Watts Premier (105321) 11" UF3 UF Membrane Filter Pure
11" UF3 Ultrafiltration Membrane Filter
The Watts Premier 105321 uses ultrafiltration hollow fiber membrane technology to remove suspended particles, bacteria, and high molecular weight contaminants without removing beneficial minerals. This 11-inch UF3 replacement cartridge operates on standard household water pressure and filters down to 0.2 microns through its semi-permeable membrane.
Ultrafiltration Membrane Process
Water Entry Under Pressure
Standard household water pressure forces water into the hollow fiber bundle, beginning the ultrafiltration process without pumps or electricity.
Semi-Permeable Filtration
Water passes through the 0.2 micron hollow fiber membrane. Suspended particles, sediment, bacteria, and materials of high molecular weight are physically blocked while water and dissolved minerals pass through.
Clean Water Delivery
Filtered water exits the cartridge with beneficial minerals intact, providing chemical-free purification that retains the natural taste profile of your source water.
System Requirements
This Watts Premier 105321 UF3 membrane filter is designed exclusively for use with the Premier FILTER PURE (UF3) ultrafiltration system. It is not compatible with reverse osmosis systems or standard cartridge housings. The 11-inch form factor and proprietary hollow fiber bundle configuration require the specific housing and inlet/outlet connections provided in the UF3 system.
