Pentair Pentek WP5BB97P Big Blue Sediment Filter 10-Inch, 5 Micron – Whole-House Filtration

Overview

Meet the Pentair Pentek WP5BB97P Big Blue sediment filter. This 5 micron cartridge is sized 10" x 4.5" and designed for whole-house use. Placed in a 10" Big Blue housing, it targets dirt, sand, silt, and particulates that travel with the water, helping to keep pipes and fixtures cleaner over time. The polypropylene string-wound construction emphasizes filtration accuracy while maintaining reliable water flow as it captures debris from every pass.

Compatibility and cost-efficiency are built in. The WP5BB97P fits all 10" Big Blue housings and can replace any 10" x 4.5" sediment filter. This makes it an economical choice for reducing fine sediment such as rust, sand, and scale particulates, without requiring a specialized housing or complex installation. The filter’s design supports consistent performance while keeping operating costs in check.
