Chlorine, the element CI, is a poisonous, gaseous substance that can be corrosive and hazardous to living things. However, when combined with other chemicals, it's also an effective disinfectant, widely used to clean water and other commonly-used materials. While much city water is treated with chlorine to reduce bacterial diseases, the federally-imposed limit on chlorine content in drinking water is 4 parts per million. If you are concerned about the chlorine level in your area, or you prefer to bathe in chlorine-free water, you can install a chlorine-filtering shower head.

Sprite Shower Filters
The shower head manufacturer, Sprite, specialises in shower heads that filter out chlorine. Sprite shower heads use KDF, a metal that converts chlorine into chloride, a harmless substance. Sprite's shower heads also add the mineral salt chlorgon to the water to combat combined forms of chlorine. Typically, you need to change the KDF cartridges once a year, though exact lifespan varies with the water's chlorine content. Sprite's models include the high-output shower head, in either white plastic or brass chrome and the hand-held shower head, in white plastic. As of September 2010, prices ranged from £26 to £35, shipping included. Replacement filters cost £14 to £16, depending on the model.
