KDF Shower Water Filter

The best shower water filter with patented KDF 55 media Filtering chlorine from your shower water benefits you, and it’s also a great way to protect the resin to ensure it performs well and has a long life.


KDF Shower FilterOur shower filter contains 100% KDF 55 media. Using a filter that contains KDF 55 media is the most effective way to remove chlorine in hot shower water temperatures. Tests have proven that carbon shower filters do not perform well in hot shower water temperatures, only in cold. And our KDF 55 media shower filter is effective for one year, unlike most other shower filters that need to be replaced every 6 months. Plus, unlike most other shower filters, this one will ship to you from the United States!

PLEASE BEWARE of other shower filters such as those that contain “stages”. For example, those that contain 12-stages might contain KDF 55 media but since they also contain 11 other items, there’s therefore only 1/12th the amount of KDF 55 media as ours has. How long can that tiny of an amount of KDF 55 media filter chlorine? Most likely, around 1/12th as long as ours – one month! And what exactly are the other 11 items? Do they really do anything to filter chlorine or anything else from your water? Chances are that the company who sells them doesn’t even know. And they might not even show a list of everything included in the 12 stages and an explanation of what they do! They’ve found a way to attract buyers with a clever (but not so honest) marketing technique (stages) to try to make their filter stand out from the others. But is having more “stages” really going to do a better job? And in that tiny of a quantity of each one? Having 100% KDF 55 media inside the chamber of a shower filter is the very best way to filter chlorine (and other contaminants shown below) in a shower. KDF 55 media received NSF International Certification and is certified by NSF to NSF/ANSI Standard 42 – Drinking Water Treatment Units – Aesthetic Effects. This media is also in compliance with California’s Health and Safety Code Section 166875 (or commonly known as AB1953) and Vermont Act 193.

Also, BEWARE of false and misleading claims made by several online sellers of Shower Water Filters (made with KDF media, carbon or anything else) that they “soften” water. THEY DO NOT SOFTEN WATER! SOFTENING THE WATER REQUIRES THE REMOVAL OF CALCIUM AND MAGNESIUM which a shower FILTER is not capable of doing (see for yourself by using a hard water test kit). A shower “filter” mainly removes chlorine which is why so many people who try using shower filters alone don’t get the results they were hoping for. To obtain soft water in a shower you need to use a SOFTENER such as a whole house water softener or the portable ShowerStick shower water softener made by WaterSticks (that’s us)! Our ShowerStick contains resin beads (as a whole house softener does) that work via Ion Exchange to remove hard water minerals. So, if you have skin conditions such as psoriasis or eczema (also known as dermatitis) or just very dry skin and/or hair you’ll most likely see better results when you soften the water than when you only remove chlorine. And you’ll see the best results when you soften AND filter the water. This is the reason we recommend installing the KDF filter in-line with the ShowerStick softener (the water should flow through the filter first in order to filter and protect the softening resin inside the ShowerStick from chlorine).

The KDF shower filter contains the most effective media there is to remove chlorine in high temperature shower water – patented KDF 55 copper-zinc alloy. KDF media actually becomes more effective in higher temperatures (such as in a hot shower) but this is not the case with other filters such as those containing carbon – theirs becomes less effective!

KDF 55 media received NSF International Certification and is certified by NSF to NSF/ANSI Standard 42 – Drinking Water Treatment Units – Aesthetic Effects. This media is also in compliance with California’s Health and Safety Code Section 166875 (or commonly known as AB1953) and Vermont Act 193.

Chlorine dries out the natural protective oils found in your skin and hair. That’s why a long swim in a chlorinated pool dries your skin and damages your hair. Chlorine vaporizes quickly in a hot shower, so you end up breathing chlorine gas. This isn’t good for anyone, but chlorine can have a major impact on people with asthma. Prove it for yourself: run a hot shower in an enclosed bathroom for 5 minutes then check for the chemical smell. That’s chlorine. Chlorine is universally used to disinfect water, killing bacteria and other microorganisms. But once it arrives in your home, chlorine can negatively affect your family’s long term health, comfort, and even personal appearance. According to Rutgers University, “We take in as much or more chemicals from showering as from drinking water…”


The KDF Shower Water Filter can be installed in-line with the ShowerStick or it can be installed by itself in a shower. It installs in minutes with no tools on any shower pipe with standard 1/2in pipe threads. To install by itself in a shower, simply unscrew your shower head from the shower pipe, attach the KDF filter to the shower pipe then add your shower head.


The KDF filter should be replaced yearly if 2 people are using the shower (or sooner if you smell the presence of chlorine).
