Chlorinated Water and Unknown Hazards of the Shower
There is another side to the chlorine-water story.
When we return from a gym workout or a jogging session or a game of squash, not only are we thirsty but we usually shower or bathe.
We have been taught that cleanliness and health go together, and indeed they do, when chemical-free water is used.
When chlorinated water is used, however, bathing may be much less healthy that we ever supposed.
Gasses are as a rule less soluble in hot water, and when water is heated or the free chlorine content in water is greatly reduced, the chorine escaping into the air.
When we have a hot shower or run a bath we can sometimes smell the chlorine released as it escapes from the hot water. In a confined shower recess, however, especially one with poor ventilation, the chlorine escapes from the water as we continue the hot shower and steadily increases in concentration in the air we breathe.
The olfactory threshold for chlorine is about 3.5 PPM (parts per million) so when we can smell chlorine the concentration is already above this level.
The lethal concentration for ten-minute exposure is about 600 PPM and we suggest that regularly taking hot showers with chlorinated water could pose a health risk.

SH-1. Our economy KDF shower filter (for municipal water) uses the patented KDF copper-zinc alloy (manufactured by KDF Fluid Treatment, Inc.), the most effective media there is to remove chlorine in high temperature shower water. KDF's performance actually improves the higher the water temperature, whereas carbon's (used by some) performance decreases!
With this technology, our filter has been shown to effectively remove 97+% of this damaging chlorine, for up to 15 months (for 2 people) - 2 to 3 times longer than other filters. Treats about 18,000 gallons--get approximately 1800 five minute showers.
KDF also removes iron and other heavy metals, sulfur, pesticides and it controls the mold and mildew in your shower.
Our KDF Shower Filter installs in minutes, with no tools on any shower arm with standard 1/2" pipe threads. Simply unscrew your shower head from the shower arm, attach your shower head to the end of the filter, and install the filter on the shower arm.
