Review on 🚰 KOHLER Aquifer Cartridge Filtration System 77685 NA by Brandon Micali

I spent many hours researching before selecting this filter to replace the Woder filter I was using. This Kohler model has been tested to NSF/ANSI 42, 53, and 401 standards, which few under-sink filters can match. It was easy to install and the water is clean and tastes good. The flow rate for this filter is a little slow, but not slow enough to be a concern. They sell a model (KOHLER 77686-NA) that uses two of these filters to double the flow rate, which will surely be enough for most.
