Aquasana AQ-4125 Replacement Filter

In stock

The AQ-4125 filter is intended for use as a replacement cartridge with the AQ-4100 and the AQ-4105 shower filter systems. It has a rated capacity of 10,000 gallons (38,000 litres) and can last for up to 6 months once it has been activated.

Filtration Capabilities

The AQ-4125 uses a 2-stage filtration method to remove contaminants from shower water. The first layer is made up of a blend of Zinc and Copper and is known as KDF 55 Process Media. It reduces Chlorine levels and helps to balance and enhance the water's pH. The second layer consists of AquaSorb HX Coconut Shell Carbon, which, like the first layer, reduces Chlorine levels and removes synthetic compounds. Between these layers, the AQ-4125 filter meets the NSF Certified Standards 42 and 61.
