How to Install Shower Filters

Shower filters work to remove chlorine and other toxins from your water. While chlorine kills germs and eliminates mold in drinking water, it can be very hard on your skin when you bathe. A filter helps to reduce that damage, as well as remove harmless metals and other elements from the water. Filters are particularly recommended for areas with a high saline content in the water, such as those near the seashore. They are available at most home supply stores and can be installed without the services of a plumber.


  1. Remove your existing shower head with a wrench or pliers. In some cases, the shower filter contains a built-in shower head, in which case you can set your old head aside. Otherwise, you'll need to keep it handy to reconnect once the filter is installed.
  2. Wrap white plumber's tape around the threads of the shower pipe. This helps cut down on leaks.
  3. Connect the top of the filter housing to the shower pipe. In most cases, you can simply screw it into place. In other cases, you may need to use a wrench.
  4. Place the filter in the bottom of the housing. Screw the bottom of the housing onto the top. Ensure the seal is tight.
  5. Reattach the shower head to the bottom of the housing (if necessary). Turn on the shower to check for any leaks.

Tip

  • The filter needs to be changed out periodically. With most models, simply unscrew the bottom of the housing, remove the old filter, and place in a new one. The packaging should tell you how long the filter will last, but the exact period depends on the quality of your local water supply.
