Watts Premier R-300 Refrigerator Filter

You don't need to spend a lot of money on a new refrigerator in order to get clean, healthy filtered water and ice. This system works with any refrigerator with a 0.25'' water line. System comes complete with quick connect 0.25” fitting patented valve in head cap so installation of the filter head only has to be once. Filters can be changed with a simple twist, and you do not need to shut off the water supply since the system has an integrated shut off valve.
