
are your bathtub will stay cleaner longer because the filter reduces
lime scale, mold, and mildew deposits and helps to soften your water
naturally (without salt!!) leaving your skin supple and smooth and
your hair soft, silky and manageable.
IMPORTANT NOTE: The
shelf life of replacements filters is 9-12 months, so do NOT stock
up on these filters.
NOTE: Chlorine in water may be present in two forms, free
and combined. Free chlorine does the hard work of killing bacteria and oxidizing
contaminants. When you add chlorine to water, you are actually adding free
chlorine. When the free chlorine combines with contaminants, it becomes combined
chlorine or chloramines. In water, this form of chlorine has very little sanitizing
ability, and no oxidizing ability. Total chlorine is just the sum of both combined
chlorine and free chlorine.
CuZn's KDF55 filter removes about 95% and the KDF85 removes about 75% of
both free and combined chlorine as a new filter and diminishes in capability
as the filter is used, as do all water filters. But bear in mind that if your
water company is using chloramine, there is little to no chlorine in the water. Read

There is only one accurate water test that is capable of measuring both free
and combined chlorine -- DPD#1 Test. Unfortunately, because of the nature of
the beast, false readings are common.
On Home Testing of Shower Filters
Chlorine in water may be present in two forms, free and combined. Free chlorine
does the hard work of killing bacteria and oxidizing contaminants. When you
add chlorine to water, you are actually adding free chlorine. When the free
chlorine combines with contaminants, it becomes combined chlorine or chloramines.
In water, this form of chlorine has very little sanitizing ability, and no
oxidizing ability. Total chlorine is just the sum of both combined chlorine
and free chlorine.
CuZn TurboShower Filters are designed to remove free chlorine (CL) from
water. Because of how Copper-Zinc works, OTO (orthotolodine pool testing
kits that measure chlorine in water) tests do not give accurate readings.
Copper and Zinc ions recombine with the chlorine molecules to produce cupric
chloride and zinc chloride. Therefore, any test that measures the CI ion
(such as OTO and some DPD tests) will show positive in the presence of cupric
chloride and zinc chloride. The test may show positive when testing the TurboShower
even though the TurboShower is working perfectly to remove the harmful chlorine.
The DPD #1 Test, which tests only for CI2 is the only way to accurately measure
the TurboShower's effectiveness.
However, even DPD #1 will not accurately test chlorine's removal from water
in the presence of chloramines. Chloramine is produced when a municipality
injects both chlorine and ammonia simultaneously into the water supply. This
is done to reduce CI2's ability to combine with organic matter in the water
and thereby produce potentially harmful trihalomethanes (THMs). Because chloramine
has less disinfecting ability than free chlorine, a higher concentration
of chlorine in usually used to get the same bacteria kill rate.1
Additionally, the presence of iodine ions in water will magnify the chloramine
interference when using the OTO and DPD test methods. Also, oxidized manganese
in the water may interfere with the DPD procedure.1,2
To get accurate readings of CL2 levels, an amperometric titration method
should be used because it is least likely to reflect interferences.
CuZn's KDF55 filter removes about 95% of free and combined chlorine; CuZn
KDF85 removes about 75% of free and combined chlorine as a new filter and
diminishes in capability as the filter is used, as do all water filters.
There is only one accurate water test that is capable of measuring both free
and combined chlorine -- DPD#1 Test. Unfortunately, because of the nature
of the beast, false readings are common, as described above.
For practical purposes, a person's body will tell him or her when the filtration
media is exhausted and is letting chlorine through. Besides one's nose noticing
the disagreeable chlorine smell, one's skin and hair will become dry, flaky,
and itchy in the presence of chlorine.
