Review on 🚰 KOHLER Aquifer Cartridge Filtration System 77685 NA by Leslie Little

Revainrating 5 out of 5

Water Pressure - Water Filtering and Softening

I have used Kohler water filters for many years. We have moved to a new house and installed a water filtration system using a KOHLER 77685-NA Aquifer cartridge to provide cold water under the sink. This reduced the water pressure by 2/3. It was easy to install, but I wouldn't recommend it unless you expect decent water pressure.

Pros
  • 0.85 GPM (max flow at 60 psi)
Cons
  • There are other interesting options.
