Features of the Vitamin C Hand Shower
The newest and most superior technology ever to enter the shower filter market is more
environmentally conscious than traditional activated carbon, KDF or sulfur-based chemicals
such as calcium (or sodium) sulfite or sulfate. Vitamin is not toxic to humans and is known
to boost the immune system and improve skin and hair. This proprietary Vitamin shower filter
let you enjoy chlorine-free, odorless, clean and nutrient-rich showers year around.

Advantages of Vitamin over Traditional Technologies
Vitamin C dechlorination has a lengthy history. It has been used in EPA and APHA
methods for the dechlorination of lab samples. In the medical industry, it is the standard
for critical applications such as dialysis, where the introduction of chlorinated water or toxic
chemical would be catatrophic. Breeders of rare fish also choose this method of
dechlorination. Very recently, Vitamin dechlorination is being used in the treatment of water.
It fully neutralizes both chlorine and chloramines. There are several powerful arguments
for using Vitamin instead of KDF, activated carbon or sulfur-based compounds as
dechlorination agents. Vitamin utilizes ascorbic acid chemistry for dechlorination. It is
made with an essential vitamin for humans and many animals, which is known to boost the
immune system, improve skin and hair of humans. It is also the safest and least toxic of
dechlorination agents. The research by US EPA found that L-Ascorbic acid (Vitamin C)
reacts rapidly and stoichiometrically with active chlorine and has limited interactions with
disinfection byproducts. They found no interference from L-ascorbic acid or its oxidation
product (dehydroascorbic acid) in mutagenicity assays of chlorinated NOM using
Salmonella typhimurium TA100, with or without metabolic activation.

Traditional Shower Filter Technologies
Activated carbon filtration (AC) is effective in reducing certain organic chemicals and chlorine in
cold water. Chlorine is attracted to and held (absorbed) into the surface of the carbon particles.
However, the efficiency of absorption is quickly nullified when the water becomes warm. The
lifetime of an activated carbon shower filter is very short. An activated carbon shower filter gets
clogged very quickly by the dirt it is meant to stop. As soon as that happens, it immediately
starts to supply dirty water.
KDF, another widely used dechlorination media, is comprised of copper and zinc. It removes free chlorine by reversing the electrochemical process that originally separated the chlorine
from sodium in a brine solution. It can't, however, remove chloramines and, it's efficiency
depends on water temperature, it doesn't work well in cold water.
There are several other limitations using KDF as a de-chlorinating agent. KDF shower filters are also affected by water pressure. When the water pressure is not high enough, water
simply can't pass through the KDF powders. The major problem of KDF shower filters is
that the lifetime of the filter depends on the quality of the water passing through it. This is
truly a cath-22. When the quality of the water is bad, that's when we need a shower filter
the most. The dirt a KDF filter removes from the water quickly covers the surface of the KDF
that in turn makes the filter ineffective very quickly. When the quality of the water is clean,
we don't need a shower filter and KDF shower filters works great and will last a lot longer.
Other shower filter manufacturers use sulfur-based compounds such as calcium sulfite or sodium sulfite (or sulfate) as de-chlorinating agents. These sulfur-based compounds can
be toxic to humans. The addition of excess sulfite and sulfate chemicals to our water
supplies has always been a concern.
Reasons why general water purifying system cannot be used as shower water purifying
system.
*Tab water purifier uses carbon filter that eliminates chlorine from the tab water only
under 15?. As water temperature increases, carbon filter loses its function of chlorine
elimination in between 15C~32C, and when water is hotter than 32C, carbon filter
cannot perform its function at all.
* Water pressure becomes low, hence economically not efficient. Difference between Water Softener and Vitamin-C Shower Head * Water softener softens hard water into soft water, whereas, it does not eliminate chlorine from the tab water.
