Beauty Begins in the Shower. Chlorine is one of the real culprits behind dry, damaged hair and skin. A survey of public water* shows that regular household water can contain nearly as much chlorine as that recommended for swimming pools. By using a patented formula of Tourmaline, precious metals and minerals, T3 Source Shower Filters can remove up to 95% of chlorine from shower water which: Improves hair health and beauty Enhances the color retention and vibrancy of processed hair Helps skin to be less dry, retain more moisture and look healthier Makes skin noticeably softer and smoother Discover the Pure Water Difference: Through a filtration process called "Redox", T3 Source Shower Filters transform chlorine into harmless elements that are too large to be absorbed by hair and skin. The patented technology is tested and certified by the National Sanitation Foundation (NSF) who is a US water supply auditor and world health organization member.
