From the Manufacturer

The Aquasana Shower Filter has a unique two-stage filter process for the healthiest shower possible. Stage 1 removes chlorine and enhances pH balance with a natural copper/zinc mineral media called KDF-55D. Stage 2 uses a carbonized coconut shell medium for the removal of synthetic chemicals, THMs and VOCs that vaporize from tap water and are inhaled or absorbed through the skin, potentially causing adverse health and cosmetic effects. Anyone who has ever gone swimming in a chlorinated pool knows how chlorine robs moisture from your skin and hair. What most people don't realize is that typically there is as much or more chlorine in tap water as there is in most swimming pools. Chlorine strips the natural protective oils from skin and hair, causing excess dryness. Without the harsh effects of chlorine, you'll notice significant cosmetic benefits ... softer skin and hair in a week! Also, by removing chlorine and other chemicals found in tap water, now known to be a significant source of exposure to harmful VOCs and THMs, you eliminate health risks related to inhalation and skin absorption of these chemicals. Your shower water will feel better, and will be better for you!
