Pentek R30-BB Big Blue 30-Micron Pleated Sediment Filter - 10x4.5

Overview

The Pentek R30-BB Big Blue pleated sediment filter is built to fit standard 10x4.5 in Big Blue housings. With a 30-micron nominal rating, it captures a wide range of particulates — dirt, sand, silt, rust, and other sediment — before they travel deeper into your plumbing. The filter uses more than 16 square feet of durable, non-woven polyester media wrapped around a rigid polypropylene core, delivering greater dirt-holding capacity than non-pleated designs. A sonically welded overlap seam minimizes bypass, helping downstream filtration perform as intended. In residential, commercial, and light industrial settings, this cartridge can act as an efficient first line of defense for your water system.

Key advantages

• 16+ square feet of pleated media provides substantial surface area for dirt capture, supporting longer service intervals.
• Washable and reusable polyester media can be cleaned and reinstalled, extending cartridge life and reducing replacement costs.
• Molded polypropylene endcaps with integrated gaskets deliver a secure, leak-free fit in standard Big Blue housings.
• The sonically welded seam minimizes internal bypass, boosting filtration efficiency and consistency.
• Low initial pressure drop — less than 1 psi at 10 gpm — helps maintain steady whole-house water pressure.

How it works in your home

As a sediment pre-filter, the R30-BB targets visible and invisible particulates early in the filtration chain. By removing dirt and rust before reaching downstream filters and appliances, it can help reduce buildup and preserve flow, while supporting the performance of other filtration stages. The washable media also offers an option to extend service life when cleaning is appropriate for your system.

Care and usage tips

The R30-BB is designed for reuse where appropriate. Maintain your system by inspecting the cartridge during filter changes and following the manufacturer’s cleaning guidelines. Regular maintenance can help protect plumbing fixtures and downstream filtration stages while supporting steady water pressure throughout the home.
