As shower filters and shower filter technology have advanced and changed frequently in the last 2 years, it is becoming difficult to keep up with what is the best filter technology and what we need to be concerned with. It seems when one test is completed, a new one is on the market.

KDF: This is by far the most popular and most capable filtering element in shower filter technology. It is widely accepted to be an excellent and long lasting filtration media for shower filter elements. While this filter media is considered excellent for removal of all types of chlorine, it is better at free chlorine neutralization.

GAC: Granular activated carbon is typically used for drinking filters and low-flow filters. There have been many manufactures that attempt to use this in shower filters. All studies indicate it does a poor job. The filter media does not last very long, and it spits out a black ooze which must be immediately cleaned. This filter element has varying filtering ability depending on water quality and water temperature.

Chlorgon: This is a combination of calcium sulfite with a ceramic binder. This has turned out to be a huge surprise in the shower filter market. This filter media, when combined with KDF has an amazing ability to reduce combined chlorine. Shower filters with this element are more difficult to find because the chemical makeup of chlorgon is proprietary and patented. Make sure your shower filter has this element.

Minerals, PI, Special Blend, Ceramics: These are all useless. Mostly they are used as add-on sales and marketing ploys. No filters that use these types of materials test very well at all.

Check with your shower filter company and make sure you are getting the best filter available, your skin and body will thank you.
