The FREEDERM CQ1000 De-chlorinating Shower Filter with Massage Action Shower Head was developed for our clients that suffer with eczema, psoriasis, or just plain dry skin. This product treats the water as it comes out of your shower so you will not be infecting your skin and scalp with harmful chemicals such as chlorine. This inovative new product installs without the need of a plumber. Just unscrew your existing shower head, and put ours up. It's that simple! The filter inside lasts a full 6 to 9 months and as you can see below the replacement filters can be purchased from us at a very cheap price. Have healthier looking skin, hair, and scalp after just a few days of use. SAVE MONEY WHEN YOU PURCHASE OUR HEAD-TO-TOE package below.
