With a two-stage filtering process, damaging chlorine is removed from your water and the pH is balanced followed by the removal of harmful VOCs and THMs. Your skin is the largest “organ” on your body and can absorb an incredible amount of chlorine and chemicals. Hey, the way we feel about any chemicals that a filter can remove with initials like that has to be a good thing! Consumer Digest rated the Aquasana Shower Filter “Best Buy” in 2006 and 2007. We got ours through Better Water Store where we also received an additional 5% off by signing up on their free “Water Filter Club”.
