Pentek WP-BB97P Big Blue Sediment Filter - 0.5 Micron, 10in x 4.5in, Whole-House

Overview

The Pentek WP-BB97P Big Blue sediment filter is a 10-inch, 0.5 micron cartridge designed for whole-house protection. It uses a sturdy polypropylene string-wound media around a rigid core to trap fine sediments such as rust, sand, and silt. This configuration creates a larger filtration surface, helping to maintain steady flow while capturing more particles at the source.

Engineered with an anti-static winding process, the media reduces electrical charges during assembly, which can help minimize disturbance when a new cartridge starts up. The result is a practical, economical choice for homes and small facilities facing sediment challenges in municipal or well water. The cartridge is rated to operate up to 165°F (73.9°C) and supports a broad flow range, typically between 10 and 65 GPM, with minimal pressure drop.

Key benefits

• KEEP YOUR WATER CLEAN and protect appliances by removing dirt, sand, silt and particulates.
• FITS ALL 10" Big Blue housings and replaces common 10" x 4.5" sediment filters for easy upgrades.
• ECONOMICAL SOLUTION to reduce fine sediment, including rust, sand and scale particulates.
• HIGH DIRT-CATCHING CAPACITY AND FLOW RATES thanks to the string-wound construction, helping sustain performance.
• SUITABLE FOR USE IN VARIOUS APPLICATIONS, including drinking water purification, irrigation and industrial processes.

Performance and installation tips

• Temperature tolerance up to 165°F (73.9°C) supports diverse water conditions.
• Flow range from 10 to 65 GPM with minimal pressure drop helps maintain daily usage without noticeable slowdowns.
• Anti-static winding reduces charges during assembly to support predictable operation.
• Designed to fit all 10" Big Blue housings; a straightforward replacement for 10" x 4.5" filters.
• Works with municipal or well water, and is compatible with a variety of fluids in non-medical settings.

Note: Some foaming may occur during the initial startup of a new cartridge due to the static-reduction agent. This usually subsides quickly with continued use.

Real-world use cases

In homes with municipal water, unseen sediments can accumulate in faucet aerators, ice makers, and water heaters. The WP-BB97P captures fine particles before they reach these outlets, helping maintain cleaner taps and potentially reducing maintenance tasks.

For properties with well water or higher sediment loads, this cartridge provides a cost-effective layer of defense. Its durable polypropylene construction is designed to handle varying water conditions while maintaining a steady flow to all outlets.

Care and compatibility

• Easy replacement in any 10" Big Blue housing; standard 10" x 4.5" filtration dimension.
• Not a chemical treatment; it’s a mechanical sediment filter that should be replaced on schedule per usage and water quality.
• Regular inspection can help ensure optimal performance and prevent unnecessary pressure changes.
