Watts Kwik Change 3-Stage Ultrafiltration System


This is a 3-stage, undersink filtration system with Kwik Change replacement filters that are easy to both identify and install. These filters come in three sizes: 10", 11" and 13". Make sure you order the size of filter you want for your system. If you are upgrading from the 10" or 11" filters to the 13", make sure you have enough space under your sink for the longer filters. If you are not sure what size filter you have, you can find the part number on the bottom.
