Chlorine is a dangerous chemical used to kill bacteria in the water supply, water companies need to leave a portion of the chlorine in water to ensure that bacteria is controlled on the way from the treatment plant to our taps. It is up to us to remove that Chlorine at the point of use.

Experts agree that in a hot shower Chlorine and other toxic chemicals are absorbed through the skin and evaporated chemicals are breathed into the lungs, causing significant health risks:

"A long, hot shower can be dangerous. The toxic chemicals are inhaled in high concentrations." - Bottom Line - August 1987, J Andelman, Ph. D.

"Ironically, even the Chlorine widely used to disinfect water produces Carcinogenic traces. Studies indicate the suspect chemicals can also be inhaled and absorbed through the skin during showering and bathing." - U. S. News & World Report - 29 July 1991, Is your Water Safe - The Dangerous State of Your Water

"The steamy air of a shower contains significant amounts of a least two cancer-causing chemicals that evaporate out of water." -J Andelman, Professor of Water Chemistry, University of Pittsburgh

"A Professor of Water Chemistry at the University of Pittsburgh claims that exposure to vaporized chemicals in the water supplies through showering, bathing, and inhalation is 100 greater than through drinking the water."  - The Nader Report, Troubled Waters on Tap - Center for Study of Responsive Law

Chlorine in shower water also has a very negative cosmetic effect, robbing our skin and hair of moisture and elasticity, resulting in a less vibrant and youthful appearance. Anyone who has ever swam in a chlorinated pool can relate to the harsh effects that chlorine has on the skin and hair. What’s surprising is that we commonly find higher levels of chlorine in our tap water than is recommended safe for swimming pools.
