A core reason to use shower filters is to remove chlorine. Chlorine is commonly added to water to disinfect it. Chlorine can be inhaled or absorbed through the skin during showering and bathing. Some individuals who are sensitive to chlorine could face severe skin irritation.

Disinfection by-products (DBP) can be absorbed through the skin during showering and bathing. Although health risks information is limited when being exposed to DBPs. Shower water filter devices can be used to lower disinfectant levels in home water.


One of the disinfectant byproducts that is created during water chlorination is chloroform. Earlier chloroform was used as an anesthetic. Unfortunately, chloroform can cause cancer. The United States Department of Health and Human Services considers chloroform to be “reasonably anticipated as a carcinogen. A warning is also issued by Environmental Protection Agency has also issued a warning about chloroform.

The only notable certification in this space is the NSF/ANSI 177, which is a certification for filters that attached directly to a water pipe before the water goes into a showerhead.

This certification and filter type isn’t designed to make the water potable, but rather to remove chlorine from the water. In the process of removing chlorine other contaminants will be removed, but the certification is aimed at the chlorine.

How Long Do Showerhead Filters Last?

Showerhead-based water filters will last for differing amounts of times depending on your water hardness and level of contaminants in your water (harmful or otherwise). Also some filters are larger and will last longer, depending on the brand you buy.

Typically, you can expect a showerhead filter to last for about 10,000 gallons or about 6 months of use for a full-time home.
