| Watts Premier (105321) 11" UF3 UF Membrane Filter Pure |
 UF Hollow Fiber Technology Membrane Filter. Hollow Fiber Technology uses ultra filtration, a membrane filtration process which uses standard home water pressure to push water through its semi permeable membrane. Suspended particles and materials of high molecular weight are unable to pass through the .2 micron UF membrane, leaving you with only fresh clean water and dissolved minerals to pass through. Compatible with ONLY the Premier FILTER PURE (UF3) filtration system. Price: 39.99 |
