Aquasana Shower Filter Replacement Cartridge AQ-4125 For AQ-4100

The Aquasana Shower Filter Replacement Cartridge fits both Aquasana Pure Shower Filter models, the standard AQ-4100 and AQ-4105 with massage wand. The unique US patented two-stage AQ-4125 cartridge usually lasts 6 months, depending on usage level and water quality. It installs in seconds and comes with easy-to-follow instructions.

In the first stage, water passes through a granular copper and zinc mineral media (KDF-55D). The second stage consists of a carbonized coconut shell media. Together, they effectively remove chlorine, synthetic chemicals, THMs (Trihalomethane), heavy metals, VOCs (Volatile Organic Chemicals), and other harmful chemicals, while balancing the pH.

The Aquasana AQ-4100 shower filter won the prestigious Consumer’s Digest magazine’s “Best Buy” award for 2006, 2007, and 2008! It was also voted "Product of the Year" by Cosmetology Today Magazine.
