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

5 Micron Nominal 20" x 4.5" Big Blue String Wound
WHY IT WORKS

Engineered for Higher Dirt-Loading Capacity

πŸŒ€

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

πŸ—οΈ

Durable Construction

Polypropylene media and core withstand temperatures from 40Β°F to 125Β°F, suitable for municipal water, well water, and many industrial fluids

βš™οΈ

Economical Performance

Reduces fine sediment including sand, silt, rust, and scale particles at 5 micron nominal rating with minimal pressure dropβ€”just 1 psi at 10 GPM

πŸ’§

Big Blue Capacity

20" x 4.5" dimensions provide extended filter life and higher flow rates for whole house and commercial installations
