High-Output Shower Filters Did you know that most people on a chlorinated water supply inhale and absorb more chlorine when showering and bathing than from merely the drinking the water?

Chlorine vaporizes in hot shower water and, when inhaled in the lungs, is transferred into the blood stream. Chlorine is an oxidizing agent and changes into new compounds called trihalomethanes (thm's) including chloroform and bromoform when it mixes with organic material present in all water sources.
