POOLPURE PLFPWWCT150 is a direct-fit aftermarket pool filter cartridge that replaces PWWCT150, Ultral-B3, and Unicel 8414, offering 150 sq.ft of trilobal, 50-micron filtration for clearer water and easier cleaning.

Built to match common top-and-bottom open cartridges, this POOLPURE replacement combines a high-surface-area trilobal fabric with reinforced construction to capture fine particles and resist wear. It’s NSF/ANSI 50 tested for material safety and designed for longevity, so you get reliable performance in home and commercial pools that use the listed cross-reference part numbers.

How does this cartridge improve water clarity?

The PLFPWWCT150 uses multilayer trilobal fibers that provide increased surface area for trapping debris and suspended particles. An upgraded 50-micron layer targets fine contaminants, reducing cloudiness and lowering strain on pump and sanitizer systems.

• 150 square feet of filtration media for greater dirt-holding capacity
• Trilobal fabric offers three times more adsorption area than standard fibers
• 50-micron layer captures hair, fine sand, dust, and small organics
• Dirt-locking technology releases trapped debris easily during rinsing

How durable and easy to maintain is this cartridge?
