Why Should You Buy a Shower Water Filter?

There are many advantages to owning a shower water filter. Since most municipal water is treated with chlorine, the environment of a shower can be detrimental to one's health if the water is not filtered. This is especially true when the shower is hot, as the steam contains chlorine in vapor form. This chlorine is breathed in and absorbed through the skin, which is the body's largest organ. Over time, daily exposure to chlorine can cause respiratory illness, asthma, and even certain types of cancer. Chlorine may also dry out your skin and hair; a shower water filter can soften the texture of skin and hair that has been consistently exposed to chlorine in the past. (For more information on the benefits of using a shower filter, see our article, "The Advantages of Shower Water Filters.")

What Contaminants Do Shower Water Filters Reduce/Remove?

Chlorine is the major concern for people who are in the market for a shower water filter. However, shower filters utilize various filter media to reduce other harmful contaminants such as: chloramines (which many water treatment plants are now using as a disinfectant alternative to chlorine), VOCs, scale, rust, sediment, iron oxide and hydrogen sulfide.

More About Shower Filter Media Technology

Shower filters may use one or a combination of two or more of the following types of filtration technology:


Carbon filters remove chlorine, chloramines, VOCs and other synthetic chemicals often used in water disinfection, by the process of carbon adsorption, in which the chemicals stick to activated carbon. These are the most comprehensive shower filters, but since the adsorption process requires a lot of surface area, they are typically larger than other filters. Moreover, carbon filters are typically made for use with cold water (i.e. drinking water) and will not be as effective in a hot shower.

Kinetic Degradation Fluxion (KDF)

KDF is an oxidation-reduction media made from copper and zinc. KDF shower filters work electrochemically, converting chlorine into soluble calcium chloride, which is harmless. However, KDF alone will not remove chlorine or VOCs and is often combined with Chlorgon filter technology.


Chlorgon was specially developed and patented by Sprite Industries, and is only found in Sprite shower filters. It is made to work more efficiently with hot water temperatures, and is therefore an ideal media for shower water filters.

Crystalline Quartz

Crystalline Quartz is added to some shower water filters to maximize lathering for a more "energy-enhanced feel."
