Compatible 105321 UF-3 Ultrafiltration Membrane

Hollow-fiber membrane replacement for Watts Premier UF-3 systems
105321 Compatible Hollow-Fiber Membrane Replace Annually Part IPW105321

The IPW105321 is a compatible replacement for the Watts Premier 105321 UF-3 membrane (the purple filter). Its hollow-fiber ultrafiltration membrane physically blocks fine particles, sediment and microorganisms while letting water and dissolved minerals through, so your water keeps its natural taste. It is the final, annual stage of the UF-3 system.

HOW IT WORKS

Ultrafiltration Membrane Process

1
INLET

Pre-Filtered Water Enters

Water arrives already cleaned by the sediment and carbon stages, then household pressure pushes it into the hollow-fiber bundle. No pumps or electricity needed.

2
MEMBRANE

Hollow-Fiber Ultrafiltration

Water passes through the walls of thousands of hollow fibers. Fine particles, colloids and microorganisms are held back while water and dissolved minerals pass through.

3
OUTLET

Clean Water Delivery

Filtered water leaves the membrane with its minerals intact, ready for drinking and cooking.

Replace once a year
COMPATIBILITY

System Compatibility

Fits Watts Premier UF-3 (Filter-Pure UF-3) ultrafiltration systems in place of the 105321 / F105321 membrane. It is the purple filter in the 560039 annual kit, alongside the 105311 sediment filter (red) and 105371 carbon block (blue). Not for reverse osmosis systems or standard 10" housings.

Pro tip: Replace the membrane once a year, and change the sediment and carbon filters every 6 months to protect it.
