Pentek - WP5BB20P - 20" x 4.5" Polypropylene String Wound Filter
20" x 4.5" Polypropylene String Wound Filter WP5BB20P
Precision-wound polypropylene sediment filter with 5 micron nominal rating for high-capacity whole house, well, and commercial applications
Engineered for Higher Dirt-Loading Capacity
Precision Wound Pattern
Polypropylene cord wound in a precise pattern around a rigid core creates greater surface area than standard wound cartridges, improving efficiency and capacity
Durable Construction
Polypropylene media and core withstand temperatures from 40°F to 125°F, suitable for municipal water, well water, and many industrial fluids
Economical Performance
Reduces fine sediment including sand, silt, rust, and scale particles at 5 micron nominal rating with minimal pressure drop—just 1 psi at 10 GPM
Big Blue Capacity
20" x 4.5" dimensions provide extended filter life and higher flow rates for whole house and commercial installations
