Review on Enhanced KOHLER 77688 NA Aquifer Replacement Cartridge for Superior Performance by Justin Butler

A plumber installed a filtration system a few years ago. We're happy with the taste of the water and it's relatively easy to change the filters (just make sure you turn the water off before changing the filters! We messed up the first time and the kitchen floor was covered in water!) . My main complaint is that the filters last a maximum of 3 months; then the water drains slowly. Paying $95 to change the filter every time is expensive for a year. It's just my husband and I, but we fill two 64 oz. water bottles daily.
